List One
1. Energy- the ability to do work
2. Work-the movement of an object when a force is applied
3.Weight-the pull of gravity on an object
4. Force-a push or a pull
5. Motion- a change in position of an object
6. Gravity- a natural force that pulls things towards the Earth's surface
7. Friction-a natural force between all objects that touch, when two objects rub against each other causing a slowing of motion
8. Matter-the material that makes up an object
9. Mass-the amount of material that makes up an object
List Two
1. Aerodynamic- to reduce the effects of friction as an object
2. Air resistances-friction exerted on an object by the air it moves through
3.Kinectic energy-energy of motion
4. Potential energy-stored energy
5. Inertia-the tendency of an object to stay in motion unless an outside force stops it, or for an object to stay at rest unless an outside force is applied
6. 3 Laws of Motion- Sir Isaac Newton's three laws of motion
7. Momentum-the force given to an object by its mass speed
8. Tension-the stored energy in a stretched objects
9. Speed= distance/time
10. Velocity- the speed and direction an object travels in a certain amount of time
11. Speed Graph-a graph showing motion over time
12. Lift-a force that causes an object to move up
13. Thrust-a force that moves an object forward
List Three
1. Acceleration- to increase the rate of speed
2. Deceleration- to decrease the rate of speed
3. Constant- not changing
4. Distance- the length between two points or things
5. Direction- the line or course along which someone or something goes, lies, or points
6. X-Axis- the horizontal axis along the bottom of a speed graph, shows time on a speed graph
7. Y-Axis-the vertical axis along the side of a speed graph: shows the distance traveled
8. Spring Scale- a tool used for determining force
9. Newton- a unit used to measure force
10. Meter stick- a tool used for measuring distances
