Forces and Motion Equations
Equation For Ideal Mechanical Advantage
IMA=d in/ d out
Ideal Mechanical Energy=distance from input force to fulcrum/ distance from output force to fulcrum
IMA=R in/ R out
Ideal Mechanical Advantage=Radius of input/ Radius of output
Ideal Mechanical Energy=length of incline/height of incline
Equation For Efficiency
Efficiency=Output work/Input work x 100
Equation For Mechanical Advantage
Mechanical Advantage=Output Force/Input Force
MA=F out/F in
Equation For Power From Energy
Equation For Momentum
The unit of momentum is the kilogram-meter per second.
momentum=mass x velocity
Equation For Force
Standard unit of force is called the newton (N).
Force=mass x acceleration
Equation For Acceleration
Velocity is expressed in units of meters per second, so standard units for acceleration are meters per second over time, or meters per second per second which is simplified to m/s2
a=v final-v initial/t
acceleration=final velocity-initial velocity/time
Equation For Speed
Speed measured in meters per second or m/s, kilometers per hour or km/h, and miles per hour or mi/h or mph
Equation For Pressure
Pressure is measured in pascals. One pascal is the pressure exerted by one newton of force on an area of one square meter.
Equation For Work
Work=Force x distance
The joule is the standard unit used to measure work.
Equation For Gravitational Potential Energy
Gravitational Potential Energy=mass x gravitational acceleration x height
Gravity is equal to 9.8 m/s2 at Earth's surface.
Equation For Kinetic Energy
Kinetic Energy=mass x velocity2/2
Equation For Mechanical Energy
ME=PE + KE
Mechanical Energy=Potential Energy + Kinetic Energy
Equation For Power
