Work, Power & Energy

Work

100

This is multiplied by force to find work. 

What is distance/displacement?

200

This is the unit that Work is measured in.

What is a Joule (J)/What are Joules (J)

300

This is done when the direction of displacement and the direction of the force applied are in the DIFFERENT DIRECTION.

What is loss/energy removed?

400

Friction and drag usually cause this in open systems.

What is loss?

500

The amount of work that will be done when direction of the displacement and the direction of the force are PERPENDICULAR TO EACH OTHER.

What is 0 Joules?

Power

100

Running up a hill requires more of this than walking up a hill. 

What is Power?

200

This is the unit that power is measured in blank.

What is Watts

300

This happens to power when you increase the amount of work done.

What is increasing your power, increasing the power, increasing power

400

This happens to power when you increase time.

What is decreasing power, decreasing your power, decreasing the power

500

If I do 2000 Joules of work in 5 seconds, I produce this amount of power.

What is 400 watts.

PE

100

This is the amount of stored energy in an object based on it's height (equal to m*g*h)

What is Gravitational Potential Energy (GPE)

200

This describes how stretchy/stiff a spring is.

What is k/the spring constant?

300

The quantity is represented by x in the EPE equation. 

What is the amount a spring is stretched or compressed/displacement?

400

Before an object begins to move, the Total Mechanical Energy an object has is equal to its blank

What is Potential Energy (or GPE+EPE)?

500

Energy is neither lost nor gained in this type of system. 

What is a closed system?

KE

100

This is the amount of energy an object has while moving or Blank = 1/2*m*v^2

What is Kinetic Energy

200

This is the unit that Kinetic Energy is measured in.

What is a Joule/what are joules.

300

If I double an objects velocity, I do this to my kinetic energy.

What is quadruple Kinetic Energy /KE becomes 4 times as big.

400

A pendulum is swinging back and forth. As the pendulum moves from its lowest point to its highest point, its energy transfers from Kinetic Energy to this type of energy.

What is Gravitational Potential Energy

500

A hot wheels car is moving down a ramp with friction. The potential energy the car started with is now these types of energy.

What is Kinetic Energy and Thermal/Heat Energy

Conservation/ Transformation

100

This states that energy cannot be created or destroyed, it can only be transferred or change forms.

What is the Law of Conservation of Energy/Energy Conservation?

200

This type of energy increases when there is friction.

What is Thermal/Heat Energy

300

An object falls from a height h with 0 air resistance. The object is at one half (1/2) its original height. The potential energy lost is equal to this energy gained.

What is Kinetic Energy gained.

400

As I lift an object higher I do work on the object. As I do work on the object, the object increases this type of energy.

What is Increasing Potential Energy

500

DAILY DOUBLE EXTENSION PROBLEM!!!!!!!! The equation ∆PE = ∆KE shows how energy may be converted. In the same equation ∆mgh = ∆1/2*m*v^2, this property of the object cancels out in PE and KE.

What is mass. This means that the mass of the object does not matter when finding out how much energy is transferred from PE to KE or KE to PE.
