Planet X has an acceleration due to the gravity of 20 meters per second per second. It is assumed that the object started freefall on the surface of the body (i.e., the initial distance from the body's center of gravity was the radius of the body). Calculate the value of acceleration due to gravity on Venus's surface. It has enough volume to hold 63 Earths, but it only has 14 times our mass. Thus, the value of g on the Earth is g=9.8m/s 2. (b) A 2000-kilogram car is rounding a curve o. Saturn has an equatorial radius of 6.00 x 10 7 m and a mass of 5.67 x 10 26 kg. The value of g, however, does vary for each planet, star, moon, or other large body based on its size and mass. In the first equation above, g is referred to as the acceleration of gravity. These two gravitational parameters are related by the equation: Using this relationship, we can solve for the acceleration due to gravity on any planet so long as we know the planets size. In physics, gravity (from Latin gravitas 'weight') is a fundamental interaction which causes mutual attraction between all things with mass or energy [clarification needed].Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak . Similarly, every celestial object (star, planet, moon, etc) has its own gravitational field as its value of the acceleration due to gravity. Welcome! Acceleration due to gravityThe acceleration produced in the motion of a body under gravity is called Acceleration. Observe that the velocity-time data above reveal that the objects velocity is changing by 9.8 m/s each consecutive second. If one were to stand on it, they would simply sink until they eventually arrived at its (theorized) solid core.
