Objects move when they change position. Understanding Distance, Speed, and Time Relationships Vocabulary: Distance vs. Time Graph Vocabulary: Frame of Reference Motion Distance Speed Constant Speed Average Speed Force Friction Mass and Force Calculating Acceleration Due to gravity Weight Gravity Inertia In this section the basic idea of motion is explored. This section characterizes motions in to four basic types: translational, circular, projectile, and rotational. Also, a key point is to understand motion diagrams and be able to make them.

These diagrams are the beginning foundation understanding motion. The graph is a display of the displacement of an object at constant time interval. Then in section two we transfer the motion diagram to a particle model.

These are exactly the same graphs, but the object is now represented in a simpler form of a particle. In the third section we translate the particle diagram to a position versus time graph.

On the x-axis we have displacement of the car in meters or another SI Unit. In the y-axis we have time which is show in seconds. In section four we then transfer the position-time graph to a velocity-time graph. To form the velocity time graph you determine the slope of the line in the position-time graph. This is done by (R2-R1)/(T2-T1)= velocity (meters/seconds).

Introduction- To introduce this activity, ask two student volunteers to stand in front of the classroom to physically demonstrate and discuss the results of each of the following scenarios: 1. Scenario #1: Two students start from the same position at one end of the classroom. One student takes giant-steps while the other takes baby-steps.

Each student takes one step per second. Who gets to the other end of the classroom first?

How many steps are taken? Discuss the results. One student starts behind the other at the same end of the classroom, both walking with equal stride and pace.

Each student takes one step per second. Who gets to the other end of the classroom first? How many steps does each student take? Discuss the results. Ask students to predict the effect of changing the length of stride. Instruct students that they will use Gizmos to learn about the relationship between distance and time. 12 Lesson 1 Motion, Forces and Energy 2.Write Vocabulary for Lesson 1 3.Discovery Education clips on forces, motion and energy 4.

In their notebooks, try their best to explain their walk from their last class to my class. 5.Share/Post on board Weight and Force: 1. Why does everything fall down and what is mass? What is gravity? How much do you weigh?

Development- 1. Distribute Gizmo handout to each group of students 2. Tell students that they will take turns using Gizmos. Students will work in groups of two. One will be the mouse driver and the other the reader/recorder for the group. The 'Mouse Driver' controls the action of the mouse and movement on the computer screen. The 'Reader/Recorder' will read the directions from the activity sheet and record observations while guiding the activity.

Partners should switch roles until all have moved the runner. Demonstrate how to measure the speed of a marble. Video game connections 3.

Airplane connections Part 3: MASS!!!! All objects have mass. What is mass? What is it measured in? Changes motion. Size of acceleration depends on size of force.

Doubling force does what to acceleration Doubling mass does what to acceleration. Show equation force = mass x acceleration (f = ma), say what each is measured in.

Change in weight due to gravity acceleration. Gravity is attractive. The bigger the mass stronger attraction.

Earth is big enough to notice gravity (falling) Weight is the force from f = ma where a is the acceleration due to gravity. Students will measure the speed of a marble by measuring the speed of a marble 10 times.

Allow students to explore the Gizmo by moving and pressing any buttons. Begin the lesson with the Gizmo Warm-up Activity 4.

. Force and Motion: Facts makes the world go 'round. Motion makes the moon go 'round too. In fact, motion makes lots of things go. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying. But motion is so much more. Motion is important to our lives and impacts so many things that we do.

Motion is the changing of position or location. But motion requires a force to cause that change. Let's learn about force and motion and the effects of these physical laws in our world. What is Force? Force is just a fancy word for pushing or pulling. If I push on something or pull on it, then I am applying a force to it.

Force makes things move or, more accurately, makes things change their motion. Two natural forces that we have experienced are the force of and magnetic forces. These two forces act at a distance and do not require direct contact between the objects to function. Gravity produces a force that pulls objects towards each other, like a person towards the ground. It is the force that keeps the Earth revolving around the sun and it's what pulls you toward the ground when you trip. See Science Trek's site on.

