How does the direction of acceleration compare with the direction of net force that produces it?

When multiple forces are applied to an object, they may be either concurrent or parallel. In this lesson, learn how to identify concurrent and parallel forces and how to find the resultant of a concurrent or parallel force system.

This lesson is about Samuel de Champlain, an explorer from France who settled part of Canada. Find out about his life, his travels, and his maps, which were some of the first of this part of the world.

In this lesson, you'll learn about linear momentum, impulse, and energy conservation. These are all important components of collisions, which can be large, small, and everything in between!

After watching this video, you will be able to explain how a spring-block oscillator is an example of simple harmonic motion. You will also be able to use an equation for a spring-block oscillator that relates the frequency and mass of the block.

In this lesson, we explore the Peace of Utrecht that ended the War of the Spanish Succession and the widespread ramifications it had for the emerging and declining powers of Western Europe.

When it comes to building bridges, there are many types to choose from. Truss bridges have been a top choice for hundreds of years. Come and learn about what these bridges are like, their pros and cons, and examples in the real world.

Samuel de Champlain was a mariner, cartographer, explorer, adventurer, and governor in New France. He is best known as the founder of Quebec, Canada, and is called the 'Father of New France.'

It's very often necessary to describe the location of a point in space. Position vectors do this in a very precise way. In this lesson we look at the mathematical formula for position vectors and then you'll be able to test your knowledge with a quiz.

Canada is divided into six physical regions. Come and learn about each of these regions, their defining characteristics, and some fun facts about what makes each region special.

Learn how European explorers and colonists affected First Nations communities in Canada. In addition to getting involved in wars between the French and the British, the First Nations suffered from the introduction of European diseases, weapons, and forced assimilation programs.

In this lesson, we are going to learn about two categories of structure; one can be analyzed using statics, and the other cannot be analyzed using statics only. We are going to learn about statically determinate structures, and we will give equations and examples for them.

Vectors are entities that have two pieces of information associated with them, magnitude and direction. In this lesson, we will practice adding and subtracting vectors both graphically and algebraically. To do this we will break vectors down into their components.

In this lesson, we review how biomechanics and kinesiology relate to both motor skills and movement patterns. We also discuss some of the basic principles of each and how they relate to human movement, the brain, muscles, and the body.

This lesson is about Augustus, the first emperor of Rome. In this lesson we follow Augustus's meteoric rise to power, the collapse of the Roman Republic, and the rise of the Roman Empire.

Stress is one of the most common causes of structural failure. This lesson contains the definitions of the major types of stress, what causes them, and the equations needed to compute an object's stress.

You experience friction all the time, and you should be glad you do! Friction helps keep stationary objects in place as well as slow moving objects down as they slide across a surface. This lesson identifies what friction is and explains the two ways we find this force on earth.
