Aria, the skilled archer, is preparing for the grand tournament. As she pulls back her bowstring and takes a deep breath to aim, where is the energy stored that will launch her arrow towards victory?
In Aria's hand as chemical potential energy
In the arrow as potential kinetic energy
In the bowstring as elastic potential energy
All of the above
Imagine Scarlett, Michael, and Ava are on a treasure hunt for hidden energy sources. Which of the options below is like a treasure chest of 'stored energy' waiting to be unlocked?
Kinetic energy in a moving cart
Thermal energy between two rubbing hands
Chemical energy in the body

In the ultimate marshmallow showdown, Luna and Aiden are armed with identical slingshots, ready to launch fluffy treats at each other. Luna, being a bit stronger, can pull her marshmallows back further in the slingshot. Who will emerge victorious in this sweet battle, launching their marshmallows with greater velocity, and why?
Luna will win because she can give her slingshot more elastic potential energy
Aiden will win because he is expending less chemical potential energy, and therefore he can give his slingshot more elastic potential energy
Neither, both of their slingshots will provide the same elastic potential energy
They will tie, because the Law of Conservation of Energy states energy cannot be created nor destroyed
Emma and Kai are having a friendly competition to see who can launch a toy car the farthest using a spring launcher. As they pull back the spring and release it, what happens to the spring's elastic potential energy?
EPE increases.
EPE decreases.
EPE remains the same.
Cannot be determined.
Emma is having a blast jumping on her trampoline in the backyard. Right before she springs upwards, the trampoline stretches to about 3 inches from the grass. Then, her dad, Bill, joins the fun. When Bill bounces, the trampoline touches the grass right before he launches into the air. Who has the greatest amount of kinetic energy while in the air, just before touching the trampoline?
Emma
Bill
Imagine Luna and Henry are having a trampoline jumping contest! Which option below best aligns with your reasoning about their jumps?
When Luna jumps, she jumps higher and therefore has more kinetic energy right before touching the trampoline again.
When Luna jumps, the trampoline stretches less, so it has less elastic potential energy and she must conserve more kinetic energy in the air.
When Henry jumps, he has a greater mass and therefore more kinetic energy in the air.
When Henry jumps, the trampoline stretches more, so it has more elastic potential energy, and therefore he must have more kinetic energy right before touching the trampoline again.
