Example Force Calculation
Example Problem:
A car with a mass of 1,500 kg accelerates at 3 m/s². What is the force acting on the car?
Step 1:  Identify the given values
From the problem, we are given:
•   Mass:  m = 1500 kg
•   Acceleration:  a = 3 m/s²
Step 2:  Write out the formula
The formula for force is:  F = m x a
•   F = Force
•   m = Mass
•   a = Acceleration
Step 3:  Substitute the given values
F = (1500) x (3)
Step 4:  Simplify and solve
In this example no further simplification is needed
F = 1500 x 3 = 4500
Final Answer: 
The force acting on the car is 4,500 Newtons (N).
