Potential and Kinetic energy

Front

What is gravitational potential energy?

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

At which position does a child on a swing have the most gravitational potential energy?

Back

At the highest point of the swing, which is position Z.

Front

What happens to gravitational potential energy as an object falls?

Back

As an object falls, its gravitational potential energy decreases while its kinetic energy increases.

Front

What is kinetic energy?

Back

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

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

At which point on a roller coaster is the gravitational potential energy the greatest?

Back

At the highest point of the roller coaster, which is position W.

Front

Where is the least amount of potential energy found?

Back

At the lowest point of the object, which is typically position C.

Front

If two cars have the same mass, how does speed affect their kinetic energy?

Back

The car with the higher speed has more kinetic energy.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as height increases, assuming mass remains constant.

Front

What is the formula for calculating gravitational potential energy?

Back

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