physics WL

4. When two objects touch against or rub against each other
6. anything that is capable of changing an object's state of motion
7. the change of momentum of an object when the object is acted upon by a force for an interval of time
8. collision one in which there is no loss of kinetic energy in a collision
9. a vector quantity that is defined as the rate at which an object changes its velocity.
10. a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy and its warm
12. it has this if it is in motion
14. the loss of energy available to do work
15. The inertia or resistance to change of motion

1. an object's change in position
2. the measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement
3. definition mas times gravity
5. collision in which part of the kinetic energy is changed to some other form of energy in a collision
11. the capacity for doing work
13. energy an example of kinetic energy, as it is due to the motion of particles, with the motion being the key
