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?(1 point)

Question

Responses

The car has more kinetic energy because it moves fast down hills.
The car has more kinetic energy because it moves fast down hills.

The car and truck have the same kinetic energy.
The car and truck have the same kinetic energy.

The truck has less kinetic energy because it has greater mass.
The truck has less kinetic energy because it has greater mass.

The truck has more kinetic energy because it has a greater mass.
The truck has more kinetic energy because it has a greater mass.

Answer 1

The correct response is:

The truck has more kinetic energy because it has a greater mass.

Kinetic energy (KE) is calculated using the formula: $KE=\frac{1}{2}m{v}^2$, where $m$ is mass and $v$ is velocity. Since both the truck and the car are moving at the same speed but the truck has a greater mass, it will have more kinetic energy.
