9.2.2.3.1  solve problems and analyse information to calculate the actual velocity of a projectile from its horizontal and vertical components using : $$\begin{array}{cc}{v}_{x}^{2}& ={u}_{x}^{2}\\ v& =u+at\\ {v}_{y}^{2}& ={u}_{y}^{2}+2{a}_{y}\Delta y\\ \Delta x& ={u}_{x}t\\ \Delta y& ={u}_{y}t+\frac{1}{2}{a}_{y}{t}^{2}\end{array}$$

9.2.2.3.2  perform a firsthand investigation, gather information and analyse data to calculate initial and final velocity, maximum height reached, range and time of flight of a projectile for a range of situations by using simulations, data loggers and computer analysis

9.2.2.3.3 identify data sources, gather, analyse and present information on the contribution of one of the following to the development of space exploration: Tsiolkovsky, Oberth, Goddard, EsnaultPelterie, O’Neill or von Braun

9.2.2.3.4  solve problems and analyse information to calculate the centripetal force acting on a satellite undergoing uniform circular motion about the Earth using: $$F=\frac{m{v}^{2}}{r}$$

9.2.2.3.5  solve problems and analyse information using: $$\frac{{r}^{3}}{{T}^{2}}=\frac{GM}{4{\pi}^{2}}$$
