Summary - Motion: Whenever a body changes its position continuously with respect to the position of other bodies around it then it is said to be in motion Rest: An object which does not change its position with respect to its surroundings is said to be at rest Distance: It is the actual length of t..

Mass is defined as the amount of matter contained in it. SI unit of mass is Kilogram. Mass remains constant throughout the universe. Mass of an object can never be equal to zero. Mass is a scalar quantity. Weight is the force with which an object is pulled towards the cen..

Summary - Electric potential is the condition that determines direction of flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit positive charge from infinity to that point. Electrical potential is a scalar quantity. ..

. The arrows give the direction of the conventional current. Current is a scalar quantity. The direction of conventional current in any circuit is the direction in which the positive charges flow. Mathematically, for a steady current across any area, where I is the current, and q is the c..

Distance and Displacement - Suppose a bus starting from a terminus A travels 15000 m to reach terminus B. Then the distance covered by the bus is 15000 m. Now if the bus returns to the terminus A, then what is the distance covered by the bus during the return trip? The distance covered is 15000 m. ..

electron causing them to move as shown in the figure. The arrows give the direction of the conventional current. Current is a scalar quantity. The direction of conventional current in any circuit is the direction in which the positive charges flow. Mathematically, for a steady curren..

Step 1: Potential is a scalar, hence no direction is involved. Step 2: The point where the potential is to be found is x = 0. Step 3: Which are the charges and where? All the charges are equal to 'q'. Position at 1m, x = 2m, x = 4m, x = 8m, Step 4: The sign of all the charges is positiv..

Ampere's Circuital Law - Ampere's law is a useful relation that is analogous to Gauss's law. Ampere's law is a relationship between the tangential component of magnetic field at points on a closed curve and the net current through the area bounded by the curve. Ampere's law is formulated in terms o..
