1. What Is Motion? - Definition & Equations
After watching this video, you will be able to explain what motion is and use basic equations of motion to solve problems. A short quiz will follow to test your knowledge.
2. 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.
3. 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.
4. Using Position vs. Time Graphs to Describe Motion
Describing motion with graphs can be a simple, yet powerful tool in your physics arsenal. In this lesson, we begin by looking at the basic position vs. time graph.
5. Determining Slope for Position vs. Time Graphs
Simply looking at a position vs. time graph can tell you a lot about straight line motion, but doing a few basic calculations can tell you even more. In this lesson, we will learn how to use the slope of the line to determine average velocity.
6. What is Acceleration? - Definition and Formula
This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.
7. Determining the Acceleration of an Object
Acceleration is a change in an object's state of motion. A few variables need to be identified to calculate an object's acceleration, but once we have those values, we can put them into a simple equation to find out how quickly or slowly an object's velocity is changing.
8. Determining Acceleration Using the Slope of a Velocity vs. Time Graph
In this lesson, we will learn how to use the slope of the line on a velocity vs. time graph to calculate the acceleration of an object in straight line motion.
9. Force: Definition and Types
Force is everywhere and it comes in a variety of sizes, directions, and types. In this video lesson, you'll identify force as well the different types of force that objects may experience.
10. Forces: Balanced and Unbalanced
Forces are needed to start or stop an object's motion, but can also be involved when an object is at rest or already traveling at constant velocity. In this video lesson, you'll identify the difference between balanced and unbalanced forces, understanding how they affect the movement of objects.
