Conservation of Energy Quiz

Imagine you're a superhero who can see energy! Can you tell what potential energy is?

• Is it the energy a color-changing chameleon has due to its vibrant colors?

• Or is it the energy a bird perched high on a tree has due to its position?

• Maybe it's the energy a hot cup of cocoa has due to its warmth?

• Or could it be the energy a sprinting cheetah has due to its speed?

Imagine you're in a magical world! Can you tell which of these enchanted objects would have the highest potential energy?

• A spellbook perched on a wizard's shelf.

• A dragon-coaster at the peak of a fairy-tale hill.

• A mystical car parked on a steep hill in the elf town.

• A magical basketball hovering at the top of a giant hoop.

Imagine you're a superhero who can see energy! Can you tell what kinetic energy would look like?

• Would it be the energy an object has because of its unique shape?

• Or the energy an object has because it's really hot or cold?

• Maybe it's the energy an object has because of where it's located?

• Or could it be the energy an object has because it's moving?

Imagine you're a superhero with the power to see kinetic energy. Which of these objects would glow the brightest with kinetic energy?

• A speeding train

• A kid riding a bicycle

• A stationary tree

• A racing car

Imagine you're a superhero who can manipulate energy! Can you tell us the formula you'd use to calculate the potential energy of an object?

• PE = mgh^2

• PE = mg

• PE = mgh

• PE = mgh + 2

Imagine you're a superhero who can calculate the kinetic energy of any moving object in a split second. Can you tell us the formula you'd use?

• KE = mass * velocity

• KE = 1/2 * mass * velocity^2

• KE = 1/2 * mass * velocity

• KE = mass * velocity^2

Imagine you're a super scientist! Can you tell us what the conservation of mechanical energy is all about?

• It's a super principle that says the total mechanical energy of a system decreases when external forces come into play.

• It's a super principle that says the total mechanical energy of a system stays the same, as long as no external forces are messing with it.

• It's a super principle that says the total mechanical energy of a system increases when external forces come into play.

• It's a super principle that says the total mechanical energy of a system doesn't care about any external forces acting on it.

Imagine you're a super scientist! Can you tell us about the law of conservation of energy?

• Energy can be both created and destroyed, just like magic!

• Energy cannot be created or destroyed, only transformed. It's like a shape-shifter!

• Energy can be destroyed but not created. It's a one-way street.

• Energy can be created but not destroyed. It's forever!

Imagine you're a wizard! How would you describe the magical process of energy transformation?

• It's like casting a spell to change one form of energy into another.

• It's like passing my magical energy from my wand to another object.

• It's like storing my magical energy in a magical battery.

• It's like transforming a pumpkin into a carriage, converting matter into energy.

Let's play a fun game! Can you tell me an example of how energy can change from one form to another?

• Does thermal energy turn into sound energy?

• Can chemical energy be transformed into mechanical energy?

• What about electrical energy changing into light energy?

• Or does nuclear energy become electrical energy?