Magnetism produces a force that can either pull opposite ends of two magnets together or push the matching ends apart. A magnet also objects made of metal.

Types Of Contact Forces There are 6 kinds of forces which act on objects when they come into contact with one another. Remember, a force is either a push or pull.

The 6 are:. normal force. applied force.

frictional force. tension force. spring force. resisting force Let's investigate how these forces can be seen in our lives. Normal Force A book resting on a table has the force of gravity pulling it toward the Earth. But the book is not moving or accelerating, so there must be acting on the book. This force is caused by the table and is known as the normal force.

You can “see” the normal force in some situations. If you place a thin piece of wood or plastic (a ruler works) so that it is supported by both ends (by books perhaps) and place a small heavy object in the center, the piece of wood will bend.

Of course it wants to straighten out so it exerts an upward force on the object. This upward force is the normal force. You can feel the force yourself if you push down in the center of the piece of wood. The harder you push, the more the wood bends and the harder it pushes back. Applied Force refers to a force that is applied to an object such as when a person moves a piece of furniture across the room or pushes a button on the remote control.

A force is applied. Frictional Force is the force caused by two surfaces that come into contact with each other. Friction can be helpful as in the friction that allows a person to walk across the ground without sliding or it can be destructive such as the friction of moving parts in a motor that rub together over long periods of time. Tension Force is the force applied to a cable or wire that is anchored on opposite ends to opposing walls or other objects. This causes a force that pulls equally in both directions. Spring Force The is the force created by a compressed or stretched spring. Depending upon how the spring is attached, it can pull or push in order to create a force.

Resisting Forces, like air resistance or friction, change motion. Whether the forces actually stop or slow something depends upon your point of view. Air friction makes a leaf travel along in the wind. When you pick up a pencil, it's friction with your fingers that gets the pencil in motion. In each case, the friction makes the two things (like the air and the leaf) move together. What is Inertia? Is actually not a force at all, but rather a property that all things have due to the fact that they have.

The more mass something has the more inertia it has. You can think of inertia as a property that makes it hard to push something around. What is Friction? Is a force that happens when objects rub against one another.

Say you were pushing a toy train across the floor. It doesn't take much effort or force, because the toy is light. Now say you try to push a real train. You probably can't do it because the force of friction between the train and the ground is more intense.

The heavier the object, the stronger the force of friction. Velocity is the speed of an object in one direction. If an object turns a corner, it changes its velocity because it is no longer moving in its original direction.

Newton's Laws of Motion Some consider Sir Isaac Newton to be the greatest English mathematician of his time and perhaps one of the greatest scientists the world has known. According to a story, Newton saw an apple fall to the ground and he figured out that the same force which caused the apple to fall also governed the motion of the Moon and the planets. In 1687 Newton published his three laws of motion in the “Principia Mathematica Philosophiae Naturalis.” His three laws explained how the concepts of force and motion work.

Newton's First Law Newton's first law of motion states: A body in motion tends to remain in motion, a body at rest tends to remain at rest unless acted on by an outside force. So, if an object is moving – its inertia (mass) will tend to keep it in motion, and if something is at rest, its inertia will tend to keep it at rest. From the Goddard Space Center: learn more about. Check out these.

Newton's Second Law Newton's second law of motion states that a force, acting on an object, will change its velocity by changing either its speed or its direction or both. If your basketball goes rolling into the street and is hit by a bike, either the ball will change direction or its speed or both.

It will also be true for the bike. From the Goddard Space Center: learn more about.Here are some. Newton's Third Law The third law is probably the best known of Newton's laws. It states that for every force and action, there is an equal and opposite reaction. This is what causes a cannon to recoil when it fires. The 'kick' from the firing of the ammunition is what makes the cannon jump backwards. From the Goddard Space Center: learn more about.
