Forces

3. Force = mass x acceleration
5. the scientific law that states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force
10. the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
11. the powerful attractive force that binds protons and neutrons together in the nucleus
13. a powerful attractive force that acts over a short range, responsible for radioactive decay
15. the combination of all forces acting on an object
17. the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
18. the force that opposes the motion of one surface as it moves across another surface
19. A push or pull

1. the attractive or repulsive force between electric charges and magnets
2. the scientific law that states that every object in the universe attracts every other object by mass and distance
4. friction that occurs when an object rolls over a surface
6. friction that acts on objects that are not moving
7. A force of attraction between objects that is due to their masses
8. opposes the motion of an object through a fluid
9. the fluid friction experienced by objects falling through the air
12. "If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object."
14. a unit of force equal to the force that imparts an acceleration of 1 m/sec/sec to a mass of 1 kilogram
16. friction that occurs when one solid surface slides over another
