Work
This is the amount of force applied over a certain distance. (Force x distance)
What is Work?
This the rate at which work is done.
What is Power?
This is the amount of stored energy in an object based on it's height.
What is Potential Energy (PE)?
What is Gravitational Potential Energy (GPE)?
This is the amount of energy an object has while moving. (1/2*m*v^2)
What is Kinetic Energy?
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?
This is the unit that Work is measured in.
What is a Joule? (J)
This is the unit that power is measured in.
What is a Watt?
This is the unit that PE is measured in.
What is a Joule/What are Joules?
This is the unit that Kinetic Energy is measured in.
What is a Joule/What are joules?
This type of energy increases when there is friction.
What is Thermal/Heat Energy?
This is another way to express the unit Newton for force.
What is kg * m/s>2?
This happens to power when you increase the amount of work done.
What is increasing your power?
What is the potential energy of a 15 kg rock if it is sitting on a cliff that is 12 meters high?
What is 1764 J?
If I double an object's velocity, I do this to my kinetic energy.
What is increase Kinetic Energy/KE?
An object falls from a height with zero 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?
The direction of displacement and the direction of the force applied are in the SAME DIRECTION.
What is positive?/What is an unbalanced force?
This happens to power when you increase time.
What is decreasing power?
This type of potential energy is in food and batteries.
What is Chemical Potential Energy?
Imagine a roller coaster at the fair. At which point is its kinetic energy going to be the highest?
What is at the lowest point on the bottom of the hill?
As I lift an object higher I do work on the object. As I do work on the object, the objects increases this type of energy.
What is increasing Potential Energy?
You push on a box with a force of 200 N for 25 seconds but the box does not move. How much work have you done?
What is 0 Joules? (No work)
If I do 2000 Joules of work in 5 seconds, I produce this amount of power.
What is 400 watts?
An object is sitting on a shelf that is 3 meters off of the ground. If its mass is 20 kg what is its potential energy?
What is 588 J?
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?
The KE of an object has a mass of 10 kg if it is rolling downhill at a velocity of 3 m/s. Calculate this problem.
What is 45 Joules?
