If the resultant force on an object is not zero, the object will
accelerate in the direction of the resultant force
The bigger this resultant force, the larger the acceleration
For a given force, the greater the object's mass, the smaller the
acceleration experienced
This can be expressed in the form:
F = ma
Where:
F = resultant force on the object, measured in newtons (N)
m = mass of the object, measured in kilograms (kg)
a = acceleration of the object, measured in metres per second squared
(m/s2)
The acceleration occurs in the same direction as the resultant force
