idk but i think the first MC answer is C, not B, but i could be wrong.
I agree, the level of maths in the paper made for a better paper in my opinion. Just glad nothing came up on x-ray crystals or anything like that. Overall not a bad test. some hard parts but mostly straight forward.It was more mathematical and more Physics related (ie. no lame "assess" questions) than other years. I liked it
That's what I thoughtnumber 1 is c. if u forgot the speed changes caus of the slingshot affect, the gravity and rotational motion of the earth propels the object changing its speed, or decreasing its speed.
exept for the Analyse question. but i liked it too.It was more mathematical and more Physics related (ie. no lame "assess" questions) than other years. I liked it
Ohhh I agree with you no question about it but what are we looking for here the BEST answer right????clonestar, d is like the basic definition for GPE but however u r asked 4 the difference not just a point. u don't need the work of moving infinte 2 tat higher orbit. ur basically only need 2 apply the difference between the 2 lvls and through law of conservation of energy it would archive the specific GPE and altitude of the higer orbit. (i've done alot of mathmatical question on it eg. find the extra kinetic energy required 2 move a satellite by blah blah altitudes which is finding the workdone (workdone=energy))
nice question, it was a nicely snuck in projectile Q
