About This Chapter
1. Speed and Velocity: Concepts and Formulas
Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.
2. Acceleration: Definition, Equation and Examples
Acceleration can be a tricky topic for many students who tend to get hung up on an object's speed. In this lesson, we will explore the common aspects of acceleration and why speed is not always important.
3. Distance and Displacement in Physics: Definition and Examples
Distance and displacement might seem like similar terms but in physics, understanding the difference can mean getting a question right instead of wrong. In this lesson, we will define these terms and illustrate how easy it is to confuse the two.
4. Scalars and Vectors: Definition and Difference
In this lesson, we will examine scalars and vectors, learn why it is important to know the difference between the two and why remembering to add a direction to many of your exam answers could be the reason you get it right or wrong.
5. Newton's Laws of Force & Motion
Newton's laws of motion explain why we observe the motion we do in the world around us - they explain how forces work. In this lesson, we take a look at each of Newton's laws one by one.
6. Newton's Law of Gravitation: Definition & Examples
This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.
7. How to Use Free-Body Diagrams to Solve Motion Problems
The free-body diagram is a powerful way to analyze forces in a scenario. This lesson describes the rules you should follow when using a free-body diagram, and includes multiple examples modeling how to solve force problems.
8. 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.
9. 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.
