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 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 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 given by the formula \( KE = \frac{1}{2} mv^2 \), where \( m \) is the mass and \( v \) is the velocity. Since the truck has a greater mass than the car and both are moving at the same speed, the truck will have more kinetic energy.
