Across
- 1. Friction - a friction force that opposes the motion of an object through a fluid
- 2. - 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
- 4. - the force of gravity acting on an object
- 6. - a force that opposes the motion of objects that touch as they move past each other
- 8. Resistance - fluid friction acting on an object moving through the air
- 10. Motion - the curved path of an object in free fall after it is given an initial forward velocity
- 12. Friction - a friction force that opposes the motion of an object as it slides over a surface
- 13. - the SI unit for force
- 14. - the attraction between any two objects because of their masses
Down
- 1. - a push or a pull that acts on an object
- 3. Friction - a friction force that acts on objects that are not moving
- 5. Velocity - the constant velocity of a falling object when the force of air resistance equals the force of gravity
- 7. Force - the overall force acting on an object after all the forces are combined
- 9. - the tendency of an object to resist a change in its motion
- 11. Friction - a frictional force that acts on rolling objects, caused by the change in shape at the point of rolling contact
