Question

Does a energy transformation happen when you drop your pencil

Answer 1

Energy transformation does happen when you drop a pencil.

The Energy turns from potential energy in your hand to kinetic energy as it drops and back to potential energy when it hits the ground.

Answer 2

Yes, a energy transformation happens when you drop your pencil.

Which type of energy the pencil has when you drop it?

There are two types of energy the pencil has when you drop it.

1. Potential energy
2. Kinetic energy

What is potential energy?

• The energy possesses by a body because its position.
• The higher the position is from earth's surface the more potential energy it will have
• Similarly the lower the position the potential energy also will be lower.

What is kinetic energy?

• The energy possesses by a body because of its velocity.
• The more the velocity , there will be more kinetic energy.
• The lower the velocity , there will be less kinetic energy.

How the energy transformation occurs when we drop a pencil?

1. When the pencil is on hold at certain height , it will have some potential energy.
2. When we drop the pencil , it will start moving downwards due to earth's gravitational force .
3. As it goes downwards it the pencil will start loosing potential energy and will gaining kinetic energy .
4. When it will hit the floor , again it will loose its kinetic energy and will have potential energy.

So, the energy transformation will happen like ,

    potential energy → kinetic energy → potential energy

This is how a energy transformation happens when you drop your pencil.
