Question

1. compared to a laboratory cart at the top of a ramp, a cart at the bottom of the ramp has: a. more energy and less stability. b. less energy and more stability. c. more energy and more stability. d. less energy and less stability.

Explanation:

The cart at the top of the ramp has gravitational - potential energy due to its height. As it moves to the bottom of the ramp, this potential energy is converted into other forms (e.g., kinetic energy and some dissipated as heat due to friction). Also, an object is more stable at a lower position in a gravitational field. So, it has less energy and more stability at the bottom.

Answer:

B. less energy and more stability
