Definition
Energy
The ability to do work or cause change
Name the type of energy.
Kinetic or potential energy associated with the motion or position of an object
Mechanical Energy
A toaster is plugged into the wall and uses heat to make toast.
Name the energy transformation.
Electrical Energy to Thermal Energy
A ball is sitting at the top of a hill. Does it have more potential or kinetic energy?
Potential Energy
A child playing on an ipad is an example of
Electrical Energy
Force
A push or pull exerted on an object
Name the type of energy.
A form of potential energy that is stored in chemical bonds between atoms.
Chemical Energy
Is hitting a baseball an example of energy transfer or energy transformation?
Energy transfer
Does a plane flying through the air represent potential or kinetic energy?
Kinetic Energy
a helicopter is an example of
Mechanical Energy
Work
Force exerted on an object that causes it to move
Name the type of energy.
The energy transferred through space by electromagnetic waves.
Electromagnetic Radiation
A person chewing a piece of chicken and digesting it.
Name the energy transformation
Mechanical Energy to Chemical Energy
Can the potential energy ever be equal to the kinetic energy?
Yes
sunlight is an example of
Electromagnetic Energy
Power
The rate at which one form of energy is transformed into another
Name the type of energy.
Potential energy that depends on the height of an object
Gravitational Potential Energy
Where would the rest of the energy go if a tennis ball is hit with a racket?
Friction, Into the air
What two types of energy ONLY have potential energy?
Chemical and Nuclear
A bird flying is an example of
Kinetic Energy
Law of Conservation of Energy
The rule that energy cannot be created or destroyed
What three types of energy have both potential and kinetic energy?
Thermal, Electrical, and Mechanical
What is the difference between energy transfer and transformation?
Transfer- from one object to another
Transformation- From one form of energy to another
What is the relationship between potential and kinetic energy?
Potential energy is based on shape and position. Kinetic energy is based on motion. The energy can convert between potential and kinetic energy.
Splitting an atom is an example of
Nuclear Energy
