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)

Responses

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

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

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

1 answer

The correct response is:

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

Kinetic energy is calculated using the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is the mass and \( v \) is the velocity. If both vehicles are moving at the same speed, the one with the greater mass (the truck) will have more kinetic energy.
