Energy

Front

What is potential energy?

Back

Potential energy is the energy due to an object's position or condition.

Front

What kind of energy does a rock at the edge of a cliff have?

Back

A rock at the edge of a cliff has potential energy.

Front

Why can't a skater reach the same height after going down a ramp?

Back

Because friction is slowing him down.

Front

What does the law of conservation of energy state?

Back

Energy CANNOT be created or destroyed, only transformed.

Front

Which point has the greatest kinetic energy in a ramp scenario?

Back

The point where the object is moving the fastest, typically at the bottom of the ramp.

Front

What is kinetic energy?

Back

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

Front

How is potential energy calculated?

Back

Potential energy can be calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to energy when an object falls?

Back

As an object falls, its potential energy is converted into kinetic energy.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with mass; it is calculated using the formula KE = 1/2 mv².

Front

What is an example of energy transformation?

Back

When a roller coaster goes down a hill, potential energy is transformed into kinetic energy.
