Physics - forces laws of motion

 infomation on the force mass accerleration formula with an example question

HideShow resource information

F=ma

Force=Massxacceleration    Mass= force/ acceleration    

Acceleration= force/mass

Units

Force measured in newtons (N)     Mass measured in kilo grams (kg)

Acceleration measured in metres per second squared (m/s squared)

Example

A car has a mass of 1750 kg and an engine that provides a driving force of 5200N. find the acceleration of the car from rest.

Force= 5200N         a=f/m     a=5200/1750  5200/1750= 3.0m/s squared
