Galilean relativity Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12575
Quick Answer: The Galilean Relativity apparatus is a 1200 mm aluminium track with a motor-driven cart carrying a spring-loaded vertical launcher, used to compare a projectile’s path seen from the moving cart and from the bench. The cart runs at a steady 0.1 m/s to 1.0 m/s.

About This Product
With the cart still, a ball fired straight up lands back in the launcher. With the cart moving at a constant speed, the ball still rises and falls straight back into it as seen from the cart, while students at the bench see a parabola, showing that the laws of motion and the acceleration due to gravity are the same in both inertial frames.
Frequently Asked Questions
Where does the ball land when the cart of the Galilean Relativity apparatus is moving?
Back in the launcher cup, because the ball keeps the cart’s horizontal velocity; from the bench its path is a parabola.
