The Man Who Knew Infinity: Directed by Matt Brown. With Jeremy Irons, Dev Patel, Malcolm Sinclair, Raghuvir Joshi. The story of the life and academic career of the pioneer Indian mathematician, Srinivasa Ramanujan, and his friendship with his mentor, Professor G.H. Hardy.
The substitution you should make is that $mg = \frac{GM_{\rm E}m}{R^2}$ where $g$ is the value of the gravitational field strength at a distance $R$ from the centre of the Earth. Note that the value of $g$ is not constant.
Hidden Figures: Directed by Theodore Melfi. With Taraji P. Henson, Octavia Spencer, Janelle Monáe, Kevin Costner. Three female African-American mathematicians play a pivotal role in astronaut John Glenn's launch into orbit.
16 Αυγ 2021 · Show that the gravitational potential energy of an object of mass m at height h on Earth is given by \(PE_g = mgh\) Show how knowledge of the potential energy as a function of position can be used to simplify calculations and explain physical phenomena.
PE grav = m *• g • h In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
8 Αυγ 2019 · Here are 10 films, which prominently feature physics or physicists in a generally realistic and entertaining way.
The gravitational potential energy of an object is the 'stored energy' that the object has by being at that height. This is equivalent to its mass times the force of gravity, g (a defined constant of 9.8 m/s 2) times the height of the object. Potential energy = mass x gravity x height. Egrav = PE = mgh.
