Kinetic Energy:
The energy possessed by a body due to its motion is called …………..energy.
a) potential
b) mechanical
c) kinetic
d) translational
Explanation: mathematically kinetic energy is one half of the product of an object’s
mass ‘m’ and the square of its velocity ‘v’.
Kinetic energy is a ……….quantity.
a) basic
b) derived
c) scalar
d) vector
A moving hammer drives a nail into the wood. It has…………energy.
a) Potential
b) elastic
d) mechanical
d) kinetic
Explanation: A moving hammer possesses kinetic energy as it is in virtue of motion. A moving object can do work. Therefore a moving hammer drives a nail into the wood.
A bullet fired from a gun can pierce a target due to its…………
a) acceleration
b) kinetic energy
c) mechanical energy
d) heat energy
Explanation: The kinetic energy of a body by virtue of its motion is called kinetic energy. A moving object can do work. Therefore a bullet fired from a gun can pierce a target due to its kinetic energy.
