Question

if a body is moving with a uniform speed in a particular direction no force is acting on it true or false explain​

Answer 1

True.

If a body is moving with a uniform speed in a particular direction, no force is acting on it.

This is because the body is moving with a uniform speed, that is, there is no acceleration on the body. This can be explained mathematically as

F = ma (Newton's second law of motion)

Now, acceleration = 0

⇒ F = m(0)

⇒ F = 0

hence, the net force on the body is zero.

It is notable that the net force is zero, that is, all the forces acting on the body equal zero. Even if several force are acting on the body, they are balancing each other.

If a body is moving with a uniform speed in a particular direction no force is acting on it.

$</p><p>\tt{\pink{\underline {\underline {The \: Statement \: Is \: False. }}}}$

This body is moving with a particular speed in a particular direction.

This statement means that the system is balanced i.e, No external force is being applied, considering null friction.

• Acceleration = 0

Hence, for any Mass, there would be no force applied.
