Lesson 14 (Rotation and Torque) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you!

Exercises in this video:
1. If you are standing on Earth’s equator (radius about 6380km), how fast are you going? What is your rotational velocity? What is your angular velocity?

2. A tiny cat, mass 0.50kg is clinging to the edge of a record spinning at 45rpm. If the radius of the record is 0.10m, what is the frictional force keeping that cat moving in a circle?

3. If Dianna, mass 60 kg, is standing on a scale on the equator, what does the scale actually read?

4. Dianna and Marie want to balance on a seesaw. But Marie has 3 times Dianna’s mass. How far away from Dianna should they move the fulcrum in order to balance the seesaw?

Consider Showing Some Love On Venmo @TheFinnMindset

A small sphere of mass M is suspended by a string of length L. The sphere is made to move in a horizontal circle of radius R at a constant speed, as shown above. The center of the circle is labeled point C, and the string makes angle θ0 with the vertical

Two students are discussing the motion of the sphere and make the following statements.
Student 1: None of the forces exerted on the sphere are in the direction of point C, the center of the circular path. Therefore, I don’t see how there can be a centripetal force exerted on the sphere to make it move in a circle.

Student 2: I see another problem. The tension force exerted by the string is at an angle from the vertical. Therefore, its vertical component must be less than the weight Mg of the sphere. That means the net force on the sphere has a downward vertical component, and the sphere should move downward as well as moving around in a circle.

(a) What is one aspect of Student 1’s reasoning that is incorrect? Explain why.
(b) What is one aspect of Student 2’s reasoning that is incorrect? Explain why.

Student 3 correctly derives two equations to relate the tension force FT to the net force Fnet and the other quantities.
(c) Explain how one of the equations can be used to challenge Student 1’s claim.
(d) Explain how one of the equations can be used to challenge Student 2’s claim.

The students observe that the radius R increases as the speed v of the sphere increases. Together, they derive the equation R = v L/g to calculate the radius of the circle R followed by the sphere if its speed is v.
(e) Regardless of whether this equation is correct or incorrect, does it plausibly model the students’ observation about the relationship between R and v? Why or why not?
(f) This equation does not correctly model the relationship between R and v if v is very fast. Explain why.

Instead of moving in a horizontal circle, the sphere now moves in a vertical plane so that it is a simple pendulum, as shown above. The maximum angle θmax that the string makes from the vertical can be assumed to be small. The graph below shows data for the square of the pendulum period T as a function of string length L.

Explain how the above graph would change under each of the following circumstances. Justify your answers.
(g) The mass of the sphere is increased.
(h) The maximum angle θmax is decreased.
(i) The pendulum is taken to the Moon.

Lesson 15 (Angular Momentum) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you!

More fun exploration of water spinning angular momentum demo from Steve Mould and Smarter Every Day: https://www.youtube.com/watch?v=M4-L8UgPkOk

Exercises in this video:
1. A box and a sphere are sliding and rolling, respectively, down a ramp. If they start from the same height, and we ignore friction on the box, which will reach the ground first?
What if it were a full soda can and an empty soda can?

2. A sphere of mass 4kg rolls down a ramp, starting with a height of 5 meters from the ground. How fast is the sphere rolling when it gets to the ground?

3. If every person on Earth ran around the equator in the same direction, what would their total angular momentum be? Use 65 kg as the average mass of the 7.8 billion people on Earth, and let them run at 5m/s.

4. Given 8 x 10³⁷ kg•m² as the Moment of Inertia of Earth, by how much would all those people running change the angular speed of the Earth?

Exercises in this video:
Problem1: The coefficient of friction between your car’s tires and concrete is 0.7. Your car’s mass is 1000kg. If you slam on your brakes and the tires lock, what is the magnitude of the sliding friction force acting while you slide? What is your acceleration?

Problem 2: You put your cow on a ramp. Moo. Then you tilt the ramp up, slowly. Just when your cow starts to slide, you measure the ramp angle as 34º. What is the coefficient of static friction between the cow and the ramp?

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

In this example problem, we show how to fill a molecular orbital diagram for a diatomic molecule and use molecular bond theory to compare bond order, bond strength, and magnetic properties (paramagnetic or diamagnetic).

Use molecular orbital theory to determine:
a.) the bond order of N2
b.) whether N2 is paramagnetic or diamagnetic
c.) order of increasing bond strength for N2, N22-, N2+

Learning Objective: Evaluate the number of valence electrons and core electrons from the electron configurations.

Topics: core electrons, valence electrons

Chemists need stoichiometry to make the scale of chemistry more understandable - Hank is here to explain why and to teach us how to use it.

In this tutorial video, we compare trends in the first ionization energy, second ionization energy, and third ionization energy for Na, Mg, and Si. Electron configurations are used to determine if a core electron or valance electron is being removed.
