Forces and Motion 6th Grade

As shown, students were comparing potential and kinetic energy on a roller coaster diagram. Which statements are accurate conclusions of the potential and kinetic energy of the roller coaster? Select TWO correct answers.

• The roller coaster gains kinetic energy as the carts travel from point C to point D.

• The roller coaster gains kinetic energy as the carts travel from point B to point C.

• As the carts travel in a straight line at point D, the kinetic and potential energy is nonexistent.

• The potential energy is at its greatest at the peak at point A.

• The roller coaster gains potential energy as the carts travel from point A to point B.
