Kinetic and Potential Energy Review

Front

What type of energy does a person standing at the top of a ladder have?

Back

Gravitational Potential Energy.

Front

Which has more potential energy: a helicopter hovering high in the air or a helicopter falling quickly?

Back

The hovering helicopter has more potential energy.

Front

At which point in a roller coaster's journey is its potential energy the greatest?

Back

At the highest point (Point Z).

Front

How can kinetic energy be described?

Back

Kinetic energy is energy in motion.

Front

As a boulder rolls from the top of a hill to the bottom, how do its potential and kinetic energy change?

Back

Potential energy decreases and kinetic energy increases.

Front

What is the formula for calculating gravitational potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is kinetic energy and how is it calculated?

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 the total mechanical energy of a system if there are no external forces acting on it?

Back

The total mechanical energy remains constant (conservation of energy).

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height.

Front

How does the potential energy of an object change as it falls?

Back

The potential energy decreases as the object falls.
