Newton’s law (AQA A-Level Physics): Flashcards

Always attractive, acts on objects with mass

Directly proportional to product of masses

Inversely proportional to square of distance

Force becomes one-fourth as strong

$F = \frac{G \cdot m_1 \cdot m_2}{r^2}$

$6.674 \times 10^{-11}$ $\text{Nm}^2/\text{kg}^2$

Distance between centres of the two masses

Force becomes one-ninth as strong

Equal magnitude, opposite direction between objects

Points towards the centre of each mass
