# Ch 41: Mechanics Overview

### About This Chapter

## Mechanics Overview - Chapter Summary

This chapter focuses on all aspects of mechanics, covering such topics as motion, momentum, friction and velocity. These lessons will address relevant laws, equations, theorems and formulas relating to these concepts and how each of these are applied. Upon completion of your review, you should be able to:

- Discuss the laws of motion
- Calculate velocity in math problems
- Describe relative velocity in kinematics
- Use examples to describe the composition of velocity and acceleration
- Define projectile motion and conservation of momentum
- Understand the loss of energy resulting from the impact of two smooth bodies
- Understand details about coplanar force
- Solve problems relating to concurrent and parallel forces
- Identify the properties of a centroid
- Apply the formula to calculate static friction

These complex topics are simplified by expert instructors so you can ensure your full understanding of the material covered in these lessons. Access lessons at any time, on any device, so you can enjoy a self-paced and convenient learning experience. Demonstrate mastery of each subject and identify any areas in which you need further review by taking self-assessment quizzes after viewing or reading a lesson.

### 1. What is Motion? - Definition & Laws

Motion is the act of moving and plays a huge role in the study of physics. This lesson walks through important terms and the laws of motion that guide the study of motion.

### 2. Velocity in Math: Definition, Equation & Problems

Velocity in math is similar to speed, with only one difference. Learn what that difference is, how to write velocity, and how to calculate velocity problems.

### 3. Understanding Relative Velocity in Kinematics

After completing this lesson, you will be able to explain what relative velocity is in kinematics and calculate relative velocities in basic situations. A short quiz will follow the lesson summary.

### 4. Composition of Velocity & Acceleration

Velocity is how fast something is moving in a specific direction. Acceleration is the change in velocity in a specific direction. Both velocity and acceleration are relative. In this lesson, we will explore how velocities and accelerations are relative to other objects with velocities and accelerations.

### 5. Gravity & Projectile Motion: Physics Lab

After watching this video, you will be able to define projectile motion and use the equations of projectile motion to make predictions about motion in a real-life scenario. A short quiz will follow.

### 6. Conservation of Momentum: Physics Lab

After completing this lab, you will be able to explain what conservation of momentum is and conduct an experiment to demonstrate conservation of momentum. You can also take the short quiz to test your knowledge.

### 7. Composition & Equilibrium of Coplanar Forces

Forces are pushes or pulls on a mass. In this lesson, we will investigate what coplanar forces are, and how the composition of coplanar forces can be balanced, so that a mass is in equilibrium.

### 8. Concurrent & Parallel Forces in Physics

When multiple forces are applied to an object, they may be either concurrent or parallel. In this lesson, learn how to identify concurrent and parallel forces and how to find the resultant of a concurrent or parallel force system.

### 9. Centroid: Definition, Theorem & Formula

Have you ever wondered how to find the balancing point of a triangle? The answer can be found in this lesson on the centroid of a triangle! We'll learn how medians are used to locate the centroid and then discuss its various properties.

### 10. Static Friction: Definition, Formula & Examples

In this lesson you will learn what static friction is and how it is different from kinetic friction. You will also learn a formula that can be used to calculate the force of static friction and see some examples of static friction in real life.
