Projectile motion is the motion that is made by a projectile that is propelled by a projector of sorts which is usually things such as sports balls, bullets, arrows,people,planes/helicopters and any other object that is either thrown or propelled into the air and has a flight path.
What are the three parts of projectile motion ?
Height of release - for things like sports(shot put) the height of an athlete can effect the projectile motion of the shot put. For example if two athletes were to throw a shot put at the same height, angle and speed but one was much taller than the other the taller athlete's shot put would travel a longer distance
Angle of release - The angle of release is also in-cooperated into projectile motion because for shot put if an athlete through a shot put at two high of an angle (for example 45 degrees) the shot put would not go it's full potential of distance. The recommended angle of release for a shot putter is in between 31 - 38 degrees because at this angle the shot put has the potential to go it's maximum distance with also the right amount of height and speed.
Speed of release - The speed of release is also important because for a sport like badminton the speed of release must be much lower to sports such as volleyball because the projectile (shuttlecock) is much lighter than any other projectile used in sport. But the speed of release is important because even for badminton you need to make sure you use the right amount of speed for every hit to find a way to score.
Explain the activity this morning relating to projectile motion.
The activity we did this morning was that our teacher gave us a rubber band and a piece of paper and told us to try propel the piece of paper using the rubber band and that we could screw up, rip up and fold the paper any way we wanted to and try get the paper as far across the room as possible. But most of us didn't succeed in doing it the right way by tilting it up to change the angle of release and to change the height of release as well as the speed of release.

This is an incredibly in depth reflection of our lesson and of the biomechanical principle - well done Jack! I love how you have taken the time to explore each component of projectile motion, this is great rewindable for learning for yourself and your peers. I like how you've included a picture to show a flight path, have you considered embedding videos into your future posts? Excited to see more reflections like this one!
This is exactly what we teach in Level 2 Physics. And I would like to show this blog post to our Y12 Physics students. Well done !
