Gyroscopes Made Easy

Gyroscopes Made Easy

MIT Department of Physics Technical Services Group

Added over 2 years ago | 00:29:09 | 5201 views

The motion of a gyroscope in response to an applied force is analyzed.  TSG's gimbaled gyroscope is used to demonstrate.

Steel Ball Dropped in a Viscous Fluid

Steel Ball Dropped in a Viscous Fluid

MIT Department of Physics Technical Services Group

Added over 3 years ago | 00:02:03 | 11393 views

Five steel balls of different sizes are dropped into corn syrup. The balls reach a constant velocity shortly after entering the fluid. The velocity is constrained due to the drag balancing the force of gravity in the fluid. This demon...

Bell Labs Wave Machine: Mismatched Impedance

Bell Labs Wave Machine: Mismatched ...

MIT Department of Physics Technical Services Group

Added almost 4 years ago | 00:01:24 | 12251 views

Two segments of the Bell Labs apparatus are connected. The segments have different impedance. When a pulse travels from high impedance to low impedance, it is reflected with positive polarity and transmitted with positive polarity. Wh...

Bell Labs Wave Machine: Reflection

Bell Labs Wave Machine: Reflection

MIT Department of Physics Technical Services Group

Added almost 4 years ago | 00:01:00 | 15573 views

Pulses are created on the Bell Labs apparatus and reflections from the opposite end are observed. Initially, the ends of the apparatus are left open and the reflections have positive polarity. When one end is fixed, reflections have ne...

Pulling a Cloth From Under a Beaker

Pulling a Cloth From Under a Beaker

MIT Department of Physics Technical Services Group

Added almost 4 years ago | 00:00:50 | 15879 views

A beaker is placed on top of a cloth, on top of a stool. The cloth is pulled quickly from underneath the beaker, while the beaker remains stationary. The impulse of the net force is made very small by reducing the time over which the c...

A ball rolls down an inclined track and around a vertical circle. All of the ball's initial potential energy is converted into three forms of energy when it reaches the top of the loop: potential energy corresponding to the height of th...

Plate Sliding Under a Soda Can

Plate Sliding Under a Soda Can

MIT Department of Physics Technical Services Group

Added almost 4 years ago | 00:00:50 | 16173 views

A can is placed on top of a metal sheet on a stool. A broom hits the sheet causing it to fly from underneath the can, while the can remains stationary. The impulse of the net force is made very small by reducing the time over which the...

Wooden Block Between Two Strings

Wooden Block Between Two Strings

MIT Department of Physics Technical Services Group

A block of wood is attached vertically between two strings. When the bottom string is pulled slowly, the top string breaks. When the bottom string is pulled quickly, it itself breaks.

Spring Paradox

Spring Paradox

MIT Department of Physics Technical Services Group

Added 4 years ago | 00:01:01 | 17591 views

A mass hangs from two identical springs. First, the springs are attached in series by a short string between them. The springs are also connected in parallel by two peripheral strings that are initially slack. The center string is cut...

Double Cone and Plane

Double Cone and Plane

MIT Department of Physics Technical Services Group

Added 4 years ago | 00:01:11 | 19920 views

A double cone is placed on the bars of an inclined plane. Instead of rolling down the plane the cone rolls up. Although the plane slants upward, the bars diverge so that the rotational axis of the cone, which passes through the center of...

Feather and Coin in a Vacuum

Feather and Coin in a Vacuum

MIT Department of Physics Technical Services Group

Added 4 years ago | 00:02:08 | 20917 views

The free fall of a coin and feather are compared, first in a tube full of air and then in a vacuum. With air resistance, the feathers fall more slowly. In a vacuum, the objects fall at the same rate independent of their respective masses.

Interrupted Pendulum

Interrupted Pendulum

MIT Department of Physics Technical Services Group

Added 4 years ago | 00:01:40 | 14888 views

A pendulum swings from a support post and another post is added to interrupt its swing. We desire to know the maximum height at which the pendulum will perform a full loop around the post. The pendulum requires both potential and kinet...
