About This Chapter
Dimensions of Motion in Physics - Chapter Summary
This chapter takes you through a multitude of concepts and measurements key to the motion dimensions in physics. It breaks down topics one by one so you can firmly grasp each of them before moving on to another. By the end of this chapter, you can expect to have solidified and enhanced your understanding of:
- Formulas and equations for speed, velocity, and acceleration
- Distance and displacement
- Velocity as compared with time
- Linear momentum and its conservation
- Momentum and impulse
- Vectors and scalars
Review the content through a video or transcript of the material. Videos are generally between 5 to 10 minutes long and they can be watched via your tablet, smartphone or other mobile device. If you ever get stuck on a topic, you'll never be alone in your uncertainty because our instructors available to answer your questions through the help tab.
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. 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.
5. Linear Momentum: Definition, Equation, and Examples
Any moving object has momentum, but how much momentum it has depends on its mass and velocity. In this lesson, you'll identify linear momentum, as well as see examples of how an object's momentum is affected by mass and velocity.
6. 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.
