According to Newton's 1st Law of Motion, what will happen to an object in uniform motion?

• It will change direction randomly

• It will stop immediately

• It will continue moving in the same direction and speed unless acted upon by an external force

• It will increase its speed over time

What does the term 'inertia' describe?

• The ability to do work

• The property of matter by which it retains its state of rest or uniform motion along a straight line unless acted upon by an external force

• The energy lost due to friction

• The force that opposes the motion of sliding surfaces
