1. At first, Force A is bigger than Force B 2. So the object accelerates. 3. Eventually (whilst Force A remains constant) Force B increases. 4. When Force A = Force B, the object reaches terminal velocity (constant speed).
June 16, 2024* Unlike magnetic poles attract and like magnetic poles repel. * Permanent magnets: produce their own magnetic field. * Induced magnets: become magnetic when placed in a a magnetic field. * Magnetic field lines are always drawn from North to South. * Stronger magnetic field: draw more lines closer together. * Plotting compasses can show the
June 13, 2024* Generator effect: a voltage is induced in a conductor/ coil when it moves through a magnetic field or when a magnetic field changes through it. * Generator effect in lab: move the conductor in a fixed magnetic field or move a magnetic field relative to a fixed conductor. * Generator effect in
