Video: Test Trial of Catapult

In this video my group and I were test trying out our catapult at an approximate angle of 45 degrees which we hoped would of increased our distance. Projectile displacement is also present in this video, but also the force of gravity which then brings down the softball.

Dropping my iPhone

I am usually really careful when it comes to my phone, but accidents do happen and I dropped my phone on the cement ground. Since my phone dropped at free fall which means my phone was falling through the sole influence of gravity, it was accelerating vertically at 9.81 m/s^2 but with a initial velocity of zero. This is to say that my phone at free falling is changing by 9.81 m/s every second, but luckily enough my phone did not hit the ground hard enough to crack my screen. Also since my phone

Building a catapult

For physics we were given an assignment to build a catapult. In order to build a successful catapult we needed to take into account the angle of the arm of the catapult that was approximately measured at 45°. At 45°, where the arm of the catapult was suppose to be angled, when launched was suppose to give us the tallest possible height. Considering we were off on our measurements we were only able to get the softball at a constant distance of 8m. Lifting the catapult itself required force beca
