Across
- 3. The speed and direction of an object at a particular instant
- 5. A force which is applied to an object by a person or another object
- 9. The acceleration of an object is equal to the net force acting on it divided by the object's mass
- 13. A physical quantity that has magnitude but no direction.
- 14. The two equal but opposite forces that exist when two systems act on each other
- 15. The motion of an object toward the Earth because of gravity
- 20. Law stating that the total momentum of a group of objects stays the same unless outside forces act on the objects

Down
- 1. The rate at which velocity changes; calculated by dividing the change in velocity by the change in time.
- 2. Two or more forces that are not equal and opposite of one another; can cause change in motion
- 4. A push or pull that acts on an object
- 6. Two equal forces acting in opposite directions on an object
- 7. The state of motion of an object does not change as long as the net force acting on the object is zero.
- 8. A result of a force moving an object a certain distance.
- 10. A system of objects that are not moving with respect to one another
- 11. Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
- 12. A physical quantity that has both magnitude and direction
- 16. The rate at which work is done
- 17. The constant velocity of a falling object when the force of air resistance equals the force of gravity
- 18. The effect of a force acting on an object over time. Calculated by multiplying mass (m) by the change in velocity (△v).
- 19. Speed in a given direction
- 21. The tendency of an object to resist a change in its motion
- 24. The product of an object's mass and velocity
