Heat It UP
The direction is which thermal energy flows
From warmer objects to cooler objects
Electrical energy is a _______________ energy
Kinetic
The formula for Work
Work= Force x distance or W= Fd
A device with few or no moving parts that is used to perform work
Simple Machine
The work you do on a machine
Work input
The transfer of thermal energy through waves.
Radiation
The flow of electrical energy from one place to another
Electricity
The scientific definition of (mechanical) work is....
a measure of energy transfer that occurs when force causes an object to move a certain distance
Øconsists of two circular objects of different size or a wheel attached to a rod or stick
Wheel and axle
The work done by the machine
Work output
The transfer of thermal energy through circulation of fluids
Convection
All parts of the circuit are connected one after another to form a loop
Series circuit
Work is a measurement of what
energy transfer
a ramp or slope that reduces the force needed to move objects up and down heights
Inclined plane
The amount of help you can get from using a machine to do something instead of just doing it with purely your own strength
Mechanical advantage
The transfer of energy through direct contact
Conduction
The three components of a circuit
Power source, device and wire
A baseball player throws a ball with a force of 10 N. The ball travels 20 meters. What is the total work?
200J
Can be used to lift things, separate things or to hold them together
Wedge
The equation for mechanical advantage is....
Mechanical advantage = output force/ input force
Metal is a good _________________, as it helps energy to flow easily
Conductor
Resistor that better controls the flow of electricity
Potentiometer
The formula for Force
Force= mass x acceleration or F=ma
the Fulcrum is located between the Load and the Force
First Class Lever
What is implied when the mechanical energy is greater than 1
force is multiplied — work is made easier, but slower
