Perfect Answers (according to the SQA)

I will add and adapt these as I go through the past papers. If you’ve got additional definitions do pass them on. These would be great written on cue or flash cards. Go through past papers and record any common phrases or answers.

Proving the equations of motion

If you don’t like proving v2=u2+2as from v=u+at then use this neat little sheet from Mr Mackenzie.

Below are the 16 graphs to try to learn. Going across a row from L to R shows graphs drawn from the gradient of the previous graph. Therefore if you write the axes on for s-t, v-t and a-t you can work backwards and forwards to quickly picture the shape of the graph you require.16graphs

Friction always acts to oppose motion. If the object is sliding down the slope then friction must act up the slope, but if the object is being pushed up the slope then friction acts down the slope.friction down slopefriction up slopeThe component pushing into the slope (mg cosθ) is balanced by the reaction force from the slope.

Collisions Seatbelts, crumple zones, airbags, helmets etc are all designed to reduce the force on a person, by increasing the time of contact. In all cases the change in momentum or impulse remains the same as the vehicle/ object still has to come to rest from its initial speed.lower force

Show that the frequency f of the sound heard by the passenger is given by where symbols have their usual meaning.Doppler proof

Although we talk about the Big Bang, it is important to emphasise that the universe, ie space, is expanding. There are a number of characteristics that indicate it is an expansion and not the result of an explosion.

Explosion Expansion
Different bits fly off at different speeds Expansion explains the large-scale symmetry we see in the distribution of galaxies
Fast parts overtake slow parts Expanding space explains the redshifts and the Hubble law
Difficult to imagine a suitable mechanism to produce the range of velocities from 100 kms–1 to almost the speed of light Expansion also explains redshifts and the Hubble law even if we are not at the centre of the universe

 

Type of Collision Momentum Kinetic Energy Total Energy
Elastic Conserved Conserved Conserved
Inelastic Conserved Reduced Conserved
Explosions Conserved

zero at start and finish

here Ep is converted to Ek so Ek increases Conserved

Hope these are helpful. Let me know if you want me to add anything further.
