Types of Heat Transfer Concepts

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, an object at a height has gravitational potential energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.

Front

How does a fan work in terms of energy transformation?

Back

A fan transforms electrical energy into mechanical energy to create airflow.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases because kinetic energy is directly related to the square of its velocity.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

At which point in a pendulum's swing is kinetic energy at its maximum?

Back

Kinetic energy is at its maximum at the lowest point of the pendulum's swing.

Front

What is an example of energy transformation in a swinging pendulum?

Back

In a swinging pendulum, potential energy is transformed into kinetic energy as it swings down and back into potential energy as it swings up.

Front

What is the role of friction in energy transfer?

Back

Friction converts kinetic energy into thermal energy, causing energy loss in mechanical systems.
