Energy
Energy is the ability to cause a change in an object's motion or what?
Position
When you rub your hands together quickly, friction transforms into ______ energy.
thermal (heat)
What is the acronym we learned to remember the types of energy?
M.E.L.T.S.
The kinetic energy of an object depends on its mass or ___________.
speed
Thermal energy is also called heat energy or ____________
Waste energy
The energy of motion is called
Kinetic energy
A gas stove transforms chemical energy from natural gas into _________ energy.
Thermal (heat) energy
Energy stored in objects that are compressed or stretched is called
Elastic potential energy
The gravitational potential energy of an object depends on its weight or ___________
Height (position above Earth's surface)
A radio transforms radiant energy (in electromagnetic waves) into ________ energy that we can hear.
Sound energy
Potential energy is energy that is
stored
A microwave oven changes _________ energy into radiant (light) energy.
electrical
The total amount of kinetic and potential energy in a system is called ___________ energy.
mechanical energy
Due to __________, when two surfaces rub together, some mechanical energy is always transformed into thermal energy.
friction
Chemical potential energy.
The three types of potential energy are elastic potential energy, chemical potential energy, and ____________
Gravitational potential energy
(Long answer) Restate the law of conservation of energy in your own words.
When energy changes form no energy is gained (created) or lost (destroyed).
The energy in electromagnetic waves is called
radiant (light)
(Long answer) Name the force that resists a bicycle's movement when the brakes are applied (two surfaces [brakes/ground] rubbing)and explain how it transforms energy.
Friction resists the bikes movement. Friction transfers all the energy in the system (mechanical energy) into thermal energy.
Energy stored and released in the nucleus of an atom is called __________ energy
Nuclear energy
________ is the transfer of energy that occurs when a force is applied over a distance.
Work
The Law of Conservation of energy states that energy cannot be created or destroyed, it is just transfered or ___________
Transformed (changes form)
Energy due to the motion of particles (atoms) that make up an object
Thermal energy (heat/waste energy)
(Long Answer) Describe the energy change that allows your body to use food for warmth and movement.
The chemical potential energy stored in the chemical bonds in food is released and transformed into thermal and kinetic energy.
(Long Answer) Expalin waste energy, then relate the amounts and types of energy before and after energy transformations.
Waste energy is the thermal energy released whenever energy transforms. Even the energy is released, the Law of Conservation of Energy states that no energy was created or destroyed, so the energy before and after the transformations should be the same.
