Question

Which example best represents translational kinetic energy?

a plucked string on a guitar

the moving blades of a ceiling fan

a spinning top

a tuning fork struck on a rubber block

an apple falling from a tree

Answer 1

The correct answer is:

An apple falling from a tree is transitional kinetic energy

Step-by-step explanation:

The energy of motion of a body, according to the work it would do if it were produced to rest. The translational kinetic energy depends on motion through space, and for a determined body of regular mass is equal to the output of half the mass times the intersection of the speed. and translational (the energy due to a motion from one position to another.

Answer 2

Answer: Option (e) is the correct answer.

Step-by-step explanation:

There are three types of kinetic energy which are vibrational, rotational and translational kinetic energy.

A plucked string on a guitar will produce sound and it represents vibrational kinetic energy.

The moving blades of a ceiling fan shows the rotation of blades and it represents rotational kinetic energy.

A spinning top also displays rotation therefore, it represents rotational kinetic energy.

A tuning fork struck on a rubber block will produce sound and it will vibrate. Therefore, it represents vibrational kinetic energy.

An apple falling from a tree shows that apple is linearly falls on the ground therefore, it represents translational kinetic energy.

Thus, we can conclude that an apple falling from a tree is the best example which represents translational kinetic energy.
