Question

1 N is the force which produces ______.

Options

• an acceleration of 1 cm s² on a body of mass 1 g

• an acceleration of 1 cm s² on a body of mass 1 kg

• an acceleration of 1 m s⁻² on a body of mass 1 g

• an acceleration of 1 m s⁻² on a body of mass 1 kg

Answer 1

1 N is the force which produces an acceleration of 1 m s⁻² on a body of mass 1 kg.

Explanation:

According to Newton’s second law,

F = ma

So,

1 N = 1 kg × 1 m s⁻²

Therefore, 1 newton is the force that produces an acceleration of 1 m s⁻² in a body of mass 1 kg.
