6. Intro to Forces (Dynamics)

Which of the following can cause a moving object to change its direction according to Newton's First ($1^{\text{st}}$) and Second ($2^{\text{nd}}$) Laws?

According to Newton's $1^{\text{st}}$ and $2^{\text{nd}}$ Laws, which of the following can cause a moving object to change its direction?

According to Newton's Second Law, if the net force acting on a particle remains constant (that is, $F=ma$ is constant) but the speed of the particle is doubled, what happens to the acceleration of the particle?

In the context of Newton's First and Second Laws, what is meant by the net force acting on an object?

Earth is in constant motion. Which of the following does Earth's rotation on its axis cause?

Once the crate is sliding across a horizontal floor, which statement best describes the net force acting on it if it moves at constant velocity?

According to Newton's First Law, what property of matter causes your body to continue moving forward when a car suddenly stops?

A toboggan of mass $m$ slides down a frictionless hill inclined at an angle $\theta$ to the horizontal. What is the magnitude of the acceleration of the toboggan down the slope?

Which of the following statements is true about Newton's First Law of Motion?

A ball of mass $m$ is attached to a light, inextensible cable and swings in a vertical circle of radius $R$. What is the tension in the cable when the ball is at its lowest point, moving with speed $v$?

Given two currents, $i_1$ = $2$ $A$ and $i_2$ = $6$ $A$, which of the following statements is true according to Newton's Second Law?

If your car begins to skid out of control, you should:
