Gravity

Well, darling, the force with which gravity pulls on objects close to Earth is approximately 9.81 meters per second squared. It's what keeps us grounded and stops us from floating off into space like a lost balloon. So, if you ever feel like you're being pulled down, just blame it on good ol' gravity.

A balloon filled with helium or hot air is less dense than the surrounding air, causing it to float. The buoyant force acting on the balloon is greater than the force of gravity pulling it down, allowing it to defy gravity and float upwards. This principle is known as buoyancy, based on Archimedes' principle, which states that an object will float if it is less dense than the fluid it displaces.

Gravity plays a crucial role in the operation of roller coasters by providing the necessary force to propel the cars along the track. When a coaster climbs to a high point, gravitational potential energy is stored, which converts to kinetic energy as the train descends. This energy exchange allows the coaster to gain speed and navigate loops and turns. Ultimately, gravity ensures that the ride is thrilling while keeping it safe within the design of the track.

'Gravoty' is an attraction between any two or more objects, be those objects atoms, protons or planets. stars andything in between.

The planets have gravity , the Sun has gravity. They are attracted to each other. So why do they not 'crash' into each other? Because, the planets are moving with an acceleration. This acceleration together with the planets mass creates are force (F = ma). This force is balanced by the Sun's force of gravity. So the forces are in balance, so the planets orbit the Sun and not fall into the Sun.

The oceans on Earth, being liquid, will be attracted to the Moon by Lunar gravity. So which side of the Earth the Moon is on , will be the 'High Tide'. This is balabnced 'Like a wheel balance', by a counter High Tide on the opposite side of the Earth, from the Moon.

If we didn't have gravity, all objects on Earth would float off into space in a straight line at a constant velocity. Without gravity, there would be no force keeping celestial bodies in orbit around each other, leading to chaos in the solar system. Additionally, the absence of gravity would have profound effects on the human body, as our bones and muscles rely on gravity to maintain strength and structure.

Friend Hilmar Zonneveld is perfectly and absolutely right. Weight, being a vector, of an object will always act through the center of gravity. Also definition of centre of gravity confirms that whatever be the position the weight would always act through a point known to be center of gravity

It isn't, necessarily. But the force of gravity is constant, whereas the force

of air resistance depends on how fast you're moving through the air. So when

you begin to fall, gravity is stronger, and it makes you fall faster and faster.

But as your speed increases, so does the force of air resistance, and eventually,

the force of air resistance builds up to be equal to the force of gravity. At that

point, you keeep falling, but your speed doesn't grow any more.

Oh, what a fantastic question! Now, you see, every object in our world, big or small, has a tiny amount of gravity. It's like a soft hug that everything shares, bringing a sense of connection to everything in our beautiful universe. Keep exploring curiosities like this, my friend – you're on a wonderful journey of discovery.

Yes, asteroids have gravity, but it is much weaker than the gravity on Earth. This is because asteroids are much smaller and less massive than Earth, so their gravitational pull is significantly lower.

Well, friend, gravity is what pulls objects downward towards the Earth's center. It's like a gentle hug from Mother Nature keeping us feeling grounded and connected to this beautiful planet. Just remember to walk lightly and breathe deeply as you go about your day on this wondrous Earth.

Gravity is a force that pulls objects towards the center of the Earth. It influences the push or pull of objects by determining how much they weigh and how they move. Objects with more mass experience a stronger pull of gravity, while objects with less mass experience a weaker pull. This force of gravity affects how objects move and interact with each other on Earth.

Gravity is a force that pulls objects towards the center of the Earth. It is what keeps us grounded and causes objects to fall when dropped. Gravity also affects the motion of planets, moons, and other celestial bodies in our solar system. It is responsible for keeping the Earth in orbit around the Sun and the Moon in orbit around the Earth.

Gravity is a fundamental force that is created by the presence of mass in an object. It causes objects with mass to be attracted to each other. In the universe, gravity plays a key role in shaping the structure of galaxies, stars, and planets, as well as influencing the motion of celestial bodies. It keeps planets in orbit around stars, holds galaxies together, and determines the trajectory of objects in space.

Light is affected by gravity in the universe through a phenomenon called gravitational lensing. This occurs when the gravitational pull of massive objects, like galaxies or black holes, bends the path of light as it travels through space. This bending can distort or magnify the appearance of distant objects, providing valuable insights into the distribution of mass in the universe.

Well, friend, you see, gravity is what keeps us rooted to the ground and creates a beautiful balance in our world. While gravity exists everywhere in our universe, there are special situations, like in outer space, where its effects can feel different. So, just remember, no matter where you are, gravity is always there painting a masterpiece of harmony around us.

Oh, what a good question! Gravity is like a gentle hug from Mother Nature that works its magic on everything around us. It is actually pretty quick at its job, acting instantly on objects to pull them towards each other with a lovely sense of connection. Just like how painting one happy little tree can instantly bring joy to a whole landscape. Amazing, isn't it?

Gravity is a force that exists between all objects with mass. It is caused by the curvature of spacetime around massive objects, such as planets and stars. This curvature causes objects to be attracted towards each other, with the strength of the gravitational force depending on the mass of the objects and the distance between them. In simple terms, gravity works by pulling objects towards each other, keeping planets in orbit around stars and objects on Earth's surface.

Gravity on Earth is caused by the mass of the planet pulling objects towards its center. This force affects all objects on Earth by keeping them grounded and causing them to fall towards the ground when dropped. Gravity also influences the motion of celestial bodies, tides, and the shape of the Earth itself.

Well, hello there! Gravity is caused by mass. When objects have mass, they exude a gravitational pull that attracts other objects towards them. It's like a gentle hug from the universe, keeping everything moving and connected in a beautiful dance.

Gravity is a fundamental force in the universe that was created by the presence of mass. It influences the universe by causing objects with mass to be attracted to each other, keeping planets in orbit around stars and galaxies together.
