A bowling ball is dropped from a building at a height of 30 meters, and its velocity is continually tracked as it falls. Assuming that gravity is the only force acting on the bowling ball, which statement best describes the change in velocity of the falling bowling ball?

• The bowling ball’s velocity would increase continually at a constant rate until it hits the ground, reaching maximum velocity just before impact.

• The bowling ball’s velocity would be slow initially before accelerating to reach maximum velocity halfway down and then gradually slowing until impact.

• The bowling ball’s velocity would decrease continually at a constant rate until it hits the ground, reaching maximum velocity just before impact.

• The bowling ball’s velocity would be fast initially before decelerating to reach maximum velocity halfway down and then gradually slowing until impact.

A researcher has four objects (1, 2, 3, and 4) of different masses and wants to compare the known amount of potential energy at a height of 6 meters with the calculated amount of kinetic energy right before the object hits the ground. The researcher drops each object from a height of 6 meters and measures the time it takes for each object to touch the ground to calculate the kinetic energy. The table shows the collected data. Which object’s kinetic energy data is most likely flawed due to experimental error?

• Object 1

• Object 2

• Object 3

• Object 4

A baseball pitcher holds the ball close to his chest and then moves it behind his head before throwing the ball toward the catcher. He then gets back to the initial position before the next pitch. In which position does the baseball possess potential energy?

• When the ball is held close to the pitcher’s chest.

• When the ball is moving away from the pitcher’s body.

• When the ball is thrown toward the catcher.

• When the ball is thrown away from the catcher.

A student makes a model to show the transformation between kinetic and potential energy. The student releases a marble at the edge of a glass bowl at point A, and the marble travels through points B and C, as shown. Which statement correctly compares the kinetic and potential energy of the marble at different positions?

• The marble’s kinetic and potential energy are highest at point A.

• The marble’s potential energy decreases, and its kinetic energy increases as it moves from point A to point B.

• The marble’s kinetic and potential energy are higher at point B than point C.

• The marble’s potential energy decreases, and its kinetic energy increases as it moves from point B to point C.
