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