Kinematics & Newton's Laws of Motion

Rich Eisen runs the 40-yard dash. The former SportsCenter anchor struggles to keep pace with fastest-in-the-draft football player Jacoby Ford and 370-pound nose tackle Terrence "Mount" Cody.

Hammer & Feather Dropped on Moon During the Apollo 15 mission, an astronaut drops a hammer and feather while on the surface of the moon to illustrate that acceleration due to gravity is independent of an object's mass. Without an atmosphere there is no air resistance so the objects are truly in freefall.

Feather & Ball Bearing Dropped in a Vacuum Similar to the hammer and feather experiment from the Apollo 15 moon mission, the demonstration in this video uses a vacuum chamber to get rid of air resistance without hitching a ride with NASA.

Bowling ball and feathers dropped in world's largest vacuum chamber with BBC.

An astronaut plays baseball with himself, Bugs Bunny style. Lots to talk about regarding constant velocity motion and force.

Zero gravity cats, version 1 and version 2. Science can be... odd.

Water balloons popped in a zero gravity environment.

Throwing a rock down a 1500 foot hole. Is the hole really 1500 feet deep?

Quarry jump from "more than 100 ft." Did the maker of the video slow it down?

If you want to know what a "World Record Blob Jump" entails you'll need to watch this video. Great demonstration of projectile motion and conservation of energy.

Here's six different "world record" jumps that demonstrate projectile motion: Travis Pastrana in a car, Team Hot Wheels in a truck, Robbie Maddison jumping a motorcycle for distance and for height, Levi Levallee on a snowmobile, and a dual jump with a motorcycle and a snowmobile (here's the helmetcam view.)

A gymnastics accident. Real or fake?

Ice falling off of a roof forms a nice parabola on the way down.

The view from the bomb bay doors is a good example of projectile motion.

A girl swimming across a river; a great example of vector addition.

Shopping Cart Fail An excellent demonstration of inertia.

Bowling ball from car accident.

Unloading a truck with Newton's 1st Law.

Newton's 3rd Law Demonstration This demonstration of Newton's 3rd Law can be thought of as a low speed gun firing a large bullet, illustrating the concept of "kickback." And here's a collection of people unprepared for the massive kickback of a huge gun--Newton's 3rd Law in action!

DJ's failed stage dive demonstrates Newton's 3rd Law.

Monster Truck Tug-of-War. Find the tension in the tow strap.

Pilot pours a glass of iced tea while doing a barrel-roll without spilling a drop!

Water trapped in a double-paned window of a moving bus.

Talented (crazy?) helicopter pilot takes inertia/momentum into account when delivering Christmas trees. (And the perspective from the helicopter.)

Parkour-style stunt (gif) demonstrates the independence of translational and rotational motion.

Punting a soccer ball from the back of a flatbed truck demonstrates independence of x and y motion.

An astronaut aboard the ISS demonstrates acceleration as the space station does a "reboost" burn.
