A-Level Physics Edexcel 9PH0

understand that a gravitational field (force field) is defined as a region where a mass experiences a force

understand that gravitational field strength is defined as $g = \dfrac{F}{m}$ and be able to use this equation

be able to use the equation $F = \dfrac{Gm_1m_2}{r^2}$ (Newton’s law of universal gravitation)

be able to derive and use the equation $g = \dfrac{Gm}{r^2}$ for the gravitational field due to a point mass

be able to use the equation $V_{grav} = \dfrac{-Gm}{r}$ for a radial gravitational field

be able to compare electric fields with gravitational fields

be able to apply Newton’s laws of motion and universal gravitation to orbital motion.
