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