Forms of Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It depends on the object's mass and height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What factors affect potential energy?

Back

Potential energy depends on mass and height.

Front

What are the two types of nuclear energy?

Back

The two types of nuclear energy are nuclear fission and nuclear fusion.

Front

How is potential energy calculated?

Back

Potential energy (PE) is calculated using the formula: PE = mass (kg) × height (m) × gravitational acceleration (9.8 m/s²).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula: KE = 0.5 × mass (kg) × speed² (m/s)².

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass, assuming speed remains constant.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.
