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 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. The truck has less kinetic energy because it has greater mass. The car and truck have the same kinetic energy.
1 answer
The correct response is: The truck has more kinetic energy because it has a greater mass.
Kinetic energy is given by the formula \( KE = \frac{1}{2} mv^2 \), where \( m \) is mass and \( v \) is velocity. Since the truck is larger, its mass is greater than that of the car, and if both are moving at the same speed, the truck will have more kinetic energy due to its larger mass.
