Energy Skate Park Phet Lab

Front

What happens to the speed of a skater when friction is turned on?

Back

The speed of the skater decreases.

Front

At which height is the skater's potential and kinetic energy about equal?

Back

At 4 meters.

Front

What type of energy turns into thermal energy when friction is present?

Back

Kinetic energy turns into thermal energy.

Front

At which point does the skater have the most kinetic energy?

Back

At point C.

Front

What happens to total energy as an object speeds up?

Back

The total energy stays the same.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object has due to its motion.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or height.

Front

What is the relationship between kinetic energy and speed?

Back

As speed increases, kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for gravitational potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.
