100
The definition of Power.
What is the rate at which work is done?
100
Stored energy.
What is potential energy?
100
The law of conservation of energy.
What is energy is neither created nor destroyed.
200
Negative work
What is when the applied force is in the opposite direction of the displacement?
200
The frictional and normal forces increase proportionally.
What is why does the coefficient of friction stay constant?
200
More power in a shorter amount of time.
What is when you have two objects with the same mass moving the same distance?
200
Energy due to position
What is gravitational potential energy?
200
Kinetic energy increases.
What is as potential energy decreases?
300
Speed of the object does not change.
What is if the net work done on the object is zero?
300
Kinetic friction.
What is the friction of two surfaces sliding past each other?
300
The faster the speed.
What is the greater the power?
300
Units for energy
What is Joules?
300
You have or are looking for a height and a velocity.
What is when you use the conservation of energy equation.
400
Normal force is not equal to gravitational force.
What is when work is done on an incline?
400
Friction is dependent on it.
What is type of surface?
400
Is power a vector?
What is no, it is a scalar!
400
How "stretchy" a spring is.
What is the spring constant?
400
Energy is not lost in a collision because it changes to this.
What is transferred to heat, sound, and other types of energy?
500
An example of positive, negative work, and no work.
What is when Trevor is running away from Mr. Dickson and Mr. Dickson catches Trevor and pulls back on him to get him to slow down (negative work) and then picks Trevor up vertically over his head (positive work) and carries him horizontally back to Brewster (no work)?
500
Friction is independent of it (3 things).
