There are Seven application of centrifugal force.
i. When a car in motion takes a sudden turn towards left, passengers in car experience an outward push to the right. This is due to centrifugal force acting on the passengers.
ii. A bucket full of water is rotated in a vertical circle at a particular speed, so that water does not fall. This is because, weight of water is balanced by centrifugal force acting on it.
iii. The children sitting in merry-go-round experience an outward pull as merry-goround rotates about vertical axis. This is due to centrifugal force acting on the children.
iv. A coin kept slightly away from the axis of rotation of turn table moves away from axis of rotation as the speed of rotation of turn table increases. This is due to centrifugal force acting on coin.
v. The bulging of earth at equator and flattening at the poles is due to centrifugal force acting on it.
vi. Drier in washing machine consists of a cylindrical vessel with perforated walls. As the cylindrical vessel is rotated fast, centrifugal force acts on wet clothes. This centrifugal force, forces out water through perforations thereby drying wet cloths quickly.
vii. A centrifuge works on principle of centrifugal force. In centrifuge, a test tube containing liquid along with suspended particles is whirled in a horizontal circle. Denser particles are acted upon by centrifugal force, hence they get accumulated at bottom which is on outside while rotating
