The Electric Field inside a Conductor The nuclei of the atoms of a conducting solid remain almost in their places in the crystal lattice‚ while the electrons relatively move a lot. In an insulator‚ the electrons are constrained to stay with their atoms (or molecules)‚ and at most‚ the charge distribution is displaced slightly. The motion of the electrons due to the external electric field constitutes an electric current. Since the negatively charged electrons are moving to the left‚ the current

Year 11 Preliminary Assignment #2 – Physics Electricity in the Home Aim: Will the current (Amps) affect the time it takes for a slot car to complete a lap of the track? Planning the investigation: 1. What do you know about the topic from personal experience? From playing with slot cars and building tracks even before I embarked on the physics course‚ I’d always realised the relationship between the trigger and the speed of the cars. In the investigation‚ I hope to use a more scientific method

2: SPEED‚ VELOCITY AND ACCELERATION 2.1 Distance and Displacement • Distance is the total length covered by a moving object irrespective of the direction of motion‚ i.e. only the magnitude is of importance. • Displacement is the distance measured in straight line AND in a specific d__________________. Both magnitude and d_________________ are important. Example 1 A car travels 5 km due east and makes a U-turn back to travel a further distance of 3 km. Find (a) the distance covered‚ (b)
