Physics Questions

Elasticity is measured as ratio of stress to strain. For a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber.

Therefore, with the help of Young's modulus, it can be concluded that steel has greater elasticity than rubber.

Energy can be either potential or kinetic. The energy associated with motion is called Kinetic energy and similarly, the energy associated with position is called Potential energy.

An electric motor is an electrical machine that converts electrical energy into mechanical energy.

Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. 

A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by dispersion of sunlight by tiny water droplets, present in the atmosphere. A rainbow is always formed in a direction opposite to that of the Sun. The water droplets act like small prisms. They refract and disperse the incident sunlight, then reflect it internally, and finally refract it again when it comes out of the raindrops.

The watt(symbol: W) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. In dimensional analysis it is described by

We know that Kinetic energy is the energy of a moving object and in the same way Electrical energy is the form of kinetic energy caused by moving electric charges called electrons.
