Students will review:
This chapter helps students review the concepts in a Newton's Laws of Motion unit of a standard college physical science course. Topics covered include:
- Newton's three laws of motion
- Acceleration, speed and velocity
- Uniform circular motion
- Mass and weight
- Inertia and mass
- Projectile motion
- Balanced and unbalanced forces
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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Implications of Mechanics on Objects
Forces act on objects causing them to move. Mechanics is the field of science designated to the study of moving objects. This lesson describes how forces act on objects resulting in motion. Examples are used to describe how forces interact resulting in both simple and complex movement.
8. Uniform Circular Motion: Definition & Mathematics
After watching this lesson, you will be able to explain what uniform circular motion is, in terms of both acceleration and forces. You will also be able to use equations for centripetal force and acceleration to solve problems. A short quiz will follow.
9. 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.
10. 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.
11. 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.
12. Projectile Motion: Definition and Examples
A projectile is any object that is given an initial velocity and then follows a path determined entirely by gravity. In this lesson, we will introduce projectile motion and touch on a few key facts to keep in mind when working through these problems.
13. Projectile Motion Practice Problems
After watching this video lesson, you will know how to use the sets of equations that are used to solve projectile motion problems. Learn how to manipulate them to find the answer you need.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. Molecular Mass: Definition, Formula & Calculation
This lesson introduces the definitions of molecular mass and molar mass. Using information from the periodic table, you'll learn how to use the definitions to calculate either quantity. The lesson concludes with an actual calculation of molecular mass and molar mass.
