Unit 5 Vocab - Braeden Penrose

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
22. The state of an object when it is not in motion
23. Distance and direction of an object's change in position from the starting point.

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
