AP Physics C: Electricity and Magnetism review of magnetic fields including: the basics of magnetic dipoles, ferromagnetic and paramagnetic materials, the Earth’s B field, magnetic permeability, the magnetic force on a moving charge, the...

The definite integral is defined using work. Several simple math examples are worked through. 3 different examples determining area “under” curve are solved. The positive and negative value of area “under” a curve is demonstrated. Want...

Defining the vector cross product.

When we place a 1.00 kg mass on a spring, the end of the spring moves from the 34.4 cm mark to the 30.2 cm mark and comes to rest. (a) What is the spring constant of the spring? (b) What is the work done by the spring on the mass? Want...

It discusses different types of vectors – zero, unit, co-initial, equal and negative.

Learn how to determine the dot product of vectors. The dot product of two vectors also called the scalar product of the vectors is the sum of the product of the components of the vectors in each direction. When the magnitudes of the...

How to tell if the two vectors are parallel, orthogonal or neither

In this video, we learn how to determine the electric flux through a sphere that surrounds a positive point charge. We start by discussing the equation for electric flux and how it applies to uniform electric fields. We then move on to...

In this video series you will learn multiple math operations. I teach in front of a live classroom showing my students how to solve math problems step by step. My math tutorials should be used to review previous lessons, complete your...

Example: A 0.280 kg object has a position described by the function, position as a function of time equals 5.00 t^3 - 8.00 t^2 - 30.0 t meters. What is the net power being delivered to the object at 2.00 seconds? Want Lecture
