), measured in newtons, is defined by:
(1)
Where:
- Mass, measured in kilograms.
- Acceleration, measured in meters per square second.
If we know that 
and 
, then the net force needed to accelerated the ball is:
The force needed to accelerate the ball at 25 meters per square second is 3.5 newtons.
