Motion and Forces
Forces
forces change motion
types of forces
Gravity
Contact Force
Friction
Balanced and unbalacned forces
Newtons second law relates force, mass and acceleration
force=mass x acceleration
f=ma
a=f/m
acceleration=force/mass
forces transfer momentum
Gravity, Friction and Pressure
Gravity is a force exerted by masses
masses attract onr another
friction os a force that opposes motion
friction occures when surfaces slide against each other
pressure depends on force and area
pressure=force/area
p=f/a
work and energy
work is the use of force ot move an object
Motion
Change in position
position can change at differnet rates
S=d/t
t=d/s
time=distance/speed
speed=distance/time
acceleration=final velocity-initial velocity/time
a-vfinal-vinitial/t
Machines
