- 3. A force that resists the relative motion of two objects or substances sliding against one another
- 5. An interaction between an object and another object or a field that acts to change the motion of the object
- 7. An encounter between objects in which some of the kinetic energy is converted into other forms of energy
- 8. A property of a moving object; determined by the product of its mass and velocity
- 10. A force exerted over a time interval that causes a change in an object’s momentum
Down
- 2. The rate of change in velocity; speeding up, slowing down, or changing direction
- 4. An encounter between objects in which the total kinetic energy of the objects before and after the collision is equal
- 6. A measure of how much matter is present in a substance
