Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. Sir Isaac Newton (1642 -- 1727) discovered that a force is required to change the speed or ...
3. Activity: Explain that the sheet represents spacetime, the large object represents the Sun and the smaller object represents a planet. Have the students pull the edges of the sheet outward. Make sure the sheet is taut. Roll the lighter balls across the sheet. Note how they travel in a straight line. Place the heavy object in the center of ...
Mar 31, 2022 · Answer: It is the measure of weight of the body. Gravity is a vector quantity. It is always directed towards the centre of earth. Variation of acceleration due. (i) Effect of Height : As we go above the surface of the earth, acceleration due to gravity (8) goes on decreasing vrien. Explanation: hope this is your answer.
Sep 16, 2020 · Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides
Apr 4, 2020 · Explanation: →→A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. ... Some scientists think there could be as many as one hundred billion galaxies in the universe.
Dec 21, 2023 · Gravity is the force that attracts two objects together. It's also known as gravitatio. Gravity affects objects of all sizes, from subatomic particles to clusters of galaxies. Objects with mass have a gravitational pull, and the more massive the object, the stronger the pull. Gravity is what keeps us on the ground and causes objects to fall.
Mar 8, 2021 · Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
Dec 23, 2020 · Define center of gravity and its application in sports . Explanation: Lowering the centre of gravity increases balance and stability in sport. This is why you can change direction faster by bending your legs and getting lower to the ground. It increases your stability, allowing you to adjust to greater force production by the legs.

May 9, 2024 · The strength of this pull depends on the masses of objects at play. Gravity keeps the planets in orbit around the sun and the moon around the Earth. Hence, we define gravity as: Gravity is a force that attracts a body towards the centre of the earth or any other physical body having mass. Gravity has the same effect on all objects.
