Question

The ratio of speed to the magnitude of velocity when the body is moving in one direction is

Answer 1

Average velocity is defined as ratio of linear displacement of an object by time taken. velocity, average velocity are vector quantities, that means they have both magnitude as well as directions. Displacement can be positive , negative as well as zero based on the direction in which the object is travelling.

Answer 2

Answer:

Concept:

The magnitude of velocity is called velocity, and  the magnitude of the slope of the displacement vs. time plot indicates velocity. As the gradient increases  from A to B, the velocity between points A and B increases. The speed ratio is the ratio of the output speed to the input speed (for example, if the gear ratio is 0.5, the output speed will be 0.5  of the input speed).

Given:

The ratio of velocity to velocity magnitude when the object is moving in one direction is:

Find:

Find the ratio of velocity to velocity magnitude  when an object is moving in one direction is:

Answer:

1 or more. When the object is moving in a straight line, the magnitude of the velocity is equal to the velocity. Therefore, the numerical ratio of velocity to velocity is equal to 1.

If the object moves in one direction, the displacement and distance will be equal at the same time interval.

Therefore, the velocity-to-velocity ratio  is equal to 1.
