An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

Bridges... bridges, bridges, bridges. We talk a lot about bridges in Physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini...

Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to...

Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of...

This content analyzes a physics problem involving a ball connected by two strings to a rotating vertical rod, undergoing circular motion. It demonstrates how to calculate the tension in the lower string, the net force on the ball, and...

This content delves into the physics of a falling cylindrical chimney, treating it as a thin rod rotating about its base. It uses energy conservation to determine the angular velocity and subsequently calculates the radial and tangential...

A particle accelerator is a machine that accelerates particles. More specifically, it accelerates elementary particles, like protons and electrons, at extremely high speeds—almost 99.99% of the speed of light. These particles are then...

This review of circular motion explains key concepts such as tangential velocity, centripetal acceleration, and how objects move in circular paths. Tangential velocity is always perpendicular to the radius, while centripetal...

Delve into the mass spectrometer, a crucial tool for understanding particles and their properties. Consisting of a velocity selector and a deflection chamber, it begins with charges entering the crossed fields of magnetic and electric...

If you're given the parametric equations describing the path of a particle. How do you find out the accelerations in the normal and tangential direction? Find the velocity and you know the tangential direction. Find the acceleration and...

Circular Motion proof

What is the magnitude of the acceleration of a ball traveling around a circular path if it's constrained to have a constant vertical velocity? Always start these problems by doing a velocity analysis, then finish it by doing an...

circular motion problem 2

Here we solve for the velocity of a block as it's sliding up a circular hill using energy methods 1) Find work done by external forces (it's 0). 2) Notice there is negligible rotation so the kinetic energy is just 0.5 m (v2^2 - v1^2). 3)...

In this video, the sport of Hammer throw is explained and how physics plays a crucial role in achieving a long-distance throw. The concept of centripetal force and how it affects circular motion is discussed with the help of an...

A block is sliding down a circular path and colliding with a spring. What is the maximum compression of the spring?

Here I derive the most generic equations of motion (position, velocity & acceleration) for a continuous curve. The calculus is pretty involved so I definitely recommend you hit up your math textbook first!

Here we solve for the velocity of a disk as it's rolling up a circular hill using energy methods 1) Find work done by external forces (it's 0). 2) Notice there is rotation so the kinetic energy is 0.5 m (v2^2 - v1^2) + 0.5 I (w2^2 -...
