thank you ☺️

[@daniaalali361]

Can I describe the object's movement by saying : speeding up , slowing down , constant speed ? or are there other scientific descriptions we should use ?

[@muhammadazeem7538]

In position time graphs, you can describe motion only in terms of positive or negative direction. Velocity is always constant

[@saifalnaqbi8200]

lets say that the graph is downwords can we still say that the slope is rise/run ?

[@muhammadazeem7538]

Yes, because this is the definition of a slope

[@Selwan_a]

when the line under zero the velocity will be zero or negative?

[@muhammadazeem7538]

Velocity will be negative

[@mariamalshehhi1505]

Doctor is this Use to determine the overall displacement (in m) of the object during the seconds of motion?

[@muhammadazeem7538]

Yes, we can do that also

[@Selwan_a]

doctor i recommend to use a phone stand it will be easier for you and we can focus more

[@hamdanalhosani6573]

A and B are negative but C and D are positive

[@muhammadazeem7538]

This is not a complete description

[@mahraalhammdi9236]

Doctor the velocity can be negative?

[@muhammadazeem7538]

Yes, i will discuss it further in live lecture

[@ahmedalsuwaidi4786]

Hi doctor, will you do online lecturers on blackboard and thanx for the vid.

[@muhammadazeem7538]

No, all lectures will be like these for next 3 weeks

[@saryamuazzen6316]

Doctor when I calculate the slope take one point or two point ??

[@muhammadazeem7538]

Good question. Actually you can calculate slope at a single point also but that i will explain in my next video. In this example, you will choose two points, any two points on the time axis. Thanks

[@mahdialattar6132]

much*

[@امنه_1-ز8ج]

Hi sir... the time it will be always in horizontal line? Or I can put it in any line? Amna Mohamed

[@muhammadazeem7538]

Time is an independent variable therefore it is always along the horizontal axis. It is conventional. You will not see time along the vertical axis evver.
