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)
• The car has more kinetic energy because it moves fast down hills.
The truck has less kinetic energy
• because it has greater mass.
• The truck has more kinetic energy
because it has a greater mass.
The car and truck have the same
kinetic energy.

The correct answer is: **The truck has more kinetic energy because it has a greater mass.**
Kinetic energy is calculated using the formula:
\[ KE = \frac{1}{2} mv^2 \]
where \( KE \) is kinetic energy, \( m \) is mass, and \( v \) is velocity. Since both the truck and the car are moving at the same speed, the one with the greater mass (the truck) will have more kinetic energy.
