Forces

2. Forces always occur in _____________________
5. A model that shows the forces acting on an object
9. The force of gravity acting on an object
10. An object in motion stays in motion, an object at rest stays at rest, unless acted upon by an outside force
13. An objects resistance to change in motion
14. In a/an _____________________ collision, then there is no loss of kinetic energy in the collision
16. The scientist is actively choosing to change this in the lab experiment
18. Every action has an opposite an equal reaction
19. Mass times veolcity

1. The only force acting on the object is gravity
3. The amount of matter that makes up a material
4. A curved path followed by an object that is projected near the surface of Earth
6. If I increase the ________________________ between two objects then I will weaken the strength of gravity
7. Two objects with different masses will fall with ________________________ amount of force
8. In a/an ____________________ collision, then there is loss of kinetic energy in the collision
11. Force equals mass times acceleration
12. If I increase the amount of mass an object has, then I will need to _________________ the amount of force to accelerate the object.
15. Two objects with the different masses will fall at the __________________ time
17. The force that resists motion between objects that are touching
20. Every graph needs what at the top of the page (hint: not your name)
