Question

The net force acting on a body of mass $1Kg$ moving with a uniform velocity of $\mathbf{5}\mathit{m}{\mathit{s}}^{\mathbf{-}\mathbf{1}}$

• A. $5N$
• B. $0.2N$
• C. $0N$
• D. none of these

Answer 1

The correct option is C

$0N$

Explanation for the correct answer

(C): $0N$

1. Newton's first law states that the net force acting on the body is zero since it is traveling at a constant uniform velocity.
2. The acceleration of a moving body is 0 if it moves at a constant speed. The body's net force is equal to zero.

Hence The net force acting on a body of mass $1Kg$ moving with a uniform velocity of $5m{s}^{-1}$ is $0N$. Hence option (c) is correct.
