Given: m = 5.0kg
F = 20.0N
Unknown: a = ?
Formula: a = F/m
where in, a = acceleration
F = force
m = mass
Note: Formula for acceleration was derived from the formula of force which is: F = ma
To get the formula follow these steps:
• F = ma ← divide both sides by m
• F/m = ma/m ← cancel like terms
• F/m = a ← formula for acceleration
Solution:
a = F/m
= 20.0N / 5.0kg
= 4m/s²
Note: “m/s²” is the standard unit of acceleration
Final Answer: a = 4m/s²
