AQA AS PHYSIC PAPER 2 MARKING SCHEME JUNE 2023 'a non contact form acts on each magnet' - ANSmagnets aren't touching but both experience a force 1GHZ = - ANS1x10^9 HZ describe how to plot the magnetic field pattern of a bar magnet - ANSplace a compass near the north pole of the magnet and mark the direction that the compass points move the compass around the bar magnet to the other pole, marking at intervals the direction the compass points join the points up and add an arrow pointing from the north poe to the south pole difference between vector and scalar quantity - ANSa vector has a direction but a scalar does not effect of time of contact with ball and distance ball travels - ANSlonger time of contact the greater the change of momentum since the mass of the golf ball is constant, the velocity of the golf ball must increase, which increases the distance the ball travels example of vector quantity - ANSvelocity force weight acceleration displacement explain the effect on the motion of a ball bearing when the switch is closed - ANSclosing the switch causes a current in the coil a magnetic field is created a force of attraction acts on the ball bearing so the ball bearing accelerates towards the iron nail force = - ANSmass x acceleration
