Motion and Forces
Work and Energy
Work=Force * Distance (W=Fd)
Gravitational Potential Energy= mass
gravitational acceleration
height (GPE= mgh)
Mechanical Energy= Potential Energy + KInetic Energy (ME= PE+KE)
Kineric energy= mass* velocity ^2 /2 (KE= 1/2 mv ^2
Power= Work/ time (P=W/t)
Power= Energy/time (P=E/t)
Machines
Mechanical Advantage= Output force/ Input force (MA=^F out/ ^F in)
Effiency (%) =)Output work/input work) *100
Effiency= )540 J/ 600 J) *100=90%
Ideal Mechanical Advantage= length of incline/ height of incline ( IMA=l/h)
Ideal Mechanical Energy= Radius of input/ Radius of output (IMA= ^R in/ ^R out)
distance from input force to fulcrum/ distance from output force to fulcrum (IMA= ^d in/ ^d out)
Motion
Speed= Distance/time (S=d/t)
Tme=Distamce/Speed (t=d/S
acceleration=final velocity-initial velovity/ time (a=^V final-^V initial/ t
Forces
Force=mass*acceleration (f=ma)
Acceleration=force/mass (a=fm)
Momentum=mass * velocity (p=mv)
Gravity, Friction, and Pressure
Pressure= Force/Area (P=F/A)
