Ch 15: Equilibrium and Momentum for the MCAT: Help and Review

About This Chapter

The Equilibrium and Momentum chapter of this MCAT Prep Help and Review course is the simplest way to master equilibrium and momentum. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of equilibrium and momentum for the MCAT.

Who's it for?

Anyone who needs help learning or mastering MCAT material will benefit from taking this course. There is no faster or easier way to prepare for the MCAT. Among those who would benefit are:

  • Students who have fallen behind in understanding the relationship between equilibrium, momentum and force
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about equilibrium and momentum for the MCAT
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.

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.

Forces: Balanced and Unbalanced

2. 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

3. 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

4. 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.

Momentum and Impulse: Definition, Theorem and Examples

5. 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

6. 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

7. 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.

Equilibrium: Translational & Rotational

8. 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.

Torque in Physics: Equation, Examples & Problems

9. 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

10. 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.
