Question

For an object of mass “m” in motion, its kinetic energy depends on the modulus of its acceleration vector.

(a) True

(b) False

The question was posed to me in unit test.

Query is from Kinetic Energy in section Work, Energy and Power of Physics – Class 11

Answer 1

Correct choice is (b) False

Best explanation: The formula for kinetic energy (KE) is as follows;

KE = (1/2) x m x v^2

v = Velocity of the object

From the formula, we can infer that the kinetic energy is independent of the acceleration of the object and only depends on the objects instantaneous velocity.
