GPE & KE Flashcard #2, 23-24, gk

Front

What is Kinetic Energy (KE)?

Back

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

Front

What is Gravitational Potential Energy (GPE)?

Back

Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, calculated using the formula GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the formula to calculate weight?

Back

Weight (W) is calculated using the formula W = mg, where m is mass and g is the acceleration due to gravity.

Front

What is the value of Earth's acceleration due to gravity (g)?

Back

The value of Earth's acceleration due to gravity (g) is approximately 9.8 m/s².

Front

What happens to Kinetic Energy when an object comes to a stop?

Back

When an object comes to a stop, its Kinetic Energy is transformed into other forms of energy, primarily thermal energy (TE) due to friction.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, given a constant gravitational field.

Front

What is the principle of conservation of energy?

Back

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

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact, causing some Kinetic Energy to be transformed into thermal energy.

Front

What is the difference between Kinetic Energy and Potential Energy?

Back

Kinetic Energy is the energy of motion, while Potential Energy is stored energy based on an object's position or state.

Front

How does height affect Gravitational Potential Energy?

Back

Gravitational Potential Energy increases with height; the higher an object is, the more GPE it has, assuming mass and gravity are constant.
