Projectile
Place a ball within the funnel provided at the top and drop it with the help of the ladder provided
The ball strikes the metal plate fixed at the bottom and bounces.
Note down the distance of the first leap of the ball bounced from the metal base provided
and the angle of the metal plate’s position with the help of the protractor.
Now change the angle of the metal plate and again release the ball from top.
Note down the distance of first leap of the ball. Continue the same procedure
for many angle positions till you reach maximum distance and note down corresponding angle of
the plate. We can find that only at 45° of the plate, the ball covers maximum distance at the first leap.
As per the law of projectile a thrown object can obtain a maximum distance only when it is thrown
initially at an angle of 45°. This phenomenon is used in canyons and rifles to achieve maximum distance.
