Final Lab equations
Motion
speed= distance/time
s=d/t
speed is motion
time= distance/speed
t=d/s
Acceleration= final velocity-inital velocity/time
a=Vfinal-V inital/t
2.2
1.2
1.3
Machines
Mechinacal Advantage= Output force/ input force
MA=f out/ f in
Mechanical Advantage is like applying force
Ideal Mechanical Advantage = Radius of input/ radius of output
IMA= R in/ R out
Ideal Mechanical Advantage= distance from input force to fulcrum/ distance from output force to fulrum
IMA= din/dout
Efficentcy= the atio of output work
efficiency= output work/ input work
5.2
Forces
force=mass x acceleration 2.2
F=ma
2.2
momentum=mass x velocity
p=mv
2.4
work and energy
work= the use of a force to move a object
work=force x distance
w=Fd
4.1
Gravational Poteial Energy = mass x gravital accelaortion x herighy
gpe= sotred energy or energy an obkject has in the postion
gpe=mgh
kenetic energy is energy of motion
kenetic energy = mass x velocity2/2
ke= 1/2mv^2
mechincal energy = energy of motion or energy possed by a object
Mechinacal energy= Potential Energy + Kentic ENergy
ME=PE + KE
power= the rate at what you do your work
power= work / time
p=w/t
power= energy of time

presure= measure of how much force is in an area
pressaure=froce/area
