What is gravitational potential energy (GPE)?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as GPE = mass × gravity × height.

Front

Which factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the mass of the object, the height above the ground, and the acceleration due to gravity.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated as KE = 0.5 × mass × velocity².

Front

What two factors determine kinetic energy?

Back

Kinetic energy depends on the mass and velocity of the object.

Front

How does thermal energy transfer occur?

Back

Thermal energy transfers from areas of high thermal energy to areas of low thermal energy.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy is GPE = m × g × h, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is momentum?

Back

Momentum is the quantity of motion an object has, calculated as the product of its mass and velocity.

Front

What two factors affect momentum?

Back

Momentum depends on the mass and velocity of the object.

Front

What is the relationship between height and gravitational potential energy?

Back

As the height of an object increases, its gravitational potential energy also increases.

Front

What happens to kinetic energy when an object's speed doubles?

Back

If an object's speed doubles, its kinetic energy increases by a factor of four, since KE is proportional to the square of the velocity.
