Chapter 7 SM

What is effort? The total force exerted on an object.
The rate of doing work is Power
Work= Force*Distance
Simple Machines help us complete tasks easier
Work out ALWAYS <Work in
Efficiency= Work out/work in*100
Load or Resistance= thing you are moving
Mechanical Advantage= Measure of how the simple machine is multiplying the force
The distance principle is when simple machines compensate lack of power by applying the force over a larger area.
AMA= Actual Mechanical Advantage
A lever is a rigid bar that rests on a pivot point
Rotational Equilibrium When two forces on opposite sides of the fulcrum are equal
Rotational Acceleration When a force on one side of a fulcrum is stronger than the other, it pulls the lever into motion
Axle= a shaft that attaches to a wheel to function as one simple machine
Gear= modified form of wheel and axle
Inclined Plane is like a ramp
To measure MA of pulley system, you can count the pulleys
