An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

constant motion in a straight line

slowing motion in a straight line

accelerating motion in a straight line

constant motion in an unpredictable direction

friction is a force that acts

opposite to the direction of the motion

in the same direction as the motion

the same direction as the applied force

only objects whose motion is being changed

What is Newton's First Law

An object at rest stays at rest, an object in motion stays in motion.

Every action has an equal and opposite reaction
