Question

Important formulas in the chapter force and laws of motion.

Answer 1

Equations of motion:

$v=u+at$

$s=ut+\frac{1}{2}\times a{t}^2$

$2as=v^2-u^2$

Force: $F=ma$

Gravitational force: $F=G\frac{m_1{m}_2}{d^2}$

Acceleration due to gravity: $g=G\frac{m}{R^2}$

Law of Conservation of linear momentum: $m_A{v}_A+m_B{v}_B=m_A{u}_A+m_B{u}_B$

Weight: $W=mg$

Equations of motion for motion under gravitational force:

$v=u+gt$

$h=ut+\frac{1}{2}\times g{t}^2$

$v^2-u^2=2gh$
