After watching this lesson, you will be able to support your discussion of Julius Caesar’s themes with detailed textual analysis!

This lesson unpacks the most famous and significant quotes uttered by Brutus, the main character....

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...

Once we get the hang of stoichiometric calculations, we get a curve ball. Limiting reagents? Not all of the reactants will react? We might not get as much product as we expect? Let's practice identifying the limiting reagent, calculating...

The video discusses an experiment carried out by Harry to investigate how the temperature of crushed ice varies as it melts. Harry placed some crushed ice in a boiling tube and then placed the boiling tube in a beaker of water. The...

In this video we look at what the weighted average is.

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

How to find the center of mass of an irregularly shaped, flat object.

This video shows the process for solving the problem presented in SATs 2022 Paper 2 Q12, which involves ordering masses of parcels. Students will learn how to convert between different units of mass, such as converting kilograms to grams...

The video explains the concept of empirical formula in chemistry. The video also talks about how to convert the molecular formula into the empirical formula and vice versa. The video presents examples of how to determine the empirical...

Watch the final part of the 'using moles' videos, to complete your understanding of the chemical calculations topic. Avogadro’s number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in chemical calculations. For...

Simple Harmonic Motion is introduced and demonstrated using a horizontal mass-spring system.

Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video!

The video discusses the concept of relative formula mass and how to calculate it using examples of simple and more complex compounds. The periodic table is used to find the atomic masses of the elements in the compound, which are then...

When you take a shot on a pool table or tackle someone in a football game, you're participating in a collision. But the two events we just mentioned are totally different kinds of collisions! We have to learn the varieties and what they...

Kinetic energy and elastic potential energy as functions of time graphs for a horizontal mass-spring system in simple harmonic motion are demonstrated. Conservation of energy is shown.

The video explains the process of finding the formula of a metal oxide through experimental means. The presenter explains two methods of determining the formula - forming the metal oxide from the metal and reducing the metal oxide to...

This video is about atomic structure and covers the three particles that make up an atom - protons, neutrons, and electrons. The video discusses their properties, such as charge and relative mass, and where they are located within the...

This nugget describes the nucleus of an atom. It talks about the various aspects of a nucleus like atomic number, atomic mass unit, isotopes and isobars, with examples.
