Venn diagrams are simple visual representations of sets using circles or closed curves. Venn Diagrams help in understanding and solving problems involving union, intersection, and difference of sets. Venn diagrams make it easier to visualize relationships between sets and are especially useful in word problems and data classification.
When two circles/ closed curves overlap, the common area is called intersection. Whole area including the intersection is known as union of sets. if the two circle don't overlap, its called disjoint sets.

When there is no normal force acting on a body, weightlessness is experienced, and the body free fall under gravity. The concept of gravity is still acting on the body, however, there is no weight sensation of any reaction force from any surface or ground. The weightlessness felt by the astronauts in an orbiting spacecraft is not because gravity is not present but because while they are moving forward, both, they and the spacecraft are in continuous free fall towards the Earth. The role of the normal force in defining weight can be understood from this phenomenon also how it is different from the actual gravitational force.

The gravitational pull of the Moon is the main reason behind the tides of Earth and it is less dependent on the sun. The gravitational pull of the moon on Earth is stronger than the sun's gravitational pull due to Earth's proximity to the moon. The Earth's oceans get pulled by the moon's gravity, which creates a bulge of water on the side of the Earth facing the moon. Also, another bulge gets created on the opposite side due to the water's inertia. When the earth rotates, its areas pass through these bulges which form the high and low tides. Each day, two high and two low tides are created by the gravitational interaction.
