Ch 36: Equilibrium and Momentum for the MCAT: Tutoring Solution

About This Chapter

The Equilibrium and Momentum chapter of this MCAT Prep Tutoring Solution is a flexible and affordable path to learning about the effect of force. These simple and fun video lessons are each about five minutes long and they teach all of the equilibrium and momentum topics required in a typical MCAT prep course.

How it works:

  • Begin your assignment or other MCAT test-prep work.
  • Identify the equilibrium and momentum concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our MCAT Tutoring Solution will benefit any student who is trying to learn about equilibrium and momentum and prepare for the exam. This resource can help students including those who:

  • Struggle with understanding the different types of force, collisions, rotational dynamics, torque or any other equilibrium and momentum topic
  • Have limited time for studying
  • Want a cost effective way to supplement their MCAT preparation
  • Prefer learning science visually
  • Find themselves struggling with equilibrium and momentum
  • Cope with ADD or ADHD
  • Want to get ahead in preparing for the MCAT
  • Need access to MCAT preparation materials

Why it works:

  • Engaging Tutors: We make preparing for the MCAT exam 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 MCAT prep tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Review equilibrium and momentum on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

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.

Equilibrium: Translational & Rotational

2. Equilibrium: Translational & Rotational

Learn about the requirements for an object to be under translational or rotational equilibrium. Then work through a couple example problems that show how we can use translational and rotational equilibrium to find the forces acting on an object.

Forces: Balanced and Unbalanced

3. 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.

Free-Body Diagrams

4. Free-Body Diagrams

Forces that act on an object can be drawn through special vector diagrams called free-body diagrams. In this video lesson you'll identify how to correctly represent forces in a free-body diagram through vector arrows and force labels.

Determining the Individual Forces Acting Upon an Object

5. Determining the Individual Forces Acting Upon an Object

Objects constantly have forces acting on them whether they are moving or at rest. In this video lesson, you'll understand how to identify the individual forces acting on an object by reviewing the different types of forces and the use of free-body diagrams.

Torque in Physics: Equation, Examples & Problems

6. Torque in Physics: Equation, Examples & Problems

After watching this video, you will be able to explain what torque is and use an equation to calculate torque in simple situations. A short quiz will follow.

Torque: Concept, Equation & Example

7. Torque: Concept, Equation & Example

After watching this lesson, you will be able to explain what torque is conceptually and mathematically and use both the equation and Newton's First Law for rotation to solve problems involving torque. A short quiz will follow.

Momentum and Impulse: Definition, Theorem and Examples

8. Momentum and Impulse: Definition, Theorem and Examples

To understand how a change in momentum affects an object, we look to impulse. In this lesson, you'll understand how impulse describes an object's change in momentum, as well as how changing the force or time of the impulse can have very different outcomes.

Conservation of Linear Momentum: Formula and Examples

9. Conservation of Linear Momentum: Formula and Examples

The law of conservation of momentum tells us that the amount of momentum for a system doesn't change. In this lesson, we'll explore how that can be true even when the momenta of the individual components does change.

Elastic and Inelastic Collisions: Difference and Principles

10. Elastic and Inelastic Collisions: Difference and Principles

When objects come in contact with each other, a collision occurs. In this lesson, you'll learn about the two types of collisions as well as how momentum is conserved in each.
