The weight of a body is the force with which it is attracted in the direction of the centre of earth. When an object is stationary with respect to the planet, its weight equivalent to the gravity. This weight of the object is known as its static or true weight.
We become conscious of our weight, in that case when our weight is opposed by some other object. Generally, the operation of measuring the weight of a body with a weighing machine lies in the fact that as we place the body on the machine, the weighing machine repulses the weight of the object. The reaction of the weighing machine to the body gives the calculate of the weight of the body.

Erika is on an elevator and presses the button to go down. When the elevator first begins moving, it has an acceleration of 2.5 m/s 2 downward. Erika and the elevator have
Polarization: The dipole moment per unit volume of the solid is the sum of all the individual dipole moments within that volume and is called as 'Polarization' P of the solid.
A 7.25-g bullet is fired from a gun. The muzzle velocity of the bullet is 223 m/s. Suppose that the bullet accelerates at a constant rate along the barrel of the gun before it
INSTANTANEOUS ACCELERATION: The acceleration of the body at any certain instant during its motion is called to be an instantaneous acceleration.
Illustrate the polarity of Barrier potential. The free electrons which cross over the junction recombine with the holes of p-type and uncover some of the negative ac
