What is Acceleration?

What is Acceleration? Does it mean going really fast? Acceleration in Physics is defined as the rate of change of velocity. Acceleration and retardation are discussed with simple everyday examples! Acceleration due to Gravity is analyzed using the motion of a ball. Uniform Acceleration and Non-Uniform Acceleration are compared.

[@theFuture.IITIAN]

You are wrong kid

[@rigidnoir]

Sir thanks, sir. I wanted to study physics with the best visualisation and with concept clarity. Even though the byjus app gives us animation, you teach not with animation but with the real world. And it will also be easier to understand as you are using the objects that we use in daily life to illustrate. I am from a poor background, sir. And I wanted to learn physics like this but in tuitions, they will charge big amounts. sir no words to say your effort for teaching. I love it. Don't stop teaching at any point. You are doing one of the holy jobs on the planet. And answers for the top 3 questions 1) b. 9.80ms^-2 2). 0.5 ms^-2 3). The bee is accelerated because displacement is a speed in single direction or a line. If we take any point in the line we can see that the velocity will be different because the bee is randomly moving round the room. Which in turn affects the velocity. And it may not be accelerated if it's inittial and final position is same. Because, then the displacement will be zero. I was stuck at this chapter for a day. Then I found you. Probably the best find in my life.👍

[@nizamabaddichpally-shivasr4201]

Thanks

[@rajeevsingh69690]

1st answer The value of acceleration of a ball is -9.8m/s² because the ball's speed is decreasing due to earth's gravity. So,it is a case of retardation while when ball is goes down it's speed is increases so that is the case of acceleration. 2nd answer Initial velocity of a car is = 0m/s Final velocity of a car is = 30m/s So, Acceleration = Change of Velocity÷Time a = (v-u)÷t a = (30-0)m/s÷60s a = 30 m/s ÷60s a = 0.5m/s² 3rd answer Bee is randomly moving in a room at a speed of 1m/s. It means bee is not changing it's speed that's why it's speed is constant. But it is changing it's direction because it is randomly moving in a room . So, bee is changing it's direction that means it is changing it's velocity . And Acceleration is a rate of change of velocity so, this is accelerated motion And finally sir you are a great teacher and your explanation are too good

[@pulkit1772]

Answer 1- (b) -9.8m/s^2 Answer 2 - 0.5m/s^2 Answer 3- Yes, it is accelerated motion because bee is flying randomly so it will change its direction, go upward and downward. So in case it is changing its direction chances are that its velocity will decrease, so it is retardation(negative acceleration), if it is coming downward force of gravity is acting on it so it is acceleration. Thank You for such a nice video😊

[@tanushreereddy77]

1. a) 9.8 m/s² 2. Step By Step solution: Car starts from rest so the initial velocity will be zero. 'Reaches' means final velocity or final point... Which is 30 m/s. Time taken is one minute. Acceleration = v-u/t By putting the values the answer will be 0.5 m/s² 3. Room is not long... Since it is moving randomly everywhere, it needs to change its direction. We know that velocity is speed with direction. So change in direction also means change in velocity.. so it is in accelerated motion.

1answer._9.8m/s square 2answer. 0.5m/s square 3answer.acceleration means which an object chages its velocityis called acceleration .means that the bee is moving in a room its acceleration.

You have taken great effort to make us understand the basic concepts. As a father, I was able to understand your explanation and help my daughter to do the same

[@ManochaAcademy]

Glad to hear that.

Ans of q1=-9.8m/sec square Ans of q2=0.5m/sec square Ans of q3=yes. Because acceleration happen when speed or direction of a body change.

[@afzetgrow9474]

2nd answer should be 2 right ? Because 60 can be divided by 30, because 30×2 = 60,,

[@NS-fx2id]

Answers - a) -9.8m/s^2 b) u = 0, v = 30 , t = 1min = 60 s a = v-u/t = 30-0/60 = 0.5m/s^2 c) Yes, because the direction is not same as the bee is flying randomly in any direction and we know that change in direction causes acceleration.

[@Strugedits]

The velocity of the bee is changing and change in velocity causes acceleration 😅 closely same

[@rajesheducationsystem7376]

well explained sir, , , , which camera and all set up u use.. please reply

[@mayankkumar2141]

Sir excellent video 1) 9.8m/s^2 2)0.5m/s^2 3) yes because the bee is flying randomly in any direction and it is the change in the velocity with direction and position

[@gamechanger7410]

Sir bundles of tnks from a years we studying only theory thats why we not understanding clearly,practical work is one of the best work and now my concept become clear to watch this video ,sir you are the great person.May an evil eyes not affected ❤❤❤❤❤❤😊😊🤗🤗🤗
