Apparatus Falling Bodies (Projectile) (Product Code: SLE/PHY/10) is a spring-release demonstration block used to show that the horizontal and vertical motions of a projectile are independent in school and college physics labs. One press of the trigger catch drops one steel ball straight down and projects a second sideways, and both strike the floor at the same instant. This compact projectile motion kit for school classrooms is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Many students expect a ball fired sideways to stay in the air longer than one that is simply let go. This apparatus tests that idea directly: set the block at the edge of a level bench, place the two steel balls in position and release the trigger catch. The launching bar swings, one ball falls straight down while the other flies out horizontally, and the class hears a single sound as both land together.
The lesson is that gravity gives both balls the same downward acceleration whatever their sideways speed, so the horizontal motion does not change the time of fall. Run it over a hard floor so the landings are easy to hear, keep the landing zone clear, and return the balls to the recess in the block after use. It fits naturally into mechanics lab equipment for secondary and senior-secondary projectile lessons.
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this falling bodies apparatus. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct rather than through a trading middleman. Schools, colleges, laboratory dealers and importers deal with the maker itself, so questions about spare steel balls or repeat orders reach the people who build the unit — just ask us. More about the company is on the ScienceLab company profile.

What does the Apparatus Falling Bodies (Projectile) demonstrate?
The Apparatus Falling Bodies (Projectile) demonstrates that horizontal and vertical motions are independent. When the trigger catch is released, one steel ball drops vertically while the other is projected horizontally, and both hit the floor at the same time because gravity accelerates each of them downward equally.
What comes with the falling bodies projectile apparatus?
The falling bodies projectile apparatus consists of a wooden block of about 190 x 58 x 30 mm carrying a pivoted L-section, spring-loaded metal launching bar with a trigger catch. It is supplied with 2 steel balls, which are kept in a storage recess in the block.
How should the projectile apparatus be set up in class?
Place the Apparatus Falling Bodies (Projectile) at the edge of a level bench above a hard floor, so the two landings can be heard clearly. Keep students out of the landing area, release the trigger catch, and then return both steel balls to the recess in the block.
Who manufactures the Apparatus Falling Bodies (Projectile)?
The Apparatus Falling Bodies (Projectile) is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India. Buyers order it direct from the manufacturer instead of through a reseller.
What should a quotation request for SLE/PHY/10 include?
A quotation request for the Apparatus Falling Bodies (Projectile), code SLE/PHY/10, should state the quantity, the delivery city or country, and any other physics items you want on the same order. Send these details through the ScienceLab contact page for a quote from the manufacturer.
Can schools and dealers order the falling bodies apparatus in bulk?
Yes. ScienceLab supplies the Apparatus Falling Bodies (Projectile) in class-set and bulk quantities to schools, colleges, dealers and importers in India and international markets. Share the quantity and destination through the contact page so the order and shipment can be planned.
To order the Apparatus Falling Bodies (Projectile), send your quantity and delivery location through the ScienceLab contact page, or add the item to the enquiry cart together with the rest of your physics list. The quotation comes straight from the manufacturer.
