Detailed Solution

The above statement is false.
Kinetic energy: "Kinetic energy is the energy associated with the movement of objects. Kinetic energy is directly proportional to the mass of the object (

m

) and to the square of its velocity (

v

).”

K . E . = \frac{1}{2} m v^{2}

Potential energy: “Potential energy is the energy that is stored in an object due to its position or configuration.”

W = mgh

Where

m

is the mass,

g

is the acceleration and

h

is the height.
The energy possessed by a raised hammer is potential energy and not kinetic energy.
Here every point of the hammer is at rest. Therefore, the kinetic energy possessed by the hammer is zero.
Also, the hammer is raised to a certain height. Hence the hammer possesses gravitational potential energy.
Therefore the correct statement would be that the energy possessed by a raised hammer is potential energy.
