A large truck in a smaller car, moving at the same speed, traveling up and down hills and over bumpy roads, which one has more kinetic energy
The truck has Less kinetic energy because it has a greater mass
The car and truck have the same kinetic energy
The truck has more kinetic energy because it has a greater mass
The car has more kinetic energy because it moves fast down hills
What is the correct answer?
The correct answer is: The truck has more kinetic energy because it has a greater mass.
The correct answer is: The car and truck have the same kinetic energy.
Kinetic energy is determined by both mass and velocity. In this scenario, although the truck has a greater mass, it is stated that the truck and the car are moving at the same speed. Therefore, since both vehicles have the same speed, they will have the same kinetic energy.
The correct answer is: The truck has more kinetic energy because it has a greater mass.
To understand why, let's start by defining what kinetic energy is. Kinetic energy is the energy an object possesses due to its motion. It depends on two factors: mass and speed. The formula for kinetic energy is KE = 1/2 * mass * velocity^2.
In this scenario, both the truck and the car are moving at the same speed, so speed does not change. However, the truck has a greater mass than the car. Since mass is directly proportional to kinetic energy, the larger mass of the truck means it will have more kinetic energy compared to the car.
Therefore, the truck has more kinetic energy because it has a greater mass.
