Gravity

One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

Under what circumstances would your weight become zero?

The weight will become zero under the following circumstances:

  1. In an artificial satellite
  2. During free fall
  3. At the centre of the earth
  4. At a point where gravitational pull of earth is equal to the gravitational pull of the moon.

Is it possible for the gravitational force between two 50kg objects to be les than the gravitational force between a 50kg object and 5 kg object?

Gravitational force is a result of distance and mass. If the 50 kg and 5 kg objects were extremely close to each other and the 2 50 kg objects were really far apart from each other, then the gravitational attraction between the 50 kg and 5 kg object could be greater. However, if they are the same distances apart, the attraction with the most combined mass will have the strongest gravitational force.

What is the law of gravity in child's understandig?

The law of gravity is a force that pulls things towards the Earth. It is what keeps us from floating off into space. Things fall to the ground because of gravity, and it is what makes objects feel heavy.

How many types of gravity are there?

There is only one type of gravity, which is the fundamental force that attracts objects with mass towards each other. It is described by the theory of general relativity proposed by Albert Einstein.

What is gravity definition?

Gravity is the force of attraction between objects that is due to their masses.

How strong is gravity on Comet 67P?

Gravity on Comet 67P is much weaker than on Earth, as it has a mass that is only a fraction of Earth's. The surface gravity on Comet 67P is estimated to be about 1/100,000th of Earth's gravity, making it very low and allowing for objects to be easily lifted and moved around.

What types of shapes and forms seem to defy gravity?

Some examples of shapes and forms that seem to defy gravity include structures like cantilevered buildings or bridges, objects balanced on a single point, and artworks that give the illusion of floating or defying typical orientation. These designs challenge our perception of balance and stability, creating visual interest and a sense of awe.

How does gravity affect objects with different masses?

Gravity affects objects with different masses equally, causing them to be pulled toward the center of the Earth at the same rate. However, objects with greater mass will have a greater force of gravity acting on them, making it more difficult to move them or change their trajectory.

How do you increase and decrease gravity?

To increase gravity, you would need to increase the mass of the object or planet exerting the gravitational force. To decrease gravity, you would need to reduce the mass of the object or planet exerting the gravitational force. Another way to decrease gravity is by increasing the distance between the objects experiencing the gravitational force.

Gravity is greater than what?

In the context of celestial bodies, gravity is greater on larger objects with more mass. For example, Earth's gravity is greater than the moon's gravity due to Earth's larger size and mass.

What property of matter does gravity depend on?

Gravity depends on the mass of matter. The larger the mass, the greater the gravitational force it exerts.

Is gravity and buoyancy the same size?

No, gravity and buoyancy are not the same thing. Gravity is the force of attraction between objects with mass, while buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. Buoyancy depends on the density of the fluid and the volume of the object, while gravity depends on the mass of the objects involved.

Sentence describing gravity and weight?

Weight is a force equal to the product of an object's mass and gravity. Gravity in this context is not a force but an acceleration. Near the Earth's surface, that acceleration is 9.8 m/s², regardless of the mass.

Is gravity a force mass distance?

Gravity is a force that exists between any two objects with mass, and it acts over a distance. It is proportional to the masses of the objects and inversely proportional to the square of the distance between them, as described by Newton's law of gravitation.

What did newton do to confirm his hypothesis about gravity?

Newton confirmed his hypothesis about gravity by developing the Universal Law of Gravitation, which described the force of gravity between two objects. He used this law to predict the motion of the planets and the Moon, which matched observations made by astronomers, confirming the validity of his theory.

How does bouncing on a trampoline effect gravity?

Bouncing on a trampoline does not affect gravity itself. Gravity still exists and exerts the same force on you whether you are on a trampoline or not. However, the trampoline provides a surface that can help you overcome gravity's pull temporarily, allowing you to experience the sensation of jumping higher than you could on solid ground.

Does a mug full of water appear lighter inside the water?

No, the water inside the mug won't appear lighter. The perceived weight of the mug may seem less due to the buoyant force acting on it in water, but the water itself won't change its color or weight when viewed inside the mug.

What is the force that govern the motion in the universe?

Gravity is the dominant force that governs motion in the universe on a large scale, such as the motion of planets, stars, and galaxies. It is responsible for keeping celestial bodies in their orbits. On a smaller scale, other forces like electromagnetism and nuclear forces also play a role in governing motion.

Does gas has a flat surface because of gravity?

Gas does not have a flat surface due to gravity. Gas molecules are constantly moving in all directions, leading to a more random and spread-out distribution. Gravity does play a role in keeping gas molecules bound to Earth, but it does not affect the shape of the gas itself.

What is the force of gravity on mars in newtons per kg?

Look up the gravitational acceleration, in meters/second square, for example in the Wikipedia article about "Mars". Meters/second squared is the same as newtons/kilogram.

What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 m s?

The only factor needed to calculate change in velocity due to acceleration of gravity is time. The formula to calculate the change in velocity is: change in velocity = acceleration due to gravity * time.

Why don't you move when you push on a sturdy wall?

Because of Newton's 3rd law, if you push on a wall with, let's say, 10 N, the wall will, by definition of the law, push back on you with 10N. The forces are balanced and you don't move backwards because the forces "cancel out" because they are equal and opposite, and if Fnet=0, we now acceleration must be 0.
