Question

caculative examples on force

Answer 1

Force:
A force is a push or pull that can cause an object with mass to accelerate.

Force Formula :
\[F= m \times a \]where,
F = Force,
m = Mass,
a = Acceleration

Force Example:
Case 1: What force is required to accelerate an object having a mass of 4 kg at 7 m/s2?
m = 4 kg, a = 7 m/s2
Step 1: Substitute the values in the below force formula:
\[F = m \times a = 4 \times 7 = 28N\]
Case 2: What would be the acceleration of an object with a mass of 20 kg when hit with a force of 100 N?
F = 100 N, m = 20 kg
Step 1: Substitute the values:
\[F = m \times a \]\[100 = 20 \times a \]\[a = \frac{ 100 }{ 20 } = 5ms^{-2}\]
