Unit 4 Projectile Motion

Today we were introduced to projectile motion. A projectile is any object that is only under the influence of gravity. An example is a bullet after it's been fired from a gun. We also learned about 2 dimensional kinematics. The most important concept was the Vegas Rule which states that "What happens in Vegas stays in Vegas". Or in Physics terms "What happens on the (x or y axes) stays on the (x or y axes)". This is because the axes are independent, meaning objects can be moving horizontally and vertically at the same time. An example is when you throw a ball to someone else, the ball is moving both up then down and forwards at the same time.


This is a picture of me at air riflery. We shoot pellets which is kind of like a bullet. After it's fired form the gun the pellet becomes a projectile because it's only under the influence of gravity as it travels through the air.

  2. I really like the way you summarized it for me, it helped it make more sense! I also thought it was cool that you didn't just take a picture off the internet but used one of yourself. I also didn't know you did air riflery, cool!
