Answer 4

As shown below, an object with a mass of 5 kg is moving at a speed of 10 m/s. Another object with a mass of 10 kg is moving at a speed of 5 m/s.

Answer 5

As shown below, an object with a mass of 5 kg is moving at a speed of 10 m/s. Another object with a mass of 10 kg is moving at a speed of 5 m/s. Which of the objects has higher kinetic energy? (1 point) Responses The 5 kg object has higher kinetic energy. The 5 kg object has higher kinetic energy. The 10 kg object has higher kinetic energy. The 10 kg object has higher kinetic energy. The objects have equal kinetic energy. The objects have equal kinetic energy. Both objects have zero kinetic energy.

Answer 6

Which statement best describes the relationship between a baseball’s potential and kinetic energy after it is thrown? (assume the ball travels in a straight line)(1 point) Responses Potential energy does not change, and kinetic energy decreases. Potential energy does not change, and kinetic energy decreases. Potential energy decreases as kinetic energy increases. Potential energy decreases as kinetic energy increases. Potential energy increases, and kinetic energy does not change. Potential energy increases, and kinetic energy does not change. Potential and kinetic energy both decrease.

Answer 7

A student bounces a tennis ball. She drops the ball, and then it bounces back up to her. When does the ball have zero kinetic energy?(1 point) Responses Just after it hits the ground Just after it hits the ground Exactly when it hits the ground Exactly when it hits the ground At the very top of its bounce At the very top of its bounce As soon as she drops it

Answer 8

As shown below, a student places a 500-gram car at point X on a wooden racetrack in an energy transformation investigation. What outcome is most likely if the student uses a 700-gram car instead? (1 point) Responses A 700-gram car would have more kinetic energy at point X and less potential energy at the bottom of the racetrack A 700-gram car would have more kinetic energy at point X and less potential energy at the bottom of the racetrack A 700-gram car would have more potential energy at point X and more kinetic energy at the bottom of the racetrack A 700-gram car would have more potential energy at point X and more kinetic energy at the bottom of the racetrack A 700-gram car would have less potential energy at point X and less kinetic energy at the bottom of the racetrack A 700-gram car would have less potential energy at point X and less kinetic energy at the bottom of the racetrack A 700-gram car would have less kinetic energy at point X and less potential energy at the bottom of the racetrack

Answer 9

In an investigation of potential and kinetic energy, a student stands at the top of a hill and pushes a ball down the hill as shown. How does the potential and kinetic energy of the ball change as the ball rolls down the hill? (1 point) Responses The potential and kinetic energy of the ball both decrease. The potential and kinetic energy of the ball both decrease. The potential energy of the ball increases, and the kinetic energy of the ball decreases. The potential energy of the ball increases, and the kinetic energy of the ball decreases. The potential energy of the ball decreases, and the kinetic energy of the ball increases. The potential energy of the ball decreases, and the kinetic energy of the ball increases. The potential and kinetic energy of the ball both increase.
