Question

what is the force on 40 g object that accelerating 10m/s^2​

Answer 1

Provided that:

• Mass = 40 grams
• Acceleration = 10 m/s²

To calculate:

• Force

Solution:

• Force = 0.4 N

Using concepts:

• Formula to convert g into kg

• Newton's second law of motion that is the formula of force

Using formula:

• 1 g = 1/1000 kg
• F = ma

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

Required solution:

~ Firstly let us convert grams into kilograms, by using suitable formula!

→ 1 g = 1/1000 kg

→ 40 g = 40/1000 kg

→ 40 g = 4/100 kg

→ 40 g = 0.04 kg Therefore, converted!

~ Now let's find out the force, by using suitable formula!

→ F = ma

→ F = 0.04(10)

→ F = 0.04 × 10

→ F = 0.4 N

→ Force = 0.4 Newton
