Question

assume the objects listed below have the same velocity. which object has the most kinetic energy?

• a bus
• a car
• a plane
• a bicycle

Explanation:

The formula for kinetic energy is \( KE = \frac{1}{2}mv^2 \), where \( m \) is mass and \( v \) is velocity. When velocity (\( v \)) is the same, kinetic energy (\( KE \)) is directly proportional to mass (\( m \)). Among a bus, car, plane, and bicycle, a plane has the greatest mass. So, with the same velocity, the plane will have the most kinetic energy.

Answer:

a plane
