Across
- 2. Friction a friction force that opposes the motion of an object as it slides over a surface
- 4. the product of an object’s mass and its velocity
- 5. a push or a pull that acts on an object
- 7. Resistance fluid friction acting on an object moving through the air
- 10. Friction a friction force that opposes the motion of an object through a fluid
- 11. the force of gravity acting on an object
- 13. the constant velocity of a falling object when the force of air resistance equals the force of gravity
- 17. the SI unit for force
Down
- 1. Friction a frictional force that acts on rolling objects, caused by the change in shape at the point of rolling contact
- 3. the curved path of an object in free fall after it is given an initial forward velocity
- 6. a force that opposes the motion of objects that touch as they move past each other
- 8. the tendency of an object to resist a change in its motion
- 9. Friction a friction force that acts on objects that are not moving
- 12. the attraction between any two objects because of their masses
- 14. the amount of matter in an object; a measure of the inertia of an object, which depends on the amount of matter the object contains
- 15. Force the overall force acting on an object after all the forces are combined
- 16. of Conservation of Momentum law stating that the total momentum of a system does not change if no net force acts on the system
