About This Chapter
Overview of Gravity - Chapter Summary
Check out this series of physics lessons to boost your understanding of fundamental gravity concepts. Our instructors can help you properly use gravity formulas, solve free fall problems and understand how gravity relates to weight and mass. The chapter includes interactive lesson quizzes, as well as a chapter exam to help you remember key concepts. For your convenience, we've made the chapter available 24/7 and accessible via a desktop, laptop, mobile device or tablet. When you're finished, you'll be able to:
- Use the acceleration of gravity formula
- Explain Newton's laws in terms of gravity, mass and weight
- Calculate acceleration due to gravity
- Solve free fall physics problems
- Show acceleration by graphing free fall motion
- Define and calculate the center of mass
- Use gravity formulas correctly
1. The Acceleration of Gravity: Definition & Formula
In this lesson, we will introduce the acceleration due to gravity. Objects in free fall are one of the few real world examples of straight line motion with constant acceleration, so they are commonly used when learning kinematics.
2. 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.
3. Calculating Acceleration Due to Gravity: Formula & Concept
You have no doubt seen gravity work in your life. After all, it is the force that keeps your feet on the ground! This lesson explores the acceleration a body experiences due to gravity and provides details of the mechanics behind it.
4. Free Fall Physics Practice Problems
In this lesson, we will dive into doing calculations involving free falling objects. We will begin with a few helpful tips to get started before working through a couple of example problems.
5. Graphing Free Fall Motion: Showing Acceleration
Kinematics topics are great for using x, y scatter graphs to visualize motion. In this lesson, we will examine the basic shapes of two different types of graphs of an object in free fall.
6. Calculating Center of Mass: Definition, Equation & Example
What is the center of mass and how is it calculated? Is it the same as the centroid or center of gravity? Learn how to find the center of mass of objects in one-, two-, even three-dimensional space!
7. Practice Applying Gravity Formulas
In this lesson the reader will be introduced to the force of gravity and the formulas used for calculating the force of gravity. This lesson will use real-world examples about how we can use gravity formulas to calculate for unknown forces and variables.
