6. Intro to Forces (Dynamics)

Which of Newton's laws is defined by the equation $F=ma$?

A ceiling fan is rotating at an initial speed of $v=5.0m/s$ at the tip of its blade. The fan is turned off at time $t=0$ and slows down due to friction, experiencing a constant angular deceleration. According to Newton's First and Second Laws, what is the speed of the tip of the blade $10$ seconds after the fan is turned off, assuming no other forces act on it?

According to Newton's First (${\mathrm{Law}}^1$) and Second (${\mathrm{Law}}^2$) Laws, your ability to stop a moving object is affected by which of the following factors?

The airbag in a car inflates and deflates quickly so that during a collision,

If both pulleys in a system are fixed to the shaft and a force is applied to the rope, what is the net acceleration of the pulleys according to Newton's First and Second Laws?

If the forces acting on a moving object are $\mathrm{balanced}$, what will happen to the object's motion?

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

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

A falling object with a weight of $10n$ encounters an air resistance force of $10n$. According to Newton's laws, what is the net force acting on the object?

According to Newton's First Law, what happens to your body when you are in a moving car and the driver suddenly slams on the brakes?
