Law of Conservation of Energy Calculations Flashcard

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.

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, 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 energy stored in an object due to its position or configuration, commonly calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

How do you calculate kinetic energy?

Back

Kinetic energy is calculated using the formula KE = 1/2 mv².

Front

How do you calculate potential energy?

Back

Potential energy is calculated using the formula PE = mgh.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).

Front

If an object has a mass of 2 kg and is moving at a speed of 3 m/s, what is its kinetic energy?

Back

The kinetic energy is 9 Joules.

Front

What happens to potential energy when an object is lifted higher?

Back

The potential energy increases as the height of the object increases.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases if velocity remains constant.

Front

What is the relationship between velocity and kinetic energy?

Back

Kinetic energy is proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.
