Newton's First Law Practice Problems Online

In the absence of friction (or any other kind of dissipation, like wind), a force is needed to make a moving object keep on moving. True or False?

What is the net force required to maintain the movement of a \(5000\text{ kg}\) object moving at a constant velocity of \(2500\text{ m/s} ?\)

An object that is neither accelerating nor decelerating has no net force acting on it. True or false?

If the kinetic friction force acting on a sliding crate has a magnitude of \(200\text{ N},\) how much force must be applied to maintain a constant velocity?

If the forces acting on a body are balanced, then the body \(\text{_________}.\)
