‘Gravity’ By Free Fall Apparatus
Consists of an electromagnet housed in a plastic moulded case with connections for an external timer, with a heavy steel sphere, and a platform unit.
For determination of 'g' (the gravitational acceleration) by free fall method.
The apparatus consists of an electromagnet which is housed in a plastic moulded case with 4 mm socket connections provided to energize the magnet and another pair of sockets for connection to a timer in use.
To perform the experiment, an electromagnet is energized and a metal sphere is attached.
As soon as the power to the electromagnet is switched off the sphere falls and the unit activates the timer.
When the sphere hits the platform, which is connected to a micro switch, the timer stops and the time of fall can be determined.
For use with compatible timer (product code LBTM).
Unit conveniently attaches to all commonly used stands (stand not supplied, see Stand & Rod Assembly - Value Pack STD-RD).
Baby Weighing Balance
A single beam scale, robust steel body with epoxy powder coated parts.
The beam carries a sliding weight to indicate the weight from 0 to 5kg in divisions of 20 grams each.
One hanger and one slotted mass is provided to increase the capacity of the balance.
When only the hanger is suspended from the end of the beam the capacity increases to 10 kg and the reading starts from 5 kg onwards on the scale up to 10 kg.
On adding the slotted mass on to the hanger the capacity increases to 15 kg and the reading starts from 10 kg onwards on the scale up to 15 kg.
The tray is detachable and can be easily replaced in position by sliding on to fixed plate.
Second scale is provided which reads 0 to 1 kg in division of 10 gms.
Making the total capacity of balance 16 kg in to 10 gms.
