Velocity Def Math

Well the difference between speed and velocity is that speed gives us an idea of how fast an object is moving whereas velocity not only tells us its speed but also tells us the direction the body is moving in. V a v g δ x δ t x f x 0 t f t 0. The speed is constant the direction is constant constant speed means that the object is moving at the same speed or does not go faster or slower.

Average velocity is defined to be the change in position divided by the time of travel.

Velocity def math. Velocity is speed how fast something is moving with a direction. Saying that ariel the dog is running 3 km h westwardsis a velocity. Velocity is a vector quantity velocity is also defined as the distance per unit time i e if s is distance travelled in time t then velocity v s t m sec cm sec ft sec km hr mles hr. The rate of change of position is known as velocity.

To figure out velocity you divide the distance by the time it takes to travel that same distance then you add your direction to it. You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time such as miles per hour or kilometers per hour. We can define speed as a function of distance traveled whereas velocity is a function of displacement. Speed and velocity can be a little confusing for most of us.

The equation or formula for velocity is similar to speed. A velocity is constant if the following two conditions are met. But saying just 3 km h is a speed.
