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

Dancers do not often understand the physics and mathematics describing their movements‚ but they know how to execute them with grace. If ballerinas were not able to feel physics‚ they would fall over. Legs‚ arms and head are oscillating as they turn– moving back and forth in seemingly separate patterns. For dancers‚ everything must move in separate patterns‚ yet at the same time‚ move at the same rhythm. This presentation introduces the history‚ mathematics‚ and physics behind ballet. Ballet originated

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)

Holiday’s homework Class IX 1. Is potential energy a vector or a scalar quantity? 2. A train travels at a speed of 60 km/hr for 0.52hr‚ at 30 km/h for the next 0.24hr and then at 70 km/h for the next 0.71h.What is the average speed of the train? 3. Plot the distance – time graphs a) When the body is at rest b) When the body is moving with a uniform speed c) When the body is moving with a non-uniform speed. 4.
