Question

When a force of 1 N acts on a mass of 1 kg that is free to move, the object moves with

• A. a speed of 1 m/s
• B. a speed of 1 km/s
• C. an acceleration of $10m/s^2$
• D. an acceleration of $1m/s^2$

Answer 1

The correct option is D

an acceleration of $1m/s^2$

From the second law of motion, Net force = Mass $\times$ Acceleration

$\Rightarrow 1N=1kg\times a$

$\Rightarrow a=1m/s^2$

So, the object has an acceleration of $1m/s^2$
