Mass
2. Is the distance it travels divided by time it takes
Speed
3. Is speed with direction over rate of motion and the direction
Velocity
4. Is a push or pull, or any action that has the ability to change motion
Force
5. Property of an object that resists change in its motion
Inertia
6. The rate of change in velocity; rate at which your speed increases
Acceleration
7. It is accelerating due to the force of gravity and no other forces are acting on it
Free fall
8. The speed at a pacific time
Instantaneous speed
9. The maximum speed reached by an object in free fall, the speed at which the forces of gravity and air resistance are equal
Terminal speed
10. Whenever one object exerts a force on another, the second object exerts an equal and opposite force on the first
Newton's third law
11. A speed that does not change
Constant speed
12. The action of moving or of changing place or position
Motion
13. The force of attraction on an object on another
Gravity
14. The total distance traveled divided by the total time elapsed
Average speed
15. Two equal forces are applied on an object pushing both ways
Balanced force
16. Forces that produce a non zero net force, which changes an object's motion
Unbalanced force
