Speed, Velocity & Acceleration

1. Speed, Velocity & Acceleration

Speed and velocity are not the same thing. Objects' speed and velocity can be identical or very different, depending on their directions of motion. In this article, learn more about these foundational physics concepts, including acceleration and free-falling objects.

Distinguishing Between Inertia and Mass

2. Distinguishing Between Inertia and Mass

Mass and inertia are both related to the amount of matter an object has, but they aren't exactly the same thing. In this video lesson, you'll see how mass affects an object's inertia, which in turn affects that object's motion.

What is Momentum? - Definition, Equation, Units & Principle

3. What is Momentum? - Definition, Equation, Units & Principle

People talk about momentum all the time; now you can discover what that word really means. Then learn about the principle of conservation of momentum and what it has to do with objects colliding.

Work: Definition, Characteristics, and Examples

4. Work: Definition, Characteristics, and Examples

Pushing a wall all day may feel like work, but unless you get that wall moving you're not doing any work according to the rules of physics. In this video lesson, you'll learn how work is defined as well as how to calculate the amount of work done on an object.

Work Done by a Variable Force

5. Work Done by a Variable Force

Doing work on an object is a simple concept: we apply a certain force over a certain distance. But in real life, that force is rarely constant. Therefore, we need to understand variable forces and be able to calculate them accurately.

Work-Energy Theorem: Definition and Application

6. Work-Energy Theorem: Definition and Application

Work and energy are closely related in physics. In this lesson, you'll learn what that relationship is as well as how we can apply it to various situations.

Objects with Two or More Forces: Finding the Total Force Result

7. Objects with Two or More Forces: Finding the Total Force Result

After watching this video, you will be able to explain what a force is and how it relates to motion, and find the total force result in a variety of force situations. A short quiz will follow.

Graphing Position & Speed vs Time: Practice Problems

8. Graphing Position & Speed vs Time: Practice Problems

After watching this video, you should be able to explain what position and speed are. You should also be able to plot position vs. time and speed vs. time graphs. A short quiz will follow.

What Are Simple Machines? - Definition, Types & Examples

9. What Are Simple Machines? - Definition, Types & Examples

If you need to move or lift a heavy object, it would be wise to use a simple machine. Though these devices are far from fancy or high-tech, they are extremely helpful for getting work done.
