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 truck has more kinetic energy because it has a greater mass.
The truck has more kinetic energy because it has a greater mass.
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 more kinetic energy because it has a 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.
The correct answer is:
The truck has more kinetic energy because it has a greater mass.
To understand why, we can use the equation for kinetic energy:
Kinetic energy = (1/2) * mass * velocity^2.
In this scenario, both the truck and the car are moving at the same speed. However, since the truck has a greater mass, according to the equation, it will have more kinetic energy. This is because mass is directly proportional to kinetic energy.
