Question Bank - General Science

Here's the question bank on all the general science topics.

The Kinetic energy of an object can never be:

A.
Positive
B.
Negative
C.
Zero
D.
Equal to potential energy

Solution:

The correct answer is Negative.Kinetic energy is a function of motion.Consider, that an object that is moving has something that is referred to as kinetic energy. Since kinetic energy is based on motion, it is always a positive value. If it is not in motion, the kinetic energy of that object is zero and it cannot be negative at all.Additional InformationKinetic energy (KE): The energy possessed by a body by virtue of its motion is called kinetic energy.\(KE = \frac{1}{2}m{v^2}\)Where m = mass of the body and v = velocity of the bodyPotential energy (PE): The energy possessed by a body by virtue of its position or configuration is called potential energy.\(PE = mgh\)Where, m = mass of the body, g = acceleration due to gravity, and h = height of the body
