Across
- 1. the overall force on an object when all the individual forces acting on it are added togetherUnbalanced Force: forces that produce a nonzero net force, which changes an object's motion
- 3. the amount of matter in an object
- 6. A unit of measurement that equals the force required to accelerate 1 kilogram of mass at 1 meter per second, per secondNet Force: the overall force on an object when all the individual forces acting on it are added together
- 11. forces that produce a nonzero net force, which changes an object's motion
- 12. A push or pull on one object by another that is touching it
- 13. the force of gravity on an object at the surface of the planet
- 14. A force exerted toward the center of a curved path
- 15. equal forces acting on an object in opposite directions
- 17. the force that pulls objects toward each other
Down
- 1. The upward force that is applied to objects when they exert a force on a surface
- 2. The tendency of an object to resist any change in its motion
- 4. The maximum speed an object will reach when free-falling through a substance, such as air
- 5. Friction acting upon an object moving through the air
- 7. A force that one object can apply to another without physically touching
- 8. the force that one surface exerts on another when the two surfaces rub against each other
- 9. a push or pull exerted on an object
- 10. the motion of a falling object when the only force acting on it is gravity
- 16. When the net force of an object is zero
