What Is Thermal Energy
Kinetic Energy of particles
What is a Simple Machine?
A Simple Machine has few or no moving parts Simple Machines make work Easier.
What is Work
Transfer of energy through motion A force must be exerted through a distance.
What is Power
The rate of doing work, to increase power.Increase work done,do work in less time.
What is Energy
Is the ability of an object to cause change
What is HEAT
the amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.
What are Pulleys?
Pulleys are wheels and axles with a groove around the Outside.
what does the amount of work depend on
Amount of applied force,Distance over which the force is applied
What is P=w/t
(Work divided by time)
What is Kinetic energy
energy in the form of motion greater mass more KE
What is Complex Machines
Any machine that is made up of more than one simple machine.
What does a pulley need to function
A pulley needs a rope,chain,or belt around the groove to function properly.
what does W=fd
Force multiplied by distance
What is Watt
s the unit of power or radiant flux in the International System of Units, equal to 1 joule per second or 1 kg⋅m²⋅s⁻³. It is used to quantify the rate of energy transfer
What is Potential Energy
Stored Energy amount depends on position,mass
What is a Screw?
An inclined plane wrapped helically around a wheel and axle.
What are Wheels and Axles?
The wheel and Axle are simple Machines The axle is a rod that goes through the wheel which allows the wheel to turn.
What is Joule
the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
How to increase Power
increase work done,Do work in less time
What is Energy conversation
Process of changing energy from one another
What is a Wedge?
Two inclined planes attached together so that they can separate objects.
What is a Incline Plane
An incline Plane is a flat surface that is higher on one end.Inclined planes make the work of moving easier
What must be done in order to do work
Something has to move,Motion must be in the direction of the force
What is the common unit of power
Common unit is horsepower
List the 6 forms of energy
mechanical,chemical,electromagnetic,Thermal,electrical,nuclear
