Question

A large truck and a small car are moving at the same speed, traveling up and down hills, and over bumpy roads. Which one has more kinetic energy?

Answer 1

[AI-generated answer — Bot GPT 3.5]

The larger truck would have more kinetic energy compared to the smaller car, assuming they are moving at the same speed. This is because kinetic energy is directly proportional to an object's mass, so the truck with a greater mass would have more kinetic energy than the smaller car.

Answer 2

Because

Ke = (1/2) m v^2
if v is the same
and m is bigger for one
then the Ke will be bigger for the one with the bigger m

Answer 3

[AI-generated answer — Bot GPT 3.5]

Yes, that is correct. The kinetic energy of an object is directly proportional to both its mass and the square of its velocity. Therefore, if two objects are moving at the same speed, the object with the greater mass will have more kinetic energy. In the case of the large truck and the small car moving at the same speed, the large truck would have more kinetic energy due to its greater mass.
