What is Position in Physics? - Definition & Examples

1. What is Position in Physics? - Definition & Examples

After watching this video, you will be able to explain what position is, why it is a vector, and interpret position-time graphs. A short quiz will follow.

Speed and Velocity: Concepts and Formulas

2. 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.

Distance, Time & Average Speed: Practice Problems

3. Distance, Time & Average Speed: Practice Problems

After watching this video, you will be able to explain what distance is, explain how it relates to change in position, and calculate the average speed in various situations. A short quiz will follow.

Force: Definition and Types

4. 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.

Graphing Position & Speed vs Time: Practice Problems

5. Graphing Position & Speed vs Time: Practice Problems

After watching this video, you should be able to explain what position and speed are. You should also be able to plot position vs. time and speed vs. time graphs. A short quiz will follow.

Objects with Two or More Forces: Finding the Total Force Result

6. Objects with Two or More Forces: Finding the Total Force Result

After watching this video, you will be able to explain what a force is and how it relates to motion, and find the total force result in a variety of force situations. A short quiz will follow.

Newton's First Law of Motion: Examples of the Effect of Force on Motion

7. 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.

Newton's Second Law of Motion: The Relationship Between Force and Acceleration

8. 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.

Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

9. 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.

Forces: Balanced and Unbalanced

10. 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.

Newton's Laws and Weight, Mass & Gravity

11. 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.

Gravity in the Solar System: Shaping Planets & Stars

12. Gravity in the Solar System: Shaping Planets & Stars

After watching this video, you will be able to explain what gravity is, and the role it plays in forming the shapes of planets and stars. A short quiz will follow.
