Force: Definition and Types

1. 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.

The Normal Force: Definition and Examples

2. The Normal Force: Definition and Examples

The normal force is also called the contact force because it only exists when objects are touching. In this lesson, we will investigate what the normal force is and how to calculate it on flat and inclined surfaces.

Static Friction: Definition, Formula & Examples

3. 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.

Sliding Friction: Definition, Formula & Examples

4. Sliding Friction: Definition, Formula & Examples

Sliding friction is different than static friction for most material combinations. Find out how it differs, when to apply this concept, and how to calculate the forces involved in this lesson.

Hooke's Law & the Spring Constant: Definition & Equation

5. Hooke's Law & the Spring Constant: Definition & Equation

After watching this video, you will be able to explain what Hooke's Law is and use the equation for Hooke's Law to solve problems. A short quiz will follow.

Practice Applying Force & Acceleration Formulas

6. Practice Applying Force & Acceleration Formulas

In this lesson, we will introduce force and acceleration formulas using Newton's Force Laws and demonstrate kinematic equations, including examples, to solve real-world problems.
