OBHS Physics Club

posting the cool stuff done in AP physics and the physics club. which is all the stuff.

r.i.p. this account, would like to dedicate this last post to @CoachRock_IW . shoutout mr torok u enjoyed physics more than most of us here no cap, love u

the hanging masses are attached to the yo-yo looking thing on the right...notice how the yo-yo doesn’t not fall like the masses, but instead spins. that’s b/c the tension in the rope is equal to its force of weight, making it unable to accelerate downwards but instead spin

the AP physics class made apple cider!!!!!!!!! lots of hard work cutting, mashing, and pressing probably over 100 apples! please buy our cider we did not suffer for like 3 hours for nothing ;((( 50¢ a cup on sale room 265 <3

have you ever made a half-Atwood machine, added an incline plane with a steel ball on top, and wondered: what mass of the hanging weight will make it so that the ball does not roll off the plane? we did. so we took matters into our own hands and found out les goo .

yay! using knowledge of projectile motion, AP physics students calculated the exact angle to successfully hit the water bottle while at the same not killing mr goodman!!!!

AP physics students’ working motors! ask one of us to explain to u. it’s pretty cool. then u are mandated to take physics afterwards

if u look into the telescope when it’s pointed at the sun, ur eyes would quite literally burn, so we projected an image of the sun onto the box. sometimes u can even see sunspots. Bc earth is rotating, the image will MOVE, so then we can roughly calculate earth’s rotational speed

predicting earth’s rate of rotation using an image of the sun!

dropping a steel and ping pong ball to study air resistance. each student films the drop in slow motion at different increments of the marked wall (we will never tell u how we marked it.) evan’s doing a nice t-pose and nina’s on the ground behind nick filming the point of impact

afterwards, we measured the voltage of the car’s battery. PHYSICS IS FUN!

AP physics explore the regenerative braking of robert’s car as a demo! the car decelerates by converting its kinetic energy to a form of energy that can be used right away or stored until needed.
