Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is the process of energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting chemical energy into mechanical energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does a grasshopper convert energy when it jumps?

Back

When a grasshopper jumps, it converts chemical energy stored in its muscles into mechanical energy to propel itself into the air.

Front

What happens to energy when a tennis ball is dropped?

Back

As the tennis ball falls, its potential energy decreases while its kinetic energy increases until it reaches the ground.

Front

What is the role of a wind turbine?

Back

A wind turbine converts the kinetic energy of wind into mechanical energy, which is then transformed into electrical energy.

Front

What is the relationship between day and night on Earth?

Back

Day and night occur due to the rotation of the Earth on its axis, causing different parts of the Earth to be exposed to sunlight.

Front

What is the Southern Hemisphere?

Back

The Southern Hemisphere is the half of the Earth that is south of the equator, where seasons are opposite to those in the Northern Hemisphere.
