force and motion

2. total distance divided by total time s=d/t,
3. forces acting on an object that combine and form a net force of zero ,
4. Distance and direction of an object's change in position from the starting point.,
5. The rate at which velocity changes (speed up, slow down, or change directions),
7. quantities that have both a magnitude and a direction (represented by arrows),
10. A force of attraction between objects that is due to their masses.,
12. The length of a path between two points - how far an object travels,
13. forces acting on an object that combine and form a net force that is not zero,
15. the motion of a falling object when the only force acting on it is gravity,
16. The sum of all forces acting on an object,
17. the speed and direction of a moving object,
18. velocity changing at a constant rate,
20. The tendency of an object to resist a change in motion More mass =more inertia,

1. The rate at which an object is moving at a given moment in time ( at that moment),
6. The opposing push that resists the movement of an object through air.,
8. is a place or object used for comparison to determine if an object is in motion,
9. movement in relation to a frame of reference,
11. the vector sum of two or more vectorsspeed The distance an object travels per unit of time,
14. the force that opposes the movement of two surfaces that are in contact and are moving over each other .
19. SI unit of force,
