• 0 J

• 50 J

• 100 J

• 200 J

A 10 kg object has a kinetic energy of 100 J. If a 20 kg object is travelling at the same velocity, what is it's kinetic energy?

• 0 J

• 50 J

• 100 J

• 200 J

A 10 kg object and a 50 kg object are sitting at the same height above the ground. Which of the following is correct?

• The objects have no gravitational potential energy because they are not moving

• The objects have the same gravitational potential energy because they are the same height above the ground

• The 5 kg object has the most gravitational potential energy because mass is inversely proportional to gravitational potential energy

• The 10 kg object has the most gravitational potential energy because mass is directly proportional to gravitational potential energy
