![]() ![]() Velocity is considered as a function of displacement, while speed is a function of distance that is travelled.Velocity of a body is the rate at which an object's position changes with a frame of reference and time.A particle of unit mass undergoes one dimensional motion ….A particle moving along x-axis has acceleration ….A particle moves in a straight line with a constant acceleration ….A particle moves along a straight line such that its displacement ….A man throws balls with the same speed vertically upwards ….A car moving with a speed of 40 km/h can be stopped ….A car is moving along a straight road with a uniform acceleration ….A car covers the first half of the distance between two places ….A car accelerates from rest at a constant rate ….A boy standing at the top of a tower of ….A body starts from rest, what is the ratio ….The position x of a particle varies with time ….It is the pace at which distance changes. Speed is defined as the distance travelled by an object in a given amount of time. The displacement of an item in unit time is defined as velocity. Speed refers to the quantitative measurement of how swiftly something moves.Ī moving entity's speed can never be negative. Velocity of a body or an object determines its movement direction. We can now see that, even if the car's speed varies, if it covers the same amount of distance in the same amount of time, its average velocity remains constant. As a result, 20 minutes equals 0.33 hours. We've assumed the car is moving in a straight line for simplicity's sake, and we'll convert all time units to hours. ![]() So, here's how we figure out what Shweta's car's average speed is: Her school is 10 kilometres away, and it takes her 20 minutes to get there, but the speedometer on the dashboard of her automobile always shows a different value. Let's look at an example to help you grasp the difference between instantaneous and average velocity.Įvery morning, Shweta rides in her mother's car to school.
