About This Chapter
1. Newton's First Law of Motion: Examples of the Effect of Force on Motion
This lesson describes Newton's first law of motion, also known as the law of inertia. The interaction between force and motion is explained. Several examples are used to discuss the implications of this law on earth and in space.
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.
3. Mass and Weight: Differences and Calculations
We often talk about mass and weight as if they are the same. While they are proportional to each other, they are not, in fact, the same. In this video lesson, you will learn to distinguish between the two, as well as convert one to the other.
4. State of Motion and Velocity
An object's state of motion describes how it is moving. But there are many ways we can describe motion, such as speed and velocity. This motion is relative to other objects around it, such as the earth, the sun, and even other stars in our galaxy.
5. 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.
6. Free-Body Diagrams
Forces that act on an object can be drawn through special vector diagrams called free-body diagrams. In this video lesson you'll identify how to correctly represent forces in a free-body diagram through vector arrows and force labels.
7. Force vs. Time & Force vs. Distance Graphs
In this lesson, you'll find out how to determine impulse from a force-time graph and speed from a distance-time graph. You'll also learn how to describe the general shape of these graphs for simple harmonic motion.
8. Net Force: Definition and Calculations
Because forces are vectors, we can't simply add them up to get a total amount of force on an object. Instead, we calculate the net force, which is important to understand because it tells us about an object's state of motion.
9. Newton's Second Law of Motion: The Relationship Between Force and Acceleration
This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.
10. 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.
11. Determining the Individual Forces Acting Upon an Object
Objects constantly have forces acting on them whether they are moving or at rest. In this video lesson, you'll understand how to identify the individual forces acting on an object by reviewing the different types of forces and the use of free-body diagrams.
12. Newton's Third Law of Motion: Examples of the Relationship Between Two Forces
This lesson describes Newton's third law of motion. Examples are provided to illustrate how interacting objects experience forces. The lesson explains how objects accelerate as a result of force. Applications of Newton's third law are illustrated in nature, machines, and space.
13. Newton's Laws and Weight, Mass & Gravity
Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.
14. Friction: Definition and Types
You experience friction all the time, and you should be glad you do! Friction helps keep stationary objects in place as well as slow moving objects down as they slide across a surface. This lesson identifies what friction is and explains the two ways we find this force on earth.
