Hi Folks, I am a private tutor and one thing I teach is A level Physics (OCR Physics A).
Am I the only person who has been sometimes baffled and deeply disappointed with some of the questions/answers? Let me explain what I mean.
I see questions form which it's not possible to decide what kind...
Homework Statement
[/B]
The problem is with part b(ii). This is an A level question so only elementary concepts are to be used.
Homework Equations
$$E = \frac{1}{2}kx^2 $$
The Attempt at a Solution
EPE should be max at 0, 0.4, 0.8 since E is a function of $x^2$. However, mark scheme only...
Homework Statement
I have derived the expression for the velocity of the satellite v= root of GM/r however I'm struggling to derive an expression for the centripetal acceleration of a satellite orbiting Earth.
Homework Equations
The Attempt at a Solution
I'm not entirely sure which equations...

Over 40 years ago, the Apollo astronauts placed reflectors on the surface of the Moon. These are still used by a number of observatories on Earth to monitor the distance to the Moon by reflecting pulses of laser light from them and detecting the reflected signal...
Background question:
A bicycle and rider have a combined mass of 75 kg. They freewheel down a slope whose maximum height is 6 meters above sea level. The slope is 20 meters long. At the end of the slope, the bicycle and rider are travelling with a velocity of 10 m/s. Calculate the work done...
Homework Statement
An aircraft flies with its wings tilted, in order to fly in a horizontal circle of radius r. The aircraft has mass 4.00 x 104 Kg and has a constant speed of 250ms-1 . with the aircraft flying in this way, two forces are acting on the plane, P [lift] and W [weight which is...
I can't seem to post pictures, but I will give the link to the question along with the link to the answer given in the mark scheme. Here goes:

I would like to make contact with others who perform A level physics tutoring in the UK, especially those who are online providers
I have tutored AS/A2 students over a period of time and would like to share ideas and information with others doing the same
