Displacement-Time and Velocity-Time Graphs - A Level Physics

This video introduces and explains displacement-time graphs and velocity-time graphs for A Level Physics.

Developing your GCSE knowledge of distance-time and speed-time graphs with your new knowledge of their vector equivalents. Displacement is the vector equivalent of distance and velocity is the vector equivalent of speed. The gradient of a displacement-time graph is equal to the velocity of the object. The area underneath a velocity-time graph is equal to the total displacement of an object. We can also use a velocity-time graph to produce an acceleration-time graph.

Thanks for watching,

Lewis

7 years later and still carrying physics students, thank you

[filzahmahmood]

i have to tell that ur an AMAZING teacher. u have no idea how helpful you videos are.

[lju]

Thank you very much sir for the lovely lesson

[bmbidoll]

HOW DID U MAKE THE BATON FALL BACK DOWN LIKE THAT OMG

[youssefmaklad]

god bless you
your videos are helpful

Hey Steve! Me and my friend have had a disagreement. He is saying that your acceleration time graph is wrong. Is he correct? He is saying that it is nota line but acceleration turns positive when the object starts to fall back down.

[jackdevin]

Firstly, your videos are great and incredibly helpful!
Secondly, I have a little question: For the three graphs drawn at the end, is the object constantly decelerating?

Thanks in advance :)

[samsloan]

it is not its gravity which is the force acting on it to cause it fall back down but the objects weight which is equal to its mass x gravity

[willsonbasyal]

i am always a big fan your videos,
And, got a little question: why do we take the upward velocity as positive most often, even though the ball is being thrown against the direction of gravity?
whay dont we take up wards as negative and downwards as positive ??

[michaellong]

Great video! Love the animation too :')

Hi, how do you convert between a velocity time graph, and a displacement time graph. EG if they give a displacement time graph and say convert it into a velocity time graph, Would I have to calculate the gradient of the displacement time graph then plot a straight line (0 gradient) on the velocity time one?

[mga]

3:48 why does it have the highest possible velocity at the start ?

[samjw]

At 2:03 don't you mean the total displacement is zero?

[Elitea]

I don’t understand what a negative velocity is
