Skater Energy and Motion Analysis

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with the height of an object in a gravitational field.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to potential energy as a skater goes down a ramp?

Back

As a skater goes down a ramp, potential energy is converted into kinetic energy, increasing the skater's speed.

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 friction affect a skater's motion?

Back

Friction opposes motion, converting kinetic energy into thermal energy, which can slow down the skater.

Front

What does a taller kinetic energy bar indicate about a skater's motion?

Back

A taller kinetic energy bar indicates that the skater is moving faster.

Front

What is the relationship between potential energy and height?

Back

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

Front

What does it mean if a skater is at maximum speed?

Back

If a skater is at maximum speed, it means all potential energy has been converted to kinetic energy, and they are moving at their fastest.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often resulting from friction or other forms of energy conversion.

Front

How can you determine if a skater will make it over a hump?

Back

To determine if a skater will make it over a hump, compare their potential energy at the start to the potential energy required to reach the height of the hump.
