Work
Work is a ______ times a ________
What is Force, Distance
This is what is transferred by a force to make an object move.
What is Energy?
This is the type of potential energy a cheeseburger on your plate has.
What is chemical potential energy?
This machine consists of a wheel and axel, string, or rope and is used to lift things.
What is a Pulley?
This is the ratio of output FORCE over input FORCE.
What is mechanical advantage
This affects how much work is done on an object.
What is direction
This is the unit for Energy
What are Joules?
These three things affect Gravitational Potential Energy
What are Mass Gravity and Height?
This simple machine is often used to move large objects on to trucks.
What is an inclined plane?
This is the energy that is produced by stretching a rubber band.
What is elastic potential energy?
This is the unit for Work
What is Joules
This is know as energy of motion.
What is Kinetic Energy?
This type of energy is emitted by the sun
What is Radiant potential energy
This simple machine can be found on the playground and is often called a "teeter totter"
What is a lever?
This is the ratio of output WORK over input WORK of a machine
What is efficiancy?
Applying a force of 25N on an object that moves 3m would result in this much work being done on that object.
What is 75J
This type of energy is also known as GPE
What is Gravitational Potential Energy?
A ball falling through the air has this type of energy until it hits the ground.
What is Kinetic energy
This simple machine is an inclined plane wrapped around a cylinder.
What is a screw?
The law of conservation of energy says this.
What is energy cannot be created or destroyed?
Force applied in this direction will result in no work being done.
What is perpendicular?
These are the 2 things that affect an object's kinetic energy.
What are Mass and Velocity
All of the energies of objects are contained in this and can be as small as a single atom to as large as billions of galaxies..
What is a system?
This simple machine is an inclined plane turned on its side.
What is a wedge?
This type of energy is produced from friction.
What is thermal energy?
