Forces

2. The SI unit for force; the force that causes a 1 kg mass to accelerate at a rate of 1 meter per second each second
6. A force that acts between any two masses
7. The constant velocity of a falling object when the force of air resistance equals the force of gravity
8. A force that opposes the motion of objects that touch as they move past each other
11. Law stating that the total momentum of a system does not change if no net force acts on an object
17. A push or a pull that acts on an object

1. The tendency of an object to resist a change in its motion
3. The friction force that acts on rolling objects
4. The force that opposes the motion of an object through a fluid
5. The curved path of an object in free fall after it is given an initial forward velocity
9. The friction force that acts on objects that are not moving
10. The force of gravity acting on an object; the product of an object's mass and acceleration
12. Fluid friction acting on an object moving through air
13. A force that opposes the direction of motion of an object as it slides over a surface
14. The overall force acting on an object after all the forces are combined
15. The product of an object's mass and its velocity
16. A measure of the inertia of an object and depends on how much matter the object contains
