What happens to the movement of an object if there are no external forces acting upon it?

• It keeps moving forever

• It slows down and stops

• It changes direction

• It accelerates

According to Newton's second law of motion, what does the acceleration of an object depend on?

• Mass and velocity

• Force and energy

• Mass and force

• Velocity and energy

If the mass of an object is increased, what happens to the force required to move it?
