Electric Force: Definition & Equation

1. Electric Force: Definition & Equation

The electric force is one of the most powerful, fundamental forces in the universe. In this lesson, we will learn how charged objects exert electric forces on each other and how to calculate the strength of that force.

The Lorentz Force Law

2. The Lorentz Force Law

Electric and magnetic fields are both capable of creating forces on charged particles. In this lesson you'll learn how these two forces are related through the Lorentz force law.

How Magnetic Forces Affect Moving Charges

3. How Magnetic Forces Affect Moving Charges

A magnetic field exerts a force on a moving charged particle in ways that you might not expect. In this lesson, we're going to look at the direction of this force and the factors that affect its strength.

Calculating Motion in Magnetic Fields: Formula & Practice

4. Calculating Motion in Magnetic Fields: Formula & Practice

Magnetic fields exert a force on moving charged particles. In this lesson, we will focus on the formula for the magnetic centripetal force acting on an electron. We will also work through some example problems.

Gravitational Force: Definition, Equation & Examples

5. Gravitational Force: Definition, Equation & Examples

You probably have an idea of what gravity is, but did you know that you, right now, are actually pulling on every other object in the universe? Find out more about the gravitational force and learn an equation to calculate its pull on other objects.

Force vs. Time & Force vs. Distance Graphs

6. Force vs. Time & Force vs. Distance Graphs

In this lesson, you'll find out how to determine impulse from a force-time graph and speed from a distance-time graph. You'll also learn how to describe the general shape of these graphs for simple harmonic motion.

Change in Gravitational Potential Energy: Graphs & Analysis

7. Change in Gravitational Potential Energy: Graphs & Analysis

We'll explore how to find an object's change in gravitational potential energy as it moves in relation to a zero reference point. We'll do this visually with gravitational force vs. distance graphs and gravitational field vs. distance graphs.
