Forces & Motion

2. The amount of matter “stuff” that is in an object
4. The rate in which an object moves; speed depends on the distance traveled and the time take to travel that distance
9. An object’s change in positions over time when compared to a reference point
10. SI unit to measure a force
11. This is Energy because of an objects position or shape
12. The attraction between any two things made of matter
13. The speed of an object in a particular direction
14. A change in velocity over time
15. This is they Energy of motion
16. The ability to do work
17. When the net force acting on an object is zero which means an object is at rest or moving at a constant rate

1. A property of a moving object that depends on the object’s mass and velocity
3. The force of gravity pulling on the mass of something
5. The tendency of all objects to resist any change in motion
6. When the net force acting on an object is anything but zero, resulting in a change in motion, acceleration or deceleration
7. A push or a pull with a size and direction
8. A force that opposes motion between two surfaces that are touching
10. The sum of all the forces acting on a object
