According to Newton's First Law, what happens to a body at rest or moving with constant velocity if no unbalanced force acts on it?

• It accelerates

• It remains at rest or moves with constant velocity

• It decelerates

• It changes direction

What does the term 'net force' refer to?

• The largest force acting on an object

• The sum of all forces acting on an object

• The force required to keep an object at rest

• The difference between the largest and smallest forces
