Dynamics

5. The type of diagram that shows all the forces acting on an object.
6. The force that opposes the motion of two surfaces sliding past each other.
8. The overall force acting on an object after all the forces are combined.
12. The law that states for every action, there is an equal and opposite reaction.
14. The force of gravity acting on an object's mass.
16. The law that states an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a net external force.
18. The force of attraction between two masses.

1. The law that states the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
2. The state in which the net force on an object is zero.
3. A push or pull that can cause an object to accelerate.
4. The type of force that keeps an object moving in a circular path.
7. The pulling force transmitted along a string, rope, or cable.
9. A measure of the amount of matter in an object.
10. The unit of force in the International System of Units (SI).
11. The tendency of an object to resist changes in its state of motion.
12. The force perpendicular to the surface that an object contacts.
13. The type of velocity that is perpendicular to the radius in circular motion.
15. The type of friction that acts on moving objects.
17. The type of friction that acts on objects at rest.
