This problem is about the relationship between frequency and radius for a charged particle moving in a circle in a constant magnetic field.

This problem is about finding the kinetic energy of an electron in orbit around a proton

This Free Response Question includes the following concepts: Free Body Diagrams (or Force Diagrams), Static and Kinetic Friction, Tension, Force Normal, Force of Gravity, Newton's Second Law (many times), a Multiple Bock System and a...

An object has three forces acting on it. We determine the direction of the acceleration, the mass, and the final velocity. Want Lecture Notes?f='http://www.flippingphysics.com/unit-v...' target='_blank' rel='nofollow'>Notes?​ This is...

Identifying the spring force, acceleration, and velocity at the end positions and equilibrium position of simple harmonic motion. Amplitude is also defined and shown.

Enjoy learning from Billy as he solves a problem using Work due to Friction equals Change in Mechanical Energy.

Gravitational lensing occurs when a huge amount of matter, like a star, galaxy, or cluster of galaxies, creates a powerful gravitational field around it, strong enough to bend the light coming from distant galaxies (behind...

Deriving the Parallel Axis Theorem for moment of inertia or rotational inertia.

As we continue our search for earth-like, potentially habitable worlds, we come across an interesting triple-star system called Gliese 667. The smallest of these three stars, Gliese 667 C, is a red dwarf with several planets, one of...

This is a lecture video on particle motion of gases, explaining how the temperature of a gas affects the motion of its particles and its pressure. The video starts by describing the kinetic energy of gas particles and how they collide...

Calculus based review and comparison of the linear and rotational equations which are in the AP Physics C mechanics curriculum. Topics include: displacement, velocity, acceleration, uniformly accelerated motion, uniformly angularly...

In this video, the concept of matter is explored. The video also introduces the idea of physical properties, which can be observed or measured without changing the makeup of the matter. This video is part of the 9-part series, Describing...

When the forces in a free body diagram don’t change students often think that Newton’s Second Law will yield the same results. This demonstration shows that is not true. This is a step-by-step analysis of tension force as a function of...

The undergraduate curriculum for physics and electrical engineering have some similarities that students may not be aware of. With both majors you get to see circuits, basics physics concepts, and even...

A 25 kg child is sitting on the edge of a merry-go-round. The merry-go-round has a mass of 255 kg and is rotating at 2.0 radians per second. The child crawls to the middle of the merry-go-round. What is the final angular speed of the...

In this video, we’re going to learn about the loss of mass in a chemical reaction, how it happens and why we measure this. The total MASS of reactants will be the same as that of the products, as mass is always conserved in a chemical...

Long Jane Silver and Senor Ortega analysed the soil sample and saved the cocoa trees! But something’s not right… Did they perform the wrong steps? Was their sample contaminated? This lesson will assess the accuracy, reliability and...

We use Newton’s Second Law and Uniformly Accelerated Motion to experimentally determine the Static Coefficient of Friction between Tires and Snow.
