To weigh the Earth, we would need to know in which object's gravitational field we want to calculate the weight. The mass of the Earth, on the other hand, is a constant. Mass of Earth FAQs How is Earth mass calculated? Since scientists already know the radius of planet Earth, they us...
Weightis the result of gravity acting on mass: w = mg. The value of g on Earth's surface is 9.8 m/s3with units ofacceleration. To find the weight of something, simply multiply its mass by the value of the local gravitational field, and you get a result in newtons (N). For example...
Calculate the force of the Earth's gravity on a spacecraft 12,800 km (2 earth radii) above the Earth's surface if its mass is 1350 kg? Calculate the force of Earth's gravity on a spacecraft 12,800 km (2 Earth radii) abov...
- G is the gravitational constant, approximately 6.674×10−11N m2/kg2,- m1 is the mass of the first object (Sun),- m2 is the mass of the second object (Earth),- r is the distance between the centers of the two objects. 1. Identify the values: - Mass of the Sun, m1=2×10...
