General Science - Physics MCQs


Q.  Which of the following is/are correct about Kinetic energy?

a. Kinetic energy can be positive or negative
b. Kinetic energy is independent of frame of reference
c. Both a and b
d. None of the above


ANSWER: See Answer
 
Kinetic energy of a body is half the product of mass of the body and square of the velocity of the body. K.E = 1/2(mv²) Kinetic energy depends on the frame of reference. Kinetic energy of a body is always positive.
