6. Intro to Forces (Dynamics)

According to Newton's First Law, for a stationary box to begin moving, what type of force must be applied to it?

According to Newton's First and Second Laws, which statement best describes the relationship between $F$ (force) and the motion of an object?

According to Newton's Second Law, under what condition will an object have zero acceleration ($a=0$)?

Two blocks A and B, each of mass $m$, are placed in contact on a frictionless horizontal track. A constant horizontal force $F$ is applied to block A. What is the magnitude of the force that block B exerts on block A?

According to Newton's First Law, due to which property does a body tend to remain at rest or in uniform motion unless acted upon by an external force?

According to Newton's First and Second Laws, the distance required for a vehicle to stop safely depends on which of the following factors?

A simple elevator ride can teach us about Newton's First and Second Laws. When an elevator accelerates upward, what happens to the normal force exerted by the floor on a person standing inside compared to when the elevator is at rest?

According to Newton's Second Law, if an object of mass $m$ is accelerating at a rate $a$, what is the magnitude $F$ of the net force acting on the object?

For an ideal pulley (negligible mass and friction), which of the following can the pulley change?

A person is running on a track. Which of the following forces propels the runner forward?

Why does bending your legs when running enable you to swing your legs to and fro more rapidly?

According to Newton's First Law, what will a baseball that is standing still on a table do if no net force $F\_\mathrm{net}$ acts on it?

According to Newton's Second Law, which force is responsible for causing the acceleration of an object ($F=ma$)?
