1. A person who drives 60 miles in a single hour has an average speed of 60 miles per hour, but the instantaneous speed of the vehicle could vary greatly from one instant to another. 2. A cheetah who is running with speed of 80 miles per hour then it is his instantaneous speed because it is shown as in per hour speed. 3. Suppose you are driving in a car and the speedometer constantly varies; this is because the speedometer gives speed at a particular moment of time.
Instantaneous speed is the velocity of an object at a certain time. For example:- Suppose you are driving in a car and the speedometer constantly varies; this is because the speedometer gives speed at a particular moment of time. An object's instantaneous speed is what its speedometer would read at that instant-if it had one. As the previous example shows, average velocity and instantaneous velocity are not the same-they are related, but the relationship is not simple-minded. Definition: When the speed of an object is constantly changing, the instantaneous speed is the speed of an object at a particular moment (instant) in time. The instantaneous speed of an object is defined as the speed of the object at any given instant. To understand the concept of the instantaneous speed, we will look at the table given below which is showing the speed of a car. It shows your speed at a particular instant in time. The instantaneous speed of an object is not to be confused with the average speed. Average speed is a measure of the distance traveled in a given period of time; it is sometimes referred to as the distance per time ratio. Suppose that during your trip to school, you traveled a distance of 5 miles and the trip lasted 0.2 hours (12 minutes). Full Answer. The instantaneous speed of an object should not be confused with the average speed. For example, a person who drives 60 miles in a single hour has an average speed of 60 miles per hour, but the instantaneous speed of the vehicle could vary greatly from one instant to another. Average speed is a measure for distance traveled in a given time frame, often referred to as the distance per time ratio. The moving object has both velocity and speed. The scalar quantity speed is the distance travelled with respect to time. It shows how fast an object is moved. Instantaneous speed is the motion rate of object at a particular time period or moment. If we take an example of a cheetah who is running with speed of 80 miles per hour then it is his instantaneous speed because it is shown as in per hour speed.
