A 1000-kg black ball and a 1-kg gray ball each have the same acceleration. Which one would have needed more force?

• the 1000-kg ball
• the 1-kg ball
• both will be going the same force
• more information is needed

A train is moving forward at a constant speed. Which of the following is true?

• the net force points backwards
• the net force is zero
• the net force points downward

A man hits a golf ball (0.2 kg) which accelerates at a rate of 20 m/s/s. What amount of force acted on the ball?

• 100 N
• 20.2 N
• 4 N

A bowling ball rolled with a force of 15 N accelerates at a rate of 3m/s/s. What is the mass of the bowling ball?

• 45 kg
• 0.2 kg
• 12 kg
• 5 kg

While the ball is falling,

• its total energy is decreasing
• its total energy is increasing
• its potential energy is increasing and its kinetic energy is decreasing
• its potential energy is decreasing and its kinetic energy is increasing

Before you drop the ball,

• it has only potential energy
• it has only kinetic energy
• it has potential and kinetic energy
• it has no energy
