Question

If we increase the velocity of a car moving on a flat surface to four times its original

speed, its potential energy ….

a .will be twice its original energy

b. will not change

c. will be 4 times its original energy

d. will be 16 times its original energy.
​

Answer 1

Answer:

b. Will not change

Explanation:

We have Potential Energy = mgh

Which means, potential energy depends on height of the object from the ground, acceleration due to gravity (g) and mass of the object. It is independent of velocity, so even if velocity changes, potential energy will not change.
