Time-of-Flight Accessory (ME-6810): The Timer-of-Flight Accessory facilitates the
accurate measurement of the flight time of a ball launched by a PASCO projectile
launcher. See page 33 (
Time of Flight and Initial Velocity and Figure 9.1) for details of
the setup.
Free Fall Adapter (ME-9207B): The Free Fall Adapter facilitates easy and accurate
measurements of the acceleration of gravity. It comes with everything you need,
including two steel balls (of different size and mass), a release mechanism, and a receptor
pad. The release mechanism and the receptor pad automatically trigger the Smart Timer,
so you get more accurate measurements of the free fall time of the steel ball. See page 34
(
Determining the acceleration due to gravity (g) with the Free Fall Adapter and Figure
10.1) for details of the setup.
Laser Switch (ME-9259A): This highly collimated photodetector is identical to a
photogate, except that a laser (available separately) is used as the light source. With the
Laser Switch, the motion of objects that are too big to fit through a standard photogate
can be measured. Thus, you can measure the period of a bowling ball pendulum or the
velocity of a car, for example.
G-M Tube/Power Supply (SN-7927): The G-M Tube Power Supply is a Geiger-Muller
Probe that senses beta, gamma, and alpha radiation. See page 34 ( Counting radiation
with the G-M Tube/Power Supply and Figure 11.1) for details of the setup.
