What is the importance of the universal law of Gravitation?

Content Curator

According to the Universal Law of Gravitation, every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them.

The importance of the Universal Law of Gravitation is as follows:

It explains the phenomenon of revolutions of heavenly bodies: All heavenly bodies or celestial bodies like planets and satellites move in an elliptical orbit due to gravitational force.
It tells us about the force that is responsible for binding us to the earth: The gravitational force of attraction between the earth and us helps to keep us on the ground. Since the mass of the earth is very large compared to us, so we are attracted to the earth.
It explains the formation of tidal waves: Ocean tides result from the rise and fall of water levels due to the gravitational force exerted by both the sun and moon.
A planet's orbit around the sun, a moon's orbit around the Earth, and an artificial satellite's orbit around the Earth are all explained by the law of gravitation.
Rainfall, snowfall, and the flow of water in rivers on the planet are also explained by the universal law of gravitation.

A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.

In an experiment with convex lens of focal length f, the screen is fixed at a distance D from the object. A student slowly moves the lens away from the object towards the screen and finds that she is able to form sharp image of the object for two positions of the lens. The distance between these two positions of the lens is d.

Capacitors are manufactured with certain standard capacitances and working voltages. However, these standard values may not be the ones that are actually needed in a particular application. Two or more capacitors can be grouped in series or in parallel to achieve desired capacitance and voltage. When connected in series, the total capacitance decreases while the voltage rating increases, whereas in parallel connections, the total capacitance increases and maintains the same voltage rating. A capacitor stores energy in the electric field between its plates and stored energy is proportional to the square of the voltage and capacitance $U = \frac{1}{2}CV^2$, where symbols have their usual meanings.
Two capacitors, one of $3 \ \mu$F and the other of $6 \ \mu$F, are connected in series in the circuit as shown in the figure, for a long time. }
