motion and forces
motion
an object in motion changes position
position describes the location of the object
describing a position
measuring distance
the position of a place or an object is the location of that place or object
motion is a change in position
motion is the change in position over time
describing motion
relative motion
speed measures how fast position changes
position can change at different rates
calculating speed
S=t/d
Speed=distance/time
average speed
distance time graphs
velocity includes speed and direction
velocity
velocity versus speed
acceleration measures how fast velocity changes
speed and direction can change with time
acceleration
a=^vfinal-^vinital/t
acceleration = final veocity-inital velocity/time
forces
force=mass *acceleration
F=ma
gravity friction and pressure
