Energy
Ability to do work
What is energy
The energy an object possess by virtue of it's motion.
What is Kinetic Energy?
What is potential energy
What does the Law of Conservation of Energy state?
What is the total amount of energy remains constant in an isolated system.
Chemical, Electrical, Thermal, Mechanical, Gravitational, Nuclear
What is the six forms of energy
Two factors affect kinetic energy?
What is Mass and Velocity
Is an object with potential energy doing work?
What is no.
Where is potential energy the highest?
What is at the top of a roller coaster's biggest hill.
Energy being changed into another form of energy.
What is energy transformation
As velocity increases, what happens to the amount of kinetic energy?
What is increase
P.E. = mgh
What is the formula for potential energy
Where is kinetic energy the highest?
What is the bottom of a roller coaster's big hill.
Mechanical Energy -> Thermal Energy -> Chemical Energy -> Electromagnetic Energy, Thermal Energy
What are the energy transformations that occur in the striking of a match?
As the mass increases, what happens to the amount of kinetic energy?
What is increase
As the distance between the object and the surface of the Earth increases, what happens to the potential energy?
What is it increases.
Where does a golf ball gain it's kinetic energy?
What is when the golf club hits the golf ball.
Car Engine Starting
Electrical Energy -> Electromagnetic Energy, Thermal Energy -> Chemical Energy -> Mechanical Energy, Thermal Energy
Windmills
Wind Energy -> Mechanical Energy -> Electrical Energy
What is two examples of energy transformations.
KE = (1/2)mv2
What is the equation for calculating kinetic energy?
As a wrecking ball is released, what kind of energy does the potential energy transfer to?
What is kinetic energy.
Explain the transfer of potential and kinetic energy as an archer draws his bow.
What is potential energy is at it's highest when the bow is drawn all the way and kinetic energy is at it's highest when the arrow is released.
