About This Chapter
Mechanics - Chapter Summary and Learning Objectives
Motion, speed and velocity are all concepts that tie in with the idea of mechanics. It is these things that you'll study as you watch our mechanics video lessons. You'll get to learn about some basic concepts, along with studying some ideas more in-depth.
We have lessons that will introduce you to the ideas of speed, velocity and acceleration. You'll get to develop an understanding of these concepts, along with learning formulas that will allow you to calculate them. Additionally, we have a lesson covering the implications of mechanics on object, so that you will see the direct result of the concepts you have learned about.
Isaac Newton is not just the guy who sat in an unfortunate position under an apple tree and sustained a bump on the head. He is actually like a grandfather of science. He is an important figure who is responsible for the laws of motion, which have been formulated into three laws. You'll get to study these laws and learn about force, acceleration and the relationship between them as they relate to motion. In our lessons, we also take a look at how Newton's laws relate to the concepts of weight, mass and gravity.
Studying mechanics is made accessible and enjoyable, thanks to our helpful, straightforward animated video lessons. Our unique and engaging video lessons are taught by professors and other experts on the subject matter, and they're edited by experienced video professionals. Thanks for watching!
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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
