Energy Types
An object in motion possesses this type of energy.
What is kinetic energy?
What is a Joule (J)?
The SI Unit of power is this.
What is a Watt (W)?
The Work-Energy theorem states that work equals this.
This law states that energy cannot be created or destroyed.
What is the conservation of energy?
This type of energy is stored due to an object's position.
What is potential energy?
Work is defined as this formula.
What is W=Fd?
Power is defined as this.
(Not the formula!)
What is the rate at which work is done?
Kinetic energy does this when work is positive.
What is increases?
Power is work divided by this.
This kind of energy is often created due to friction.
What is thermal energy?
Work is a measure of this.
What is energy transfer?
An engine that does 500J of work in 5s has this much power.
What is 100W?
An object slows down when the work applied to it is this.
What is negative?
Kinetic energy is preserved in this type of collision.
This is the energy you would find in a battery.
What is electric potential energy?
No work is done when the force and displacement vectors (directions) are this.
What is perpendicular?
A 100W bulb uses how this much energy in 4s.
What is 400J?
The amount of work done if a box loses 30J of kinetic energy.
What is -30J?
This is where a car's kinetic energy goes when it skids to a stop.
What is heat due to friction?
This is the energy you would find in gasoline or the food you eat.
What is chemical energy?
The amount of work a person exerts while pushing against a moving box with 50N of force for 5m.
What is -250J?
Student A carries a 50kg backpack up some stairs in 5s.
Student B carries a 25kg backpack up in 10s.
This student is more powerful.
Who is student A?
The speed a 1kg box is moving with after experiencing 6J of work and initially moving at 2m/s.
What is 4m/s?
Twin A runs up a flight of stairs while twin B walks up the same stairs. This twin does more work.
What is neither twin?
