Physics Bowl: block A is traveling on an inclined plane that has non-negligible friction. It is given an initial velocity v, travels up the incline, momentarily comes to rest, then slides down the incline. Is the acceleration greater on its way up the incline or down the incline?

Physics bowl: how fast is the object in the previous question moving at the bottom of the incline?

Physics Bowl: an object of mass 2 kg starts at the top of a ramp with non-negligible friction that is 3 m high. If the force of friction did -10 J of work on the object, how much kinetic energy does it have at the bottom of the ramp?

Physics Bowl: what does it mean when something is “rolling without slipping”?

Physics Bowl: what equation would I use for angular momentum of an object moving with a linear velocity?

Physics Bowl: Ball A and B are at the top of a table. Ball A is thrown downward with a velocity v. Ball B is thrown horizontally with a velocity v. Which ball reaches the ground first and which one has a greater velocity when it hits the ground?

Physics Bowl: a disk, with rotational inertia I is spinning with an angular velocity ω. A second disk, with rotational inertia 2I is placed on top of the first disk. With what angular velocity will the pair of disks spin with afterwards?

Physics Bowl: use parallel axis theorem to solve for the rotational inertia of a rod about its end if the rotational inertia of the rod about its center is 1/12 ML^2

Physics Bowl: a ball is launched from the ground at a velocity v, at an angle θ with the horizontal. What is the velocity and the acceleration at the top of the projectile?

PB: Ball A, B, and C are at the top of a cliff of height h. Ball A thrown vertically upward with a velocity v, ball B is thrown horizontally with a velocity v and ball C is thrown vertically downward with a velocity v. Compare the time of flight for each and their final speeds.

@matthewlardi wooooooo! Still got it🥳

@ITphysics Both balls will reach the ground at the same time. Both fall vertically at the same acceleration due to gravity. Still got it

PB: ball A is rolled horizontally off of a table. Ball B is dropped from the same height. Which ball will reach the ground first and why?

Physics Bowl: what is conserved in an elastic collision?

So proud! 🤩

New project 🚨 Robotics students made a light theremin🎶

Island Trees Bulldogs Olivia Carbonaro, Kayla Portes, Taha El Mlilass and Rich Montalvo (along with Coaches Papach and Hastings) took part in Sec. VIII's Unity, Civility and Sportsmanship conference. A great day of teamwork for Nassau's student-athletes. @Sec_VIII_Ath

Robotics students making a color mixing lamp using phototransistors. The LED changes colors and brightness based on the surrounding light.

PB: what does it mean for an object to be in free fall?

Our end of PARP WAS out of this world! Thanks to ⁦@MsRadcliffe1⁩ and ⁦@ITphysics⁩ collaboration, we celebrated from MARS! The students met their reading goal and I was blasted into the universe! A special shout out to period 6 HS robotics students!
