Forces and Motion Unit 3 Criss-Cross

1. The rate at which an object changes position. Distance / Time.
3. The speed with a direction.
4. The amount of matter in an object.
8. Rate at which velocity changes. Distance / time x time.
10. All objects are attracted to each other by a gravitational force.
12. Where the object changes position to.
14. Forces acting on an object that combine and form a net force of zero.
15. SI units for force
17. Forces acting on an object and form a net force that is not zero.
20. Friction between a surface and a fluid. Example water and air.
21. The combination of all forces acting on an object.
22. A direction you choose as a starting point to describe an object’s position.
23. A push or pull on an object by an objectouching it.
24. an attractive force that exists between all objects that have mass.
25. Opposes the motion of surfaces sliding past each other.

1. Determines how much air resistance the object has.
2. Every object will remain at rest or in a straight line of motion unless acted upon by an external force.
5. How much force is exterted onto an object.
6. The tendency for an object to resist a change in its motion.
7. a force that resists the motion of the two surfaces that are touching.
9. Used to measure mass. 1000 of this unit can make one metric ton.
11. A push or pull on an object.
13. the gravitational force exerted on an object.
16. a force that one object can apply to another object without touching it.
18. Friction between the surface and the air.
19. Prevents surfaces from sliding past each other.
