Across
- 4. the acceleration of an object is related to the net force acting on it and the mass of the object: F = ma
- 6. the speed and the direction of motion of an object; also, the rate of change of an object's position over time
- 7. the amount by which the opposing forces acting on an object are unequal
- 8. a force that must touch
- 11. the force that pushes up to support the weight of an object
- 12. the metric unit used to measure force or weight
Down
- 1. a push or pull that causes something to change its speed or direction
- 2. if the forces acting on an object are balanced, the object will continue doing what it is doing
- 3. a force that acts on an object to change its speed or direction from a distance
- 4. for every action, there is an equal and opposite reaction
- 5. a change in an object's speed
- 9. a force that occurs when two things move past each other and rub together
- 10. a force that acts without physical contact to pull two objects toward each other
