Physics Online - Energy Stores and Transfers Explained with LEGO

Who is Baron von Barren?

• A hero from a 1990s LEGO series

• A villain from a 1990s LEGO series

• A modern LEGO set

• A character from a video game

What is Manna von Barren?

• A small LEGO set

• A character from a book

• A theme park

• A massive LEGO set

What happens to the LEGO set when it reaches the top?

• It transforms

• It crashes down to the ground

• It plays music

• It lights up

What type of energy is initially stored in the person moving the LEGO set?

• Chemical energy

• Thermal energy

• Gravitational potential energy

• Kinetic energy

What happens to the energy as the LEGO set is moved higher?

• It is lost as sound energy

• It is converted into gravitational potential energy

• It turns into light energy

• It remains as chemical energy

What kind of energy is wasted during the process?

• Nuclear energy

• Thermal energy

• Magnetic energy

• Electrical energy

How is the energy transferred from the person to the LEGO set?

• By electrical working

• By chemical reaction

• By magnetic force

• By mechanical working

What can be used to calculate the increase in gravitational potential energy?

• Mass, speed, and time

• Mass, acceleration, and distance

• Mass, gravitational field strength, and height

• Mass, velocity, and height

What happens to the gravitational potential energy as the LEGO set falls?

• It remains constant

• It increases further

• It is completely lost as thermal energy

• It is converted into kinetic energy

At the end of the process, where is all the energy transferred?

• Back into chemical energy

• Into the thermal store of the surroundings

• Into kinetic energy

• It is completely lost
