This is the Law of the Conservation of Energy
What is Energy cannot be created or destroyed, only transferred or transformed
100
This is the difference between potential and kinetic energy
What is potential energy is energy available and kinetic energy is energy of motion
100
This is the definition of balanced forces
What is when forces are equal in strength but opposite in direction

This energy transformation happens from the battery to the light being given off on a computer screen
What is chemical to electrical to light
200
Between the top of the hill, halfway down the hill and the bottom of the hill, this point has the greatest potential energy
What is the top of the hill
200
This is the definition of unbalanced forces
What is when forces are unbalanced in strength and opposite or the same in direction
200
True or false: at the beginning of the toy's journey, the toy was traveling fast. The slope is steep.
What is false
300
This is the term for resources that cannot be used again because humans use them faster than they can be replenished or cannot be remade at all
What is nonrenewable resources

This energy transformation happens when a hawk eats a mouse and uses the energy from eating the mouse to fly
What is chemical energy to mechanical energy
400
This energy transformation happens as a rock is falling off of a cliff. As ____________ decreases, _______________ increases
What is potential, kinetic
400
True or false: The forces are acting in opposite directions
What is true
400
This ramp needs the least amount of force
What is C
500
This explains the disadvantage of only using nonrenewable resources instead of renewable resources
What is non renewable resources run out. To only use them means that when they run out, humans and Earth will not have them anymore.
