Potential Energy

Question 6 • POP Physics 26/27

Four vehicles are traveling on the same road. Which vehicle most likely has the greatest kinetic energy?

Answer
A
a compact car traveling at a velocity of 10 m/s
B
a pickup truck traveling at a velocity of 25 m/s
C
a minivan traveling at a velocity of 10 m/s
D
a motorcycle traveling at a velocity of 25 m/s

Explanation

Kinetic energy is calculated as KE = ½mv², so it increases with both mass and the square of speed. The pickup truck is likely heavier than the other vehicles, and at 25 m/s it is moving faster than the compact car and minivan. Compared with the motorcycle at the same speed, the pickup truck’s greater mass gives it greater kinetic energy. Therefore, the pickup truck traveling at 25 m/s is the most likely choice.
