hey guys, when you work out the (GPE) if the mass is 10.1 and height is 13m. Will this calculation be right 10.1 * 13 = 131.3j or 10.0 * 10 * 13 = 1300j,

help please
GPE = Mass (kg) x gravitational field strendth (which is always 10 unless they say otherwise x height
So it would be 10.1 (kg?) x 13 x 10 = 1313 J
You said 10.1 for the mass but wrote 10.0 for the calculation so it would be 1313 or 1300 depending on what it is
Guys i think the best thing to do now is go over all the formulas because paper1 consists of questions asking us formulas and then to apply them.Do light,energy,waves and electricity chapters properly and all experiment precautions because they are worth 1 2 marks which no one wants to lose here and the grade boundaries have always been low like 111 for an A so just go over all the experiments and their precautions and yeah dont be tensed it will be an easy paper like chem though bio gave us a tough time but tats gone now Best of luch their still 2 days left and you can do the course And do go over these notes http://www.shawonnotes.com/index/igcse_physics/0-6
