Mit Physics Demo -- Strobe Of A Falling Ball

A ball is dropped in front of a meter stick and lit by a strobe light. A long exposure photograph captures the position of the ball at each evenly spaced flash of light. The acceleration of the ball can then be measured from the photo. Note that the frame rate of the video capture (30fps) is quite close to the strobe rate (15Hz). This is why the strobe flashes in the slow motion video don't appear to be exactly evenly ...

Mit Physics Demo -- Speed Of A Bullet

A pair of spinning wheels 1.5 meters apart is placed in the path of a bullet. A bullet is fired with the wheels stationary for reference position, and fired again with the wheels spinning at a known speed. The second wheel will rotate more than the first as the bullet crosses the gap between them. When the angles between the reference holes and the second holes are compared, the speed of the bullet can be determined. The balloon is used to ...

Mit Physics Demo -- Monkey And A Gun

A stuffed monkey is suspended from a rod at one end of a lecture hall by an electromagnet. A golf ball gun aimed directly at the monkey cuts power to the electromagnet when fired. Thus, the monkey begins falling at the same instant the gun fires the golf ball. The projectile and target meet in mid air. Intuitively one might think that the ball will go over the monkey's head due to its fast speed. However, gravity accelerates all objects ...

Mit Physics Demo -- Low Friction Atwood Machine

A string carrying two weights is hung over a low friction bearing mounted pulley. The weights have slightly different masses, causing a uniform acceleration. When the time it takes the weights to move 1 meter is timed, we can calculate the acceleration of the system due to gravity. Because of the low amount of friction in the system, this value is very close to the theoretical value.

Mit Physics Demo -- Centrifugal Versus Centripetal Motion

A wooden ball is attached to the rim of a spinning wheel. The ball is held in place by a string. When the spring is cut, the ball flies in a straight tangent to the wheel. In the camera's frame of reference, the ball constantly accelerates around in a circle due to the centripetal force pulling it inwards. When the string is cut, the acceleration stops, and the ball flies away in a straight tangential line. When the string is ...

Mit Physics Demo -- Bicycle Wheel Gyroscope

A bicycle wheel is suspended from one of end of its axie by a rope, and spun up by hand. The wheel's axle is then placed horizontally and the free end of the axle processes about the supported end. The gyroscope seems to defy gravity because the torque created by the spinning wheel counteracts the torque due to gravity. Gyroscopes have been used through history for varied uses such as stabilizing spacecraft or for guidance systems on ships and missiles. ...
