Question

A body of mass 5kg is moving With an acceleration of 0.30m/s^2 . calculate the force acting on it in si unit

Answer 1

Provided that:

• Mass of a body = 5 kg
• Acceleration = 0.30 m/s²

To calculate:

• The force

Solution:

• The force = 1.5 Newton

Knowledge required:

↪️ We can calculate the SI unit of force by using the SI units o mass and acceleration. The SI unit of mass is kg and the SI unit of acceleration is m/s² Therefore, the SI unit of force is kg · m/s² that is kg m/s² But to the honour of Sir Issac Newton the SI unit of force becames Newton(N)

Using concept:

• Force formula

Using formula:

• F = ma

Where, F denotes force, m denotes mass and a denotes acceleration

Required solution:

→ F = ma

→ F = 5(0.30)

→ F = 1.5 N

→ Force = 1.5 Newton $\:$

Answer 2

Answer:-

• Mass=5kg
• Acceleration=0.30m/s$^2$

We know that

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \qquad\quad\sf\longmapsto Force=5\times 0.30$

$\\ \qquad\quad\sf\longmapsto Force=1.5N$

Note:-

SI unit of Force is Newton(N)
