6.PS3.2 Transformation of GPE to KE

Front

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 measured relative to a reference point.

Front

What is kinetic energy (KE)?

Back

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

Front

How does energy transform from GPE to KE when an object falls?

Back

As an object falls, its gravitational potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What happens to a snowboarder's energy as they descend a hill?

Back

The snowboarder converts gravitational potential energy at the top of the hill into kinetic energy as they move down.

Front

At which point does a pendulum have the most kinetic energy?

Back

A pendulum has the most kinetic energy at its lowest point, where its speed is greatest.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more gravitational potential energy it has.

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

How does a roller coaster demonstrate energy transformation?

Back

A roller coaster transforms gravitational potential energy into kinetic energy as it descends, and vice versa as it ascends.

Front

What is the effect of friction on energy transformation?

Back

Friction converts some mechanical energy into thermal energy, reducing the total mechanical energy available for motion.

Front

What is the formula for calculating gravitational potential energy?

Back

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