Gravitational Acceleration is 9.8 m/s^(2). This is a mean figure for Earth. At different points on the Earth's surface the above figure will vary very slightly.
However, different objects in space have different gravitational accelerations.
The Moon is 1.625 m/s^(2)
The Sun is 274 m/s^(2)
Since Earth and Venus are roughly the same size AND have roughly the same mass, they have roughly the same gravity. The acceleration of gravity on the surface of Venus is 90.3% of what it is on Earth's surface.
No. Gravity on Mars is about 38% of what it is on Earth.
The gravitational acceleration on Earth is approximately 9.81 m/s^2.
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
Well sometimes it is and sometimes it isn't. That old saying is not nessary true. Because there are plenty of planets in the universe that are the same size as earth but have less gravity than earth.
Since Earth and Venus are roughly the same size AND have roughly the same mass, they have roughly the same gravity. The acceleration of gravity on the surface of Venus is 90.3% of what it is on Earth's surface.
The gravity of the sun is more. The sun is the roughly the size of 946 Earths.
Venus is a planet that is closest in size to Earth. It has similar bulk composition and gravity to Earth too.
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
No. The gravity on Venus is about 90% of what it is on Earth.
No. Gravity on Mars is about 38% of what it is on Earth.
The gravitational acceleration on Earth is approximately 9.81 m/s^2.
Mars is smaller than the Earth, with about 38% of Earth's gravity and days which last about 24hrs 40mins.
Mars has approximately one third the surface gravity of the earth
No. At the centre of the earth the acceleration due to gravity is ZERO
Because the shape and size of the object dont change, only the gravity affecting it
