Question

The ratio of speed to the magnitude of velocity when the body is moving in one direction is :??
option a:Less than one.
option b:Greater than one.
option c:Equal to one.
option d:Greater than or equal to one. ​

Answer 1

Answer:

equal to one

Explanation:

when body is moving in one direction then displacement and distance are equal in the same time interval.

So the ratio of speed and velocity is equal to one.

Answer 2

Ratio will be equal to 1.

But why ?

• Speed is calculated as the distance divided by time.

• And velocity is calculated as displacement divided by time.

Now, when object is moving in one direction in a straight line , the displacement (i.e. shortest length between starting and stopping point) and distance (i.e. total path length) are equal.

• Hence, in same time interval, the value of speed and velocity will be same.

$\boxed{ \bf \therefore \: speed : velocity = 1 : 1}$
