Three friends were talking about energy. They were discussing the differences between potential and kinetic energy. Read what they said and choose who you agree with most.
"I think potential energy is energy of motion and kinetic energy is energy of position."
"I think potential energy and kinetic energy have no differences."
"I think potential energy is energy of position and kinetic energy is energy of motion."
You are looking at a picture of a roller coaster moving down a large hill. You are trying to decide what is happening to the energy as the cart moves. Which answer is correct?
The roller coaster cart is decreasing in potential energy and increasing in kinetic energy.
The roller coaster cart is decreasing in kinetic energy and increasing in potential energy.
The roller coaster cart is losing all of its energy.
The energy transformation that occurs when someone jumps on a trampoline is best described as:
Elastic PE → Motion KE → Gravitational PE
Sound KE → Chemical PE → Motion KE
Motion KE → Chemcial PE → Gravitational PE
Gravitational PE → Elastic PE → Motion KE
What is the Law of Conservation of Energy?
The concept that humans need to conserve energy in order to save the Earth
The concept that when energy is created, it must be conserved in order to sustain life
The concept that when energy is destroyed, the remaining pieces of matter must be saved to create new forms of energy
The concept that when one form of energy is converted to another, no energy is destroyed in the process; energy can neither be created, nor destroyed.
The energy conversion that occurs when your turn on a flashlight is best described as…
Gravitational PE → Chemical PE → Radiation KE
Chemical PE → Motion KE
Sound KE → Chemical PE → Motion KE
Chemical PE → Radiant KE
The Law of Conservation of Energy states that energy cannot be ________ or ________, but it can change from one form to another.
created, destroyed
gravity, force
heat, created
What are the two factors that affect kinetic energy?
time and energy
power and mass
mass and speed
time and work
