Useful for study and demonstration of the concept of motion on an inclined surface and its relation to the friction. A pair of polished wooden boards attached together at each end are hinged at one end to a metal baseboard below it so that the wooden boards can be moved to form an inclined surface. One side of the board has a linear scale graduated ellery 5cm to measure linear distance along its length, while an adjustable and removable angle measurer or arc scale, attached to the metal base board on the same side and graduated 0-45?x 1 ? measures the angle of inclination. The angle measurer also has linear scale graduated in centimeters to measure the vertical height of inclined surface at a point. A plastic pulley attached to the end of inclined boards supports masses suspended from thread, the other end of thread being connected to the objects moving on inclined surface

BALLISTICS CAR (0144)
Useful for studying the v e c tor quantities associated with the projectile motion and demonstrates that the horizontal component of velocity of the object projected from another object moving horizontally is same as that of the horizontally moving object and is independent of the vertical component of velocity of projected object at any instant. Comprises a car made of heavy gauge aluminium with 4 low friction bearing wheels. The car has a heavy cylindrical barrel mounted vertically at its top which houses a spring loaded piston for shooting the ball vertically. The two locking position of the spring loaded piston arrangement provides two different but reproducible vertical projection velocities. Includes a steel sphere and a lock pin with cord. With the car moving with some horizontal velocity, if the steel sphere is projected upward, its trajectory will appear to be parabolic when viewed by a stationary observer and the sphere will return back to into the vertical barrel, irrespective of the velocity of projection or velocity of the moving
