Thin Rod example of the Parallel Axis Theorem

A basic rotational form of Newton’s Second Law problem with only one force.

Review of all of the Dynamics topics covered in the AP Physics 1 curriculum.

The second moment of area (or moment of inertia of area) about the x or y axis can be found using the integral of y^2 dA and x^2 dA respectively. <b<br/>r/>

The larger the moment of inertia, the greater resistance to bending / rotation.

The bar is purely rotating about the pin support. However, we can view this phenomenon as simultaneously rotating about the center of mass while the center of mass is moving in a circular path. This means we have to include both the...

A formal proof of the parallel axis theorem. It's really useful for finding moments of inertia of composite objects and also objects which aren't rotating around the center of mass.

This live-action video program is about the word mass. The program is designed to reinforce and support a student's comprehension and retention of the word mass through use of video footage, photographs, diagrams and colorful, animated...

To find the second moment of area about the x axis use

Ix = /int y

To find the second moment of area about
the y axis use<

br/>Iy = /int x^2 dA

In this video I solve this problem using the double integral...

Introduction to the Rigid Rotor Model: Wavefunction? Energy?

The results are in – gravity is weaker than it should be! Lotus is certain that someone is digging a giant cave underneath the Big Apple, but Mark isn’t convinced. Who do you think is correct? This lesson will assess the accuracy,...

This is one dynamics example problem you could expect to see on your exam. It tests a variety of different topics.<br/>
i) a_x =<br/> 2.21 m/s^2
ii) V_2 = 2.97 m/s downwards (onc<br/>e moved down 2 meters)
iii) T_1 = 40.38N and T_2 = 76.01N

Moments and Forces summary

In this video, we learn about ancient astronomers' beliefs regarding the solar system and how they believed Earth was the center with the sun and other bodies revolving around it. It also highlights the role of gravity in keeping the...

Who ever said physics was boring?! With Animated Physics, little ones will have a blast as they explore topics like gravity, inertia, buoyancy and more! Using real-life examples and engaging visuals, this is the perfect introduction to...

This video explains the concept of inertia and how it is quantified in terms of an object's mass and acceleration. The video uses examples of cars and lorries to demonstrate how larger masses require greater forces to be accelerated at...

Three 20.0-gram masses are 9.4 cm from an axis of rotation and rotating at 152 revolutions per minute. What is the moment of inertia of the three-object system? The strings holding the masses are of negligible mass. Rotational Kinetic...

Newton's First Law | Force & Motion | Physics | FuseSchool In Physics we have three fundamental Laws of Motion created by Sir Isaac Newton way back in the 17th century. Today we are looking at the first law of motion, sometimes called...
