A 0.125 kg frozen hamburger patty has two forces acting on it that determine its horizontal motion. A 2.30 N force pushes it to the left, and a 0.800 N force pushes it to the right. (a) Taking right to be positive, what is its acceleration?

Two identical charges, 2.0m apart, exert forces of magnitude 4.0N on each other. The value of either charge is: (K = 8.9 x10 9 N m2/C2)

Action-reaction forces

The term “mass” refers to the same physical concept as:

A small car meshes with a large truck in a head-on collision.  Which one undergoes the greater change in momentum?

If you push an object twice as far while applying the same force, you do

You throw a ball straight up.  Compare the sign of the work done by gravity while the ball goes up with the sign of the work done by gravity while it goes down.

A difference between electric forces and gravitational forces is that gravitational forces are not affected by 

Two objects move toward each other because of gravity. As the objects get closer and closer, the acceleration of each
