Newton's Three Laws of Motion
Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.

Newtons 2nd Law of Motion | Force, Mass, Acceleration
Newton's 2nd Law of Motion tells us that if a net force is applied to an object then that object will accelerate in the direction of the net force. This means that is a force a force is applied to an object, it will either speed up, slow...

The ONE thing your teacher is NOT telling you that will simply forces!
Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...

Newtons 3rd Law of Motion - Action and Reaction
Newton's 3rd Law of Motion tells us that for every action, there is an equal and opposite reaction. In this video students will learn about Newton's 3rd Law of Motion and be able to give examples of this law in the world around them and...

How to Calculate Force - Newton's 2nd Law of Motion
Newton's 2nd Law tells explains how force can affect the acceleration of an object. The more force you apply to an object, the more it will accelerate. Also, the more mass an object has, the more force that is needed to cause the object...

How to Calculate Momentum - Newton's 3rd Law of Motion - p=mv
Newton's 3rd Law of Motion states that for every action there is an equal and opposite reaction. The formula associated with Newton's 3rd Law is p=mv where p is momentum, m is mass and v is velocity. In this video, we will cover how to...

Separating Notebooks
We interleave the pages of notebooks to see how hard it is to pull them apart. As the amount of interleaving increases, we see that the force required to separate them also increases. This is because the friction between the notebooks is...
