Across
- 1. force that opposes the direction of motion of an object as it slides over a surface
- 4. fluid friction acting an object moving through the air
- 8. the overall force acting on an object after all the forces are combined
- 9. a force that acts between any two masses
- 10. friction force that acts on objects that are not moving
- 11. the constant velocity of a falling object the force of air resistance equals the force of gravity
- 12. the friction force that acts on rolling objects
- 15. the motion of a falling object after it is given an initial forward velocity
Down
- 2. the force that opposes the motion of an object through a fluid
- 3. a measure of the inertia of an object and depends on the amount of matter the object contains
- 5. the force that causes a 1-kilogram mass to accelerate at a rate of 1 meter per second each second
- 6. a force that opposes the motion of objects that touch as they move past each other
- 7. a push or a pull that acts on an object
- 13. the tendency of an object to resist a change in its motion
- 14. the force of gravity acting on an object
