Newton's Laws of Motion illustrated with 3D AnimationsGrade: 6  12 Learn about Isaac Newton's three laws of motion with this animated lesson. 4:30 

Newton's Laws of MotionGrade: 6  12 An introduction to Newton's Laws of Motion. 4:20 

Newton's Three Laws of MotionGrade: 6  12 Lesson on Newton's three laws of motion. It describes the first law that relates to inertia, the second law that relates to mass and acceleration, and the third law that allows a rocket to launch. 7:20 

Demonstration of Newton's First Law of MotionGrade: 6  12 Newton's first law of motion is pretty important if you are trying to get a rocket up into space. 2:40 

Demonstration of Newton's Second Law of MotionGrade: 6  12 The video demonstrates Newton's Second Law of Motion with high powered air cannons. 3:10 

Demonstration of Newton's Third Law of MotionGrade: 6  12 A fun demonstration of Newton's third law of motion. How do we launch rockets and shuttles into space? Of course, with Sir Isaac Newton and his laws of motion. 2:50 

What is Friction?Grade: 6  12 Lesson on force of friction. It can be classified as static or kinetic force of friction depending on whether the body is at rest or in motion. It explains that the frictional force is directly proportional to the weight of the body. 7:00 

Circular Motion ExplainedGrade: 6  12 Explore the science of spinning, circular motion and the centripetal force. Find the connection between merrygorounds and artificial gravity. 4:30 

Centripetal Force ExplainedGrade: 6  12 A lesson on centripetal force. The video demonstrates inertia and centripetal force (not centrifugal) with science experiments. 3:00 

Angular Momentum ExplainedGrade: 6  12 Find out about the law of conservation of angular momentum. See it in action when ice skaters spin faster by hugging themselves tight. Watch a few more angular momentum examples. 5:00 

Lesson on InertiaGrade: 6  12 Introduction to the concept of inertia, the first law of physics  Things like to keep on doing what they're already doing. 4:50 

Lesson on SpeedGrade: 6  12 The video introduces the concept of speed to the inertiamass relationship. It explains that force varies with mass and rate of change of speed. 4:50 

Lesson on Acceleration, part 1Grade: 6  12 Learn how Force equals Mass x Acceleration. The lesson illustrates this important rule of physics with the examples of a bicycle and a baseball player. 4:50 

Lesson on Acceleration, part 2Grade: 6  12 Learn how acceleration works, and how to calculate it with the help of an animated locomotive. It stresses the importance of reasonable units, and that acceleration is measured in m/s². 4:50 

Lesson on MassGrade: 6  12 Building on the concept of inertia, this lesson introduces the concept of mass, tells how it's measured, and shows how it differs from size. It explains that inertia increases with mass. 4:50 

Lesson on GravityGrade: 6  12 Learn about the force of gravity with the help of Isaac Newton's celebrated falling apple. It also explains the unit with which the force of gravity is measured. 4:50 

Forces  Mass and Weight ExplainedGrade: 6  12 Do you know the difference between Mass and Weight? Get the answer in this physics lesson. 3:50 

Newton's First Law of MotionGrade: 6  12 A lesson on Newton's First Law (Galileo's Law of Inertia). 9:30 

Newton's Second Law of MotionGrade: 6  12 A lesson on Newton's Second Law of Motion: F=ma. 7:15 

Newton's Third Law of MotionGrade: 6  12 A lesson on Newton's Third Law: Every action has an equal and opposite reaction. 8:00
