6. Intro to Forces (Dynamics)

According to Newton's First and Second Laws, which physical quantity determines a body's resistance to changes in its state of motion, such as acceleration or deceleration, when a force is applied?

When attempting to stop on a slippery road, the best action to take is:

In the figure, a block slides along a path that is without friction. According to $N’s$ First Law, what will happen to the block after it leaves the end of the path?

According to Newton's First and Second Laws, what happens when two objects of different masses experience the same net force?
