The equation for the force of gravity is. Depending on the relative direction of motion of the planet and the spacecraft, a gravity assist can either speed up, slow down, or merely change the direction of the spacecraft. This is usually used to describe the areas in the Solar System where planets dominate the orbits of surrounding objects such as moons, despite the presence of the much more massive but distant Sun. calculate the gravity of a planet if a 4 meter pendulum has a period of 2 seconds. Read more about Pluto's new status at our sister site, Fact Monster. So, if you know your weight on Earth and the surface gravity on Earth, you can calculate your mass.You can then calculate your weight on any other planet by using the surface gravity of that planet in the same equation. To calculate escape velocity, multiply 2 times G times M, then divide that by r, and take the square root of the result. where, G - Gravitational constant (6.67*10-11 Newton-meter 2 / kg 2) M - mass of the planet or object on which you calculate surf. There’s two answers to this question: whether you mean gravitation acceleration or gravitational force. The following tool tells you what the scales would read on other worlds. Gravity equation calculator solving for planet mass given universal gravitational ... AJ Design ☰ Math Geometry Physics Force Fluid Mechanics Finance Loan Calculator. The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space. and it holds true no matter how far apart two masses are. Solving for planet mass.
