A truck and a car running with same velocity. Which of the two has less kinetic energy?

Open in App

Solution

We know that, Kinetic energy $= \frac{1}{2} m v^{2}$
Thus, kinetic energy is directly proportional to the mass of the object.
The mass of a car is less than that of a truck.
So, a car has less kinetic energy.

Q. A car and a truck are moving with the same velocity of

60 k m / h

. Which one has more kinetic energy ?

(M_{T} > M_{C})

Assertion: If a car and a motorbike are running at the same speed, then the car has greater kinetic energy.

Reason: Kinetic energy is directly proportional to the square of the velocity of the object.

A truck has a mass of $8000 k g$ , a car has a mass of $1000 k g$ and a bike has a mass of $100 k g$ . All of them are moving with the same velocity on a road. Then, the kinetic energy will be highest for the:
