6. Intro to Forces (Dynamics)

Which of the following can cause a moving object to change its direction according to $N{1}^{\mathrm{st}}$ and $N{2}^{\mathrm{nd}}$ Laws?

According to Newton's Second Law, why does a heavy object not accelerate more than a light object when both are freely falling in the absence of air resistance?

When reversing direction, you should consider:

A cart is moving at constant velocity on a frictionless track when a switch in the circuit powering its motor is opened, cutting off the force driving the cart. According to Newton's First and Second Laws ($\text{F = ma}$), what will happen to the cart immediately after the switch is opened?

Which of the following is an example of balanced forces?

According to Newton's First Law, balanced forces acting on an object will result in which of the following outcomes?

In the context of Newton's First and Second Laws, what is the primary function of the first stage of a multistage rocket during launch?

According to Newton's Second Law, the magnitude of the block's acceleration reaches its maximum value when the block is subjected to which of the following conditions?

According to Newton's First Law, what will a moving object do when the forces acting on it are balanced ($F=0$)?

According to Newton's First and Second Laws, which of the following is the most effective way to push an object to achieve the greatest acceleration, assuming $m$ is constant and friction is negligible?

Which of the following best describes the difference between balanced forces and unbalanced forces according to Newton's First and Second Laws?

Suppose that $\overrightarrow{v}=0$ cm. Which of the following must be true?

Which of the following best describes Newton's Second Law, often referred to as the basic speed law in physics?
