6. Intro to Forces (Dynamics)

Which of the following situations is the best example of inertia as described by Newton's First Law?

According to Newton's First Law, what is the term for the tendency of an object to resist a change in its motion?

Ignoring friction and air resistance, what is the acceleration of a $2$ kg object when a constant net force of $10$ $N$ is applied to it according to Newton's Second Law?

According to Newton's First and Second Laws, what causes a moving object to change its direction of motion?

Who described the fundamental laws of motion?

According to Newton's Second Law, why do objects that experience the same amount of force accelerate at different rates?

A salad spinner with a moment of inertia $I$ is spinning with an initial angular velocity ${\omega }_0$. If a constant frictional torque ${\tau }_f$ acts to slow it down, how long does it take for the spinner to come to rest?

According to Newton's First and Second Laws ($F_{\mathrm{net}}=ma$), how do unbalanced forces affect the speed and direction of an object?

According to Newton's Second Law, how do you calculate the net force acting on an object?

A box is being pushed across a frictionless surface by two people. One person pushes to the right with a force of $285 N$, and the other pushes to the left with a force of $185 N$. What is the net force acting on the box?

Which of the following best describes Newton's First Law of Motion?

According to Newton's First and Second Laws ($F=ma$), how does friction affect the motion of an object moving on a horizontal surface?

A box is being pushed across a horizontal surface. If the applied force is $22N$ to the right and the net force acting on the box is $18N$ to the right, what is the force of friction acting on the box?

A ball is shot vertically upward from a compressed-air gun at twice its terminal speed. Neglecting air resistance on the way up, what will be the speed of the ball when it returns to its starting point, assuming air resistance acts only on the way down and the terminal speed is $v_t$?
