Physics

speed=distance/time

Distance=speedxtime

Time=distance/speed

speed has no direction but velocity has a direction.

an incresse in speed is called acceleration

a decrease in speed is called decellration

speed is usually mesured in meters per second

acceleration=change of velocity/Time taken

More physics

The bigger the force the bigger acceleration

a falling object(if we ignore air resitance) will acurately fall at 10m/s squared

termianl velocity depends on your weight, surface area and density of the air

The large a parachute the slower it will go
