A2 6PH04 Physics Unit 4 'Physics on the Move' - 11th June 2012So.... fair to say January was a flop for me!
After somehow managing to lose at least every other mark, I'm now revising hard for this paper! (And five others....
)
Anyway, in my revision I managed to compile a lot of papers etc, and was going to post them here, but I have decided to put them all together on a site for ease of access.
I've put everything that I have here on my comp so far, will scan and upload all of my revision posters from January too.
Also I really don't know who I got all of the stuff from, but if it was from you, please just let me know and I'll put a link back to your TSR profile.

Iif you have ANYTHING, like extra practice questions and answers or something, please post them here or message me, and I can add them to the site.Last edited by whooshpaddy; 15-03-2012 at 19:27. -

Re: A2 6PH04 Physics Unit 4 'Physics on the Move' - 11th June 2012Revision Checklist here for the Further Mechanics Section:
Section One – Further Mechanics
Momentum and Force
• Use the equation p=mv• Relate net force to rate of change of momentum in situations where the masses of the objects do not change (this is Newton's second law of Motion)
Momentum and Collisions
• Apply the principle of conservation of linear momentum to problems involving objects moving along in a straight line• Derive and use the expression Ek=p^2/2m for the kinetic energy of particles (for particles moving much more slowly than the speed of light)• Use data to calculate the momentum of particles• Apply the principle of the conservation of linear momentum to problems in one and two dimensions
o (so you need to be able to resolve forces, and speeds, using trigonometry)• Explain the principle of the conservation of energyo Energy cannot be created or destroyed. Energy can be transferred from one form to another but the total amount of energy in a closed system will not change.
• Use the principle of the conservation of energy to determine whether a collision is elastic or inelastico Work out the total kinetic energy before (Ek1) and after (Ek2) the collision. If Ek1=Ek2, the collision is elastic, as kinetic energy is conserved in elastic collisions. If Ek1>Ek2,the collision is not elastic, as energy has been transferred to forms other than kinetic.
Circular Motion 1
• Express angular displacement in radians and in degrees , and convert between those units• Explain the concept of angular velocity• Use the relationships ν=ωr and Τ=2π/ω• Derive and use the expressions for centripetal acceleration a= ν2/r and a=rω2
Circular Motion 2
• Explain that a resultant force (centripetal force) is required to produce and maintain circular motion.• Use the expression for centripetal force F=ma =mν2/r -

Re: A2 6PH04 Physics Unit 4 'Physics on the Move' - 11th June 2012The average for this paper is consistently about 5% below the average for unit 5.(Original post by Callitoff)
Nice one! Without a doubt this is the most daunting exam for me this summer :/
It is easily the hardest A2 paper of them all!

Re: A2 6PH04 Physics Unit 4 'Physics on the Move' - 11th June 2012Yeah it was really hard, there weren't many calculations and most questions seemed really long compared to the amount of marks they were worth :/(Original post by SKK94)
Did anyone solve the January 2012 paper??
Unit 4 seemed quite manageable until I tried it out..

Re: A2 6PH04 Physics Unit 4 'Physics on the Move' - 11th June 2012What happens then? (I am not asking the fusion process but the expirements at CERN)(Original post by Josh.Holloway)
as there is electrostatic repulsion between the two positively charged particles, high energies are needed to overcome that for strong nuclear force to take over.
What is the purpose of colliding them and overcoming strong nuclear force(s)?Last edited by Yorrap; 27-04-2012 at 03:23. -

Re: A2 6PH04 Physics Unit 4 'Physics on the Move' - 11th June 2012That's right.(Original post by Josh.Holloway)
to reveal/study the internal substructure and mass of the particles, i think.
