Energy Flashcard

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 of an object due to its position or state. It is often associated with gravitational energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

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 type of energy is associated with the movement of molecules?

Back

Thermal energy is associated with the movement of molecules, reflecting the temperature of a substance.

Front

What is electromagnetic energy?

Back

Electromagnetic energy is a form of energy that is reflected or emitted in the form of electrical and magnetic waves that can travel through space.

Front

What is the relationship between mass and kinetic energy?

Back

For two objects with the same mass, the object with greater speed will have more kinetic energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system, representing the total energy of motion and position.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a roller coaster, where potential energy at the top of a hill is converted to kinetic energy as it descends.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves, which can travel through air, water, and solids.

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.
