Types of Energy
Energy due to motion
What is kinetic energy?
Energy that an electric current carries
What is electric energy?
A pot of water is boiling, explain where you would see convection, conduction, and radiation within this example.
Convection- hot air bubbles create a current, heat disperses through the fluid until all particles have the same temperature
Conduction- heat travels through the metal pot until all of the surface is heated, water comes in contact with the pot
Radiation- thermal energy travels through the space in the form of fire and electromagnetic waves, heating the pot
What is kinetic energy?
Motion
A ball is thrown into the air, then falls to the ground
What is kinetic energy to gravitational potential energy ?
energy stored in the nucleus of an atom
What is nuclear energy?
Energy that sound carries
What is sound energy?
What types of energy can be both kinetic and potential?
What is electric and mechanical?
I drink preworkout then use an exercise machine at the gym.
What is chemical potential energy to mechanical KE?
The nutrients in the preworkout are broken down to give me energy, then I produce a force to move the parts of the machine
A space heater is turned on and produces heat
What is electric energy to thermal energy?
stored energy
What is potential energy?
DAILY DOUBLE
The sum of kinetic and potential energy of the particles in matter due to random motion
What is thermal energy?
What form of thermal energy transfer does NOT require the presence of matter to transfer heat?
What is radiation?
A planter hangs from a hook above the floor. The hook breaks and the planter falls to the floor.
What is gravitational potential energy to kinetic energy?
Photosynthesis
What is radiant (light energy) to chemical energy (glucose)?
energy carried by electromagnetic waves
What is radiant energy?
Energy stored in the bonds between atoms
What is chemical potential energy?
True or False:
Energy can be created by applying a force to an object
False!
Energy cannot be created or destroyed, it can only be transferred
You hit a drum head with a drum stick and hear a noise.
What is mechanical KE to sound energy?
You eat food and then go for a bike ride. The bike moves forward as you apply force to the pedals. The friction between the brakes and the wheel causes you to stop.
What is chemical energy to kinetic (mechanical energy) to thermal energy?
The total energy of an object or group of objects due to large-scale motions and interactions
Energy stored when an object is stretched or compressed
What is elastic potential energy?
The transfer of energy to an object by a force that makes the object move in the direction of the force.
What is work?
work is only being done while the force is applied to the object
You turn on your dishwasher and run a full cycle.
What is electric energy to thermal energy?
There is also mechanical KE present after electric energy, due to the motion of the washers and water itself.

What is sound energy to electric energy to radiant energy to sound energy?
