1 thought on “define the following terms <br />a) speed and velocity<br />b) average speed and velocity”
Explanation:
a) Speed can be taken as the rate at which an object overs distance. A fast moving object has a high speed and covers a relatively large amount of distance in a given amount of time, while a slow moving object will be just opposite of this statement. The velocity of an object is the the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object’s speed and direction of motion.
b) Average speed is defined as the total distance travelled by the time taken whereas average velocity is defined as the displacement by the time taken. Average speed is a scalar quantity
