Test your knowledge with a 30-question chapter practice test
Force: Definition and Types

1. Force: Definition and Types

A force is the push and pull objects exert on each other. Discover types, both contact and non-contact forces, through examples including different measures used to calculate them.

Forces: Balanced and Unbalanced

2. Forces: Balanced and Unbalanced

Forces, the push-pull interaction of objects, are often balanced in their size and opposed in direction--but not always! Learn examples of both balanced, and unbalanced forces, and the expected physics results from an encounter.

Free-Body Diagrams

3. Free-Body Diagrams

Forces are represented in free-body vector diagrams. Understand forces and vectors, define free-body diagrams, and explore examples of free-body diagrams and how they work.

Determining the Individual Forces Acting Upon an Object

4. Determining the Individual Forces Acting Upon an Object

The individual forces that act upon an object are gravity, normal force, friction, air resistance, applied force, tension, spring force, electric force, and magnetic force. Explore each of these types of forces and analyze them through free-body diagrams.

Momentum and Impulse: Definition, Theorem and Examples

5. Momentum and Impulse: Definition, Theorem and Examples

Impulse is directly related to the change in momentum of an object. Learn more about the definition and examples of momentum and impulse, as well as how impulse affects momentum, explore the impulse-momentum theorem, and understand how changing time and force affects the relation.

Conservation of Linear Momentum: Formula and Examples

6. Conservation of Linear Momentum: Formula and Examples

Conservation of linear momentum explains that the momentum of a system will remain the same unless an outside force is applied. Using examples, learn the formula comprising Newton's third law of motion, the relationship between momentum and external forces, and how momentum is conserved in a system.

Elastic and Inelastic Collisions: Difference and Principles

7. Elastic and Inelastic Collisions: Difference and Principles

Elastic and inelastic are the two types of collisions that follow the law of conservation of momentum. Learn about the principles of collisions/momentum and the difference between elastic and inelastic collisions.

Equilibrium: Translational & Rotational

8. Equilibrium: Translational & Rotational

Equilibrium is the state of being balanced physically, and it is an important factor for being in motion. Explore the relationship between motion and equilibrium, focusing on the two types: translational and rotational.

Torque in Physics: Equation, Examples & Problems

9. Torque in Physics: Equation, Examples & Problems

Torque in physics is a force that twists and causes rotation. Explore torque, an equation to calculate torque in simple situations, and an example problem of how to use the equation.

Torque: Concept, Equation & Example

10. Torque: Concept, Equation & Example

Torque refers to the rotational force acting on an object when applied offline from its center of mass. Explore the definition and concept of torque, and learn to apply the torque equation through example calculations.
