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?
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.
Wouldn't that be the change in velocity is negative as shown by the final velocity being negative and the initial velocity being positive which means the difference is negative and time always being positive makes the acceleration constantly negative right, just asking for clarification.
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 :)
+Jack Devin Yes it is. If we say that upwards in the positive direction, then as it is always accelerating down due to gravity then it always has a negative (and constant) deceleration.
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 ??
Difference is because in the first Velocity Time graph the man is moving at a constant velocity. Straight line… however with a ball, it loses energy due to Gravity, so is is not in a straight line. Velocity is constantly decreasing over time, hence highest velocity is at the start.
velocity is a vector, so it has a magnitude and direction. If say a car is going straight it has a positive velocity, if it reverses it has a negative velocity
7 years later and still carrying physics students, thank you
i have to tell that ur an AMAZING teacher. u have no idea how helpful you videos are.
Filzah Mahmood Thank you very much.
Thank you very much sir for the lovely lesson
god bless you
your videos are helpful
This is great help! Thank you!!

That's right

You and Steve are wrong, Mike from Frey siense lessons is better 🤨
@@bilalsolaiman How is acceleartion both pozitive and negative at the same time? Acceleration will constantly remain the same you silly goose!

HOW DID U MAKE THE BATON FALL BACK DOWN LIKE THAT OMG
stop motion u simpleton
Great video! Love the animation too :')
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

THANKS A LOT
At 2:03 don't you mean the total displacement is zero?
3 years later......yes, so anyway how's life

There is no reason for it, you can make whichever direction you like as the positive direction.
becoz jis direction mai accleration us dorection ka force bada aur positive
3:48 why does it have the highest possible velocity at the start ?

Bro just replied to himself 💀
Bro is schrizophrenic lol
Who have exam tomorrow 😢
Have exam today
I don’t understand what a negative velocity is
velocity is a vector, so it has a magnitude and direction. If say a car is going straight it has a positive velocity, if it reverses it has a negative velocity
@@drak1559 oh got it thank you
provide more examples
They will come in time
