Nasa: Introduction to Newton's Three Laws: Lesson 1
View this video that relates Newton's Law of Motion to the operation on airplanes. Learn how mass of a person can be calculated by dividing the weight of the person to the force of gravity. [12:08]
Khan Academy
Khan Academy: Normal Force: Normal Force and Contact Force
A discussion of the force that keeps a block of ice from falling towards the center of the Earth. The example problem has two 5-kg blocks of ice on the surface of a frozen lake, one stationary and one moving at a constant velocity. [7:18]
Khan Academy
Khan Academy: Tension: Tension in a Accelerating System and Pie in the Face
The second part to a complicated problem. We figure out the tension in the wire connecting two masses. Then we figure our how much we need to accelerate a pie for it to safely reach a man's face. [9:28]
Khan Academy
Khan Academy: Inclined Planes and Friction: Inclined Plane Force Components
An analysis of the components of the force due to gravity that are parallel and perpendicular to the surface of an inclined plane. [12:43]
