Unit C: Motion and Forces
Chapter 1: Motion
S=d/t
Speed equals distance over time. Time is in seconds, while the standard unit for speed is m/s. distance is in meters.
t=d/S
Time is distance over speed. Distance is usually in meters, miles, or kilometers. Speed is in seconds or minutes or maybe even hours.
a=^vfinal-^vinitial/t
a is acceleration. Acceleration is the final velocity minus the initial velocity over time. The standard units for acceleration is meters per second per second, or meters per second squared. Velocity is expressed in units of meters per second.
Chapter 2: Forces
F=ma
Force is massxacceleration which is kilograms times meters. Newtons are used to meaure force and one newten is 1kg*m/s^2.
a=F/m
Acceleration is force over mass. Mass is in kg and force is in newtons.
m=F/a
mass is force over acceleration. force is in
p=mv
momentum is mass times velocity. mass is in kg, and velocity is in m/s. momentum is kg*m/s
Chapter 3: Gravity, Friction, and Pressure
P=F/A
Pressure is Force over area. Pressure is in pascals, which is N/m^2. Force is in newtons, while area is in square meters.
Chapter 4: Work and Energy
W=Fd
Work is force in newtons times distance in meters. Work is measured in joules.
GPE=mgh
Gravitational potential energy in joules is mass in kg times gravity which is 9.8 m/s squared times height in meters.
KE=1/2mv^2
Kinetic energy in joules is 1/2 of mass in kg times velocity squared in m/s.
ME=PE+KE
Mechanical energy in joules is potential energy in joules plus kinetic energy in joules
P=W/t
Power in watts is work in joules and time in seconds, minutes, or hours.
P=E/t
Power in watts is energy in joules over time.
Chapter 5: Machines
MA=Output force/Input Force
Mechanical Advantage is output force in Newtons divided by input force in Newtons.
Efficiency%=outputwork/inputwork *100
Output work in joules divided by input work in joules times 100 to get percent.
IMA=l/h
Ideal mechanical advantage is length of incline over height of incline.
