Energy
The ability to do work or cause change
energy
What are the 3 ways that heat flows?
Convection, Conduction, and Radiation
What is force?
Push or Pull
what is the energy that an object has by virtue of being in motion
Kinetic Energy
What are the two types of Nuclear Energy, and how do they differ?
Fission is where a nucleus splits into smaller fragments, which releases energy.
Fusion is where small nuclei combine to form larger nuclei. This happens in stars.
What is Work?
Anytime you exert force on an object that causes the object to change its motion in the same direction in which you exert the force.
What is the energy an object has resulting from the position or shape of the object
Potential Energy
What is the Equation for Mechanical Energy?
Mechanical=KE+Pe
What is the Equation for Power?
Power=Work/Time
What does the law of conservation of matter state?
That when one object loses energy, the other objects must gain it.
What are two types of Potential Energy
Elastic, Gravitational, and Chemical
What is the energy an object has do to its motion, shape, position or combination of these factors. (The total Potential and Kinetic Energy)
Mechanical Energy
What is Power?
Power is the rate at which work is done. It equals the amount of work done on an object in a unit of time.
What is the formula for Kinetic Energy?
KE=1/2 x Mass x Speed^2
What is the form of energy that travels through space in waves?
Electromagnetic Radiation
What is the Equation for Work?
Work=Force x Distance
