Define the following. distance, speed, velocity, uniform speed, non uniform speed.
Answers
1 Distance : The length of the actual path between the initial and the final position of a moving object in the given time interval is known as the distance travelled by the object. Distance = Length of path I (ACB) Distance is a scalar quantity.
2 Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.
3 The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
4 if an object is traveling in such a way that it covers the same distance for each interval of time it is traveling, then it is said to be traveling with uniform speed.
5 Non-Uniform speed : If a body covers unequal distances in equal intervals of time or equal distances in unequal intervals of time,however small may be the intervals,is called Non -uniform velocity.
