Who's it for?
This chapter of our middle school physical science tutoring solution will benefit any student who is trying to learn motion and forces and earn better grades. This resource can help students including those who:
- Struggle with understanding position in physics, force, Newton's Laws of Motion, the role of gravity in the solar system, or any other motion and forces topic
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their motion and forces unit
- Cope with ADD or ADHD
- Want to get ahead in physical science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning motion and forces simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live physical science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn motion and forces on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Define position in physics.
- Learn the formulas for speed and velocity.
- Solve problems involving distance, time and average speed.
- Graph speed vs. time.
- Identify the different types of forces.
- Find the total force result when an object has two or more forces.
- Examine Newton's first, second and third laws of motion.
- Differentiate between balanced and unbalanced forces.
- Understand the relationships between weight, mass and gravity.
- Explain how gravity helps to shape the planets and stars.
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.
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.
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.
4. 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.
5. 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.
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.
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.
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.
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.
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.
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.
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.
13. Mechanical Advantage: Definition & Formula
Why do people use machines? This lesson introduces and explains the concept of mechanical advantage. It also discusses how to calculate the mechanical advantage of simple machines. A summary and brief quiz is included.
