Degree: Chemical Physics (Masters) - Bristol University
Hi I'm Tim and I am a third year Chemical Physics student at the University of Bristol which means I do half chemistry and half physics. This means I am passionate about and extremely comfortable tutoring maths, physics and chemistry.
Why can I help you?
I finished my A levels fairly recently and as such I know the stresses which come with studying multiple subjects. At A level, I achieved A*s in maths, further maths and additional further maths as well as an A* in chemistry and an A in physics.
I tutored students in younger years in maths and physics whilst at school and I tutored a friend maths A level, heping him move his grade from a D to a B.
There is no such thing as a stupid question and I'm ready to help you achieve the best you possibly can.
Don't hesitate to get in touch, I'd love to hear from you!

Whilst at first this question looks difficult, once broken down it becomes quite easy. It is a simple case of energy exchange.
The pole vaulter gives themselve kinetic energy as they aproach the bar, and turn this into gravitational potential energy in order to get the height. This means we can equate the two terms for kinetic and potential energy:
1/2 m v^2 = mgh
And rearrange to give:
h = 1/2 * v^2 / g
Assuming an athlete can run at 10 m/s and take g as 10 m/s/s, the height comes out as 5m.
The question can then be extended by saying that the pole vault world record is 6.16m, so where does the extra metre come from?
An assumption has been made that the athlete is a particle acting from the centre of mass of the athlete which will be about a metre off the ground.see more
