For section E when calculating the acceleration would we get a negative number?

[myGCSEscience]

Yes, because velocity has direction and the negative would indicate deceleration or negative acceleration.

[Rushita Amin]

Is this right : A horizontal line on a Distance time graph means the object isn't moving. But a horizontal line on a velocity time graph means that the object is going at a constant/steady speed.

[myGCSEscience]

Yup, exactly that.

At 1:10, the YouTube transcript says that you say something completely different! XD

[myGCSEscience]

I wouldn't use the transcript, most of the time it is way, way of!

god bless. You are truely awesome

[LukeRodgersIsGOD]

Much appreciated, huge fan.

For the last one, do you get the marks if you were intended to use this formula : 0.5(a+b)h ... (area of trapezium)

hahaha 1:10

Watching this with captions is hilarious.

there's a special place in heaven for people like this

[sarg sen]

Area is m squared :D

[mackiwawa]

I got 650m to last question

[Sherlock H]

I should hope so! :P. "bus like dick sweat sup what we do speak"

When using a velocity-time graph that shows a deceleration of a moving object, because the formula says "Final Velocity - Initial Velocity / Time" would that mean that the acceleration of the moving object would be a negative number because the final velocity is 0 seconds and the initial velocity is, for example, 12 m/s (0/12 = -12)

will the exam ever ask you to calculate the distance traveled in total?
