Distance and Displacement in Physics: Definition and Examples

1. 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.

Graphing the Motion of Objects: Physics Lab

2. Graphing the Motion of Objects: Physics Lab

After watching this lesson, you will be able to measure the motion of an object and plot position-time and velocity-time graphs based on your data. A short quiz will follow.

Using Position vs. Time Graphs to Describe Motion

3. 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.

Speed and Velocity: Difference and Examples

4. Speed and Velocity: Difference and Examples

Is it possible to drive with a speed of 100 mph but a velocity of 0? In this lesson, we will examine the difference between speed and velocity and use that information to answer this question.

Determining Slope for Position vs. Time Graphs

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.

Using Velocity vs. Time Graphs to Describe Motion

6. Using Velocity vs. Time Graphs to Describe Motion

In this lesson, we will look at an example of a velocity vs. time graph. By examining the shape of the graph, it is possible to accurately describe the motion of an object, even if that motion is very complex.

Velocity vs. Time: Determining Displacement of an Object

7. Velocity vs. Time: Determining Displacement of an Object

There is a lot of information you can determine by looking at a velocity vs. time graph. In this lesson, we will use a little geometry to calculate the displacement of the object represented by the graph.

Average vs. Instantaneous Velocity: Difference & Uses

8. Average vs. Instantaneous Velocity: Difference & Uses

What is the difference between average and instantaneous velocity? How do you calculate each of these and when do you use them? This lesson will help you understand these common terms and know when to use each one.

Acceleration: Definition, Equation and Examples

9. 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.

Determining Acceleration Using the Slope of a Velocity vs. Time Graph

10. 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.

Understanding Graphs of Motion: Giving Qualitative Descriptions

11. Understanding Graphs of Motion: Giving Qualitative Descriptions

You can just look at graphs of straight line motion and accurately describe how that object is moving. In this lesson, we will investigate the basic shapes the graphs can take and what conclusions you can draw from these shapes.

Overview of Graphs of Free Fall Motion

12. Overview of Graphs of Free Fall Motion

After completing this lesson, you will be able to explain what free fall motion is, and identify and draw displacement, velocity, and acceleration-time graphs for free fall motion.
