Why do MCS courses open early?

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

Consider a string with several rocks tied along its length at equally spaced intervals. You whirl the string overhead so that the rocks follow circular paths. Compared to a rock in the middle of the string, a rock at the outer end moves

A hang glider and its pilot have a total mass equal to 120 kg. While executing a 360º turn, the glider moves in a horizontal circle with an 8 m radius. The glider’s speed is 10 m/s. What is the net force on the hang glider?
