Is change in velocity the same as acceleration?

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.

How does change in direction affect velocity?

Generally,the velocity decreases when a moving object chenges its direction.. this happens because the force is straightforward and by changing the direction it slows down and thus the speed or velocity decreases.

Why does velocity need direction?

The direction of the velocity vector is simply the same as the direction that an object is moving. Note that speed has no direction (it is a scalar) and the velocity at any instant is simply the speed value with a direction.

What is a positive velocity?

A positive velocity simply means that the object is moving in the positive direction, as defined by the coordinate system, while a negative velocity means the object is traveling in the other direction.

What is the opposite of negative thinking?
