Question

c. If we increase the velocity of a car
moving on a flat surface to four
times its original speed, its potential
energy ....
(i) will be twice its original energy
(ii) will not change (iii) will be 4
times its original energy (iv) will be
16 times its original energy.
​

Answer 1

Explanation:

moving on a flat surface to four

times its original speed, its potential

energy ....

(i) will be twice its original energy

(ii) will not change (iii) will be 4

times its original energy (iv) will be

16 times its original energy.

Answer 2

Answer:

If we increase the velocity of a car moving on a flat surface to four times its original speed, its potential energy (ii) will not change. Potential energy of a body depends on the mass of the body,acceleration due to gravity, height from the centre of earth.
