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 car and truck have the same kinetic energy.
The car and truck have the same kinetic energy.
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 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 the truck has more kinetic energy, let's break down the concept of kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. It depends on two factors: the mass of the object and its velocity (speed).
In this scenario, both the truck and the car are moving at the same speed. However, the truck has a greater mass compared to the car. According to the formula for kinetic energy (KE = 1/2 * mass * velocity^2), the mass plays a significant role in determining the amount of kinetic energy. As the mass of an object increases, its kinetic energy also increases.
Therefore, since the truck has a greater mass than the car, it will have more kinetic energy, regardless of the terrain or the speed at which they are moving. This is because the mass of the truck contributes more to its kinetic energy compared to the car.
