6. Intro to Forces (Dynamics)

Which of the following lists the three basic steps in the NSC collision prevention formula as applied to $N{e}^{1}wton’s$ First and $S{e}^{2}cond$ Laws?

According to Newton's First and Second Laws, what happens to the acceleration $a$ of a car in a frontal collision if the net force $F\_\mathrm{net}$ acting on it is large and acts in the opposite direction of its initial motion?

According to Newton's First Law, when an object is in motion and no net external force acts on it, what will happen to its motion?

According to Newton's First Law, an object cannot remain at rest unless which of the following conditions is satisfied?

According to Newton's Second Law, an increase in $F$, not resistance, results in an increase of load.

According to Newton's Second Law, if several objects all have the same mass ($m$) and different net forces ($F\_\mathrm{net}$) are applied to each, which statement is true about their accelerations ($a$)?

Which of the following is an example of an unbalanced force?

If a monkey floating in outer space throws his hat away, the hat and the monkey will both

According to Newton's First Law, will the $velocity$ of a book change as it moves across a surface with no friction and no external forces acting on it?

According to Newton's laws, forces always occur in which of the following ways?

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?
