6. Intro to Forces (Dynamics)

A constant net force acts on an object. Which of the following best describes the object's motion?

According to Newton's First and Second Laws, if a wheel initially rotating clockwise is instead set to rotate counterclockwise with the same magnitude of angular velocity $\omega$, how does this reversal affect the net torque $\tau$ required to bring it to rest in the same amount of time $t$?

According to Newton's First and Second Laws, if an approaching train is near enough to be a danger, what should a person standing on the tracks do to avoid injury?

A $3.0\mathrm{kg}$ object is acted upon by two forces: $F{1}_1$ = $10\to$ $N$ to the right and $F{2}_2$ = $4\leftarrow$ $N$ to the left. What is the magnitude of the object's acceleration?

According to Newton's First and Second Laws, how much damage a shock causes depends on which three factors?

Which of the following can cause a moving object to change its direction: $gravity$, $inertia$, both, or neither?

Which of the following best describes a $\mathrm{newton}$?

According to Newton's First Law, when you change directions or speed too rapidly, the inertia of the vehicle will cause it to become:

According to Newton's First Law, what happens to an object when the net force acting on it is $0$?

Which method will correctly determine whether the forces on an object are balanced or unbalanced?

A block of mass $m$ slides on a frictionless horizontal surface. If a constant horizontal force $F$ is applied to the block, what is the acceleration of the block?

According to Newton's Second Law, how does the direction of the net force $F\_\mathrm{net}$ acting on an object affect its motion?

Which of the following activities performed by a chemist is primarily based on an understanding of Newton's $1^\{ext\{st\}\}$ and $2^\{ext\{nd\}\}$ Laws of Motion?

If a block is moving to the left at a constant velocity, which of the following statements is true about the net force acting on the block?
