After watching countless hours Olympic Game coverage, Trace became curious about the actual physics behind curling. Curiosity got the best of him, and he decided to learn about it first hand by actually learning how to play from the professionals themselves! (04:08)

In order to use Newton’s Second Law, you need to correctly draw the Free Body Diagram. This problem explains a common mistake students make involving the force applied. We also review how to find acceleration on a velocity as a function of time graph. (05:58)

Volcanoes 101
From NationalGeographicVideo, produced by National Geographic

Today we know volcanoes are openings or vents to the interior of the planet. About 1,500 volcanoes around the world are considered active, about 90% rest in the Ring of Fire, a band circling the Pacific Ocean. While the Earth’s surface looks peaceful the crust is made up of slabs of rock that constantly shift, where the plates interact, volcanoes often form. Friction from shifting plates melts the Earth’s crust, causing rock beneath the crust to liquefy. This magma then becomes a volcano by erupting through rifts in the plates. Not all lava is the same. Volcanoes can be deadly, but it can also be good, it created 80% of Earth’s surface and the air we breathe, rich soil for farming, and some countries harness the heat to create geothermal energy. Video is very interesting and good quality. Good for elementary grade and middle school students.

A rubber band twisted around the axle of a plastic car provides the force that moves the car forward. In this workshop, fifth-grade students continue their exploration of force and motion by recording and comparing the distance a vehicle travels under various conditions. Students predict the distance the car will travel by counting the number of twists in the rubber band, and observe the car’s speed as it rolls across the floor. When the force of the rubber band stops acting, the force of friction slows the car to a stop.

This video discusses the history behind the wheel and how it was changed to make a gear. The video also discusses gears, gear speed and direction, circumference, diameter, radius, combining different size gears, driver gear vs driven gear, gear trains, gear ratio, gear friction, gear pairs (compound gears), lever arm, torque, and rim force.

In this slow motion video for IPS Schools by Clayborn a ball is released on an inclined plane and accelerates due to the force of gravity. At the bottom of the first inclined plane to the beginning of the second inclined plane the ball stops its positive acceleration by nearly maintaining its horizontal speed. On the second ramp the ball accelerates backwards down the slope, or loses speed to a point where it momentarily comes to rest. Therefore this video demonstrates POSITIVE ACCELERATION, ZERO ACCELERATION, AND NEGATIVE ACCELERATION or acceleration in the opposite direction. This video ignores friction and wind resistance and was intended for basic illustration of acceleration. (05:02)

This professionally-made music video from They Might Be Giants explains that a shooting star is actually is a meteor in the sky. Cartoons are simple and cute while the tune and lyrics are catchy and easy to remember. Some lyrics include "A shooting star is not a star, is not a star at all. A shooting star is a meteor that's heading for a fall. A shooting star is not a star. Why does it shine so bright? The friction as it falls through air produces heat and light. A shooting star or meteor, whichever name you like. The minute it comes down to Earth it's called a meteorite." (01:32)

Ask the Astrophysicist, Neil deGrasse Tyson, goes to the park to see if anyone has any questions. A boy in the park asks, “How fast does meteorite moves in space?” He explains that meteor moves through space and if you find it on the ground then it is a meteorite. Sometimes the speed is 10-15 miles per second. He then shows the children friction and explains how the atmosphere protects us from meteorites. Video is great quality and sound is also. Good video for younger student, gives a good and simple answer to the question. Video is good for elementary level students. (03:04)

This NASA video segment explores how Newton's laws apply to the takeoff of an airplane. Viewers watch an instructor and engineer at NASA's National Test Pilot School and learn that there are four opposing forces on an airplane, that takeoff is the point at which the lift just starts to offset the weight, and that the distance needed for takeoff can be calculated using an equation derived from Newton's second law. The video clip also discusses the extra drag force created by the rolling friction of the airplane's wheels.

In this interactive resource adapted from the University of Colorado's Physics Education Technology project, hang various masses from different springs and observe how kinetic, gravitational potential, elastic potential, and thermal energy are related. A bar graph illustrates the conservation of energy by showing how the total energy of the system remains the same while the levels for the different forms of energy vary. Options allow you to choose the stiffness and amount of friction of a spring and see how different amounts of gravity affect the system.
