What is Speed? | Motion and Time | Don't Memorise

[@InfinityLearn_NEET]

#DidYouKnow: If you want to find the speed of any object you have to divide the distance it has covered with the time it required. And, the first person to measure speed in this way i.e. calculate distance over time to find speed was the famous Italian astronomer and physicist Galileo Galilei.

[@joenice4146]

love how you guys explain concepts.
But why not time over distance but distance over time.
Waiting for my answer 🙃

[@weiyouxd]

it's like how you say 'frames per second' and not 'seconds per frame'

[@ranughoush7224]

It's because an object is covering a distance 'at a time'. Hence , we say that distance 'over time' .

[@sushmamahesh5178]

To know whether or not an object is moving faster or slower than another object we need to measure their speed
In the two cars simulation in this video, object 1 is moving faster and compare them
And in the blue car simulation the blue car is moving in rectilinear motion and the blue car was moving with bigger speed and its speed is 21m/s

[@neenmendesarmy5811]

At 2:08 it says “we will get this.” Can you be more specific about how do we get the answer? The video is really helpful thank you so much I would really appreciate if you see this comment and respond. ☺️💕

Why we calculate speed with direction is velocity but we know that speed is distance by time and velosity is displasment by time so speed with direction as velosity but it'd distance not displasment do why we calculate like this what's is reason . please solve my confusion.

[@eilennazo]

In the physical plane of existence, our universe has many 'forces' (an interaction that changes the motion when unopposed) as you serve a physical presence in this universe then one can easily conclude that forces will impose an action upon subfamily "Erinacine" and of a shade of blue. As such, perhaps you have the same conclusion as I. You see, we must not resist these forces. Rather, we must use it to our advantage! You may not be aware, but you are in position of a weight-bearing and locomotive anatomical structure we refer to as 'legs'. Truly a blessing. A miracle of life! One must pause to appreciate these wonders , and how we came to be. You legs are capable of converting energy from your organisms energy stores to direct force! Thus resulting in momentum, through the 'inverted pendulum' gait in which you as a carbon based life form are capable of propelling yourself with! But this is not enough! We must exert as much force as possible, converting all available energy sources, and pushing yourself with as much force as possible! You will ache. In summary, you must exert as much force as possible when when you gait, and you must move at the highest velocity your body is capable of so that you can assert the fact that you are the fastest, and speediest thing around. This achievement I have just made a will be mark in our world. Because of this, we will be remembered. Now, life may have some meaning.
