An object at rest needs an ______________________force in order to move.

Two forces are pushing on the cart with the SAME force. Which of the following best describes the forces and motion of the cart?

What is the net force?

An object at rest will remain at rest and an in motion will stay in motion until acted upon by an unbalanced force.

The force of attraction acting between all matter

A property of an object that resists changing its state of motion or state of rest.

The rate at which velocity changes with time

A force that resists the sliding or rolling of one solid object over another

The unit of force in the international system of units

The sum of all forces that act upon an object

If a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at a constant speed unless it is acted upon by a force.
