If you were driving at 50 miles per hour to get to a store, you would say that your speed is 50 miles per hours. If you were driving in a circle and ended at the same place, you would say that your velocity is zero, because there was no directional gain. The key to remember is that velocity is a vector, which means there is a directional component.
Velocity includes speed and direction both. It can be defined as the speed in a particular direction or distance traveled by an object in a specific direction per unit time. Where as, acceleration is the rate of speed on which the object travels.
Therefore,speed is a scalar quantity and velocity is a vector quantity. In speed, we take distance ;but in velocity ,we take displacement. Speed is a scalar quantity, and a scalar quantity has magnitude but no direction.
It is a vector quantity that has both magnitude and direction. The corresponding vector quantity of speed is velocity. Though they both seem to be similar on the surface, they actually are quite different from each other. Speed is essentially the rate of change of a particular object. AS per ur current standard these terms may and actually can be quite same but as u advance u shall be able to appreciate how different they can be.
Both are measured by distance over time eg. The speed of an object is defined as the distance it has traveled divided by the amount of time elapsed. The velocity of the object is similar to speed but has one main difference: Thus, the speed of an object can never be negative. This makes it so that there is always a direction attached to the speed. This direction can be noted in many different ways. This way, the direction is specified as 45 degrees. Quick Answer Speed is how fast an object is moving.

A point on a circle 16 cm from the center moves through an angle of degrees in 1 min. What is the linear Velocity of the point in centimeters per second? #2.)Status: Resolved.
Come here for homework help in most any field. We will not do it for you, but we can give you hints. Negative velocity means that an object is moving in the direction opposite to sign convention. Suppose we take rightwards as positive, when an object moves towards the left, it has negative velocity. Mar 11, · Homework Help: Velocity homework Mar 10, #1. Sesquipedalian.
