6. Intro to Forces (Dynamics)

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?

According to Newton's Second Law, which of the following expressions represents the net force acting on an object?

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?
