Here I look at the forces acting on a lift and a particle inside the lift as it moves at constant speed, accelerates and decelerates.

If you’re in a rush this video is perfectly comprehendible at 1.5x speed :)

2x speed is fine too!

Tf u on about? I watch literally everything on 2x speed

I had no clue what the equations my teacher was writing in lessons but now you have cleared so much up for me with you deep and very applicable style of teaching. Thank you for these videos, you should feel proud for educating students so well.

5:26 If acceleration is a vector, then if "a" is negative, T_1 would not always be greater than T? Since it would be (M+m)g - (M+m)a Which bit am I missing

Is R2 the force exerted by the person?

@ExamSolutions_Maths 4 жыл бұрын

No that is the reaction from the floor exerted on the person. The force exerted by the person is their weight, mg N

At 6:40, surely if the reaction force is bigger, surely you'd feel yourself being pushed upwards, not driven down into your seat, because the reaction force is an upward force?

@JamieD1233 4 жыл бұрын

The seat is being driven upwards in comparison so you so as it pushes you up inertia makes you feel pushed down

Is deceleration as same as downward acceleration.

@ExamSolutions_Maths 8 жыл бұрын

+Ahmed Hassan No. Deceleration is when something is slowing down. Deceleration is the same as negative acceleration.
