WebOn Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth ’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. WebAug 15, 2024 · I ≈ 9.736 × 1037kgm2 Explanation: If we think of the earth as a solid sphere rotating about its center, the moment of inertia is given by: I = 2 5M R2 where M is the mass of the earth and R is its radius We are given the following information: ↦ M = 5.98 ×1024kg ↦ R = 6.38 × 106m Substituting these values into the equation above:

WebΔ U = U orbit − U Earth = − G M E m R E + 400 km − ( − G M E m R E). We insert the values m = 9000 kg, M E = 5.96 × 10 24 kg, R E = 6.37 × 10 6 m and convert 400 km into 4.00 × 10 5 m. We find Δ U = 3.32 × 10 10 J. It is positive, indicating an increase in potential energy, as we would expect. Significance WebNear the surface of the Earth, the acceleration due to gravity g = 9.807 m/s 2 (meters per second squared, which might be thought of as "meters per second, per second"; or 32.18 ft/s 2 as "feet per second per second") approximately. A coherent set of units for g, d, t and v is essential. Assuming SI units, g is measured in meters per second squared, so d must … florist near westfield in
