Motion

2. A famous physicist who proposed the 3 Laws of Motion.
3. A device that makes life easier by often reducing the force necessary to do the work.
5. This is caused whenever a force is applied to an object and the object moves in the direction of the force.
6. The movement of objects.
8. The measure of how far and in what direction an object has moved from its starting place.
12. How fast an object moves and in what direction it moves from its starting place.
14. Another name for the First law of motion is the Law of _______.
19. Energy is neither created nor destroyed. This is called the Law of ___________ of Energy.
21. For every action there is an equal and opposite reaction. Action/Reaction forces.

1. The amount of force an object has due to the gravity of the Earth.
2. The units used to measure force.
4. A force that acts upon every object, by pulling it to the centre of the Earth. Large bodies being relatively close to one another cause it.
7. The rate at which the speed or velocity of an object changes. Also it is the change in direction of a moving object.
9. The stored energy an object has. Often it is due to its height.
10. A push or a pull.
11. resistance A force caused through the motion of an object that reduces its speed.
13. A device used to measure through the use of dots the speed or acceleration of an object.
15. Force is equal to the mass of the object multiplied by its acceleration.
16. The measure of how far an object has moved. Usually measured in metres.
17. An object will remain at rest unless acted upon by another or unbalanced force.
18. The rate at which an object moves over a distance.
20. The energy associated with movement.
