Yesterday we looked at what happens to a projectile when it is launched horizontally. However, more generally a projectile could be launched at any angle. Below shows what we need to do to solve problems that involve projectiles launched at an angle to the horizontal. The PowerPoint can also be found here with an example problem to be solved. At the end of the PowerPoint is a task to produce a scale diagram of a projectile's trajectory (i.e. the path that it takes). Any projectile that moves under the influence of gravity will show a parabolic path. This is where the y-displacement is proportional to the square of the x-displacement. You can calculate the values for the x-displacement using the simple equation: dist. = speed x time. The vertical displacement values can be found using the equation s = 1/2 at^2. Where a = -10m/s^2 (for ease of calculation!). Below is a diagram of the graph produced in excel.
