Friction plays a big role in rolling sports such as tenpin bowling and curling. In tenpin, the friction resistance on the ball makes it slow down and also enables the spin on the ball to make it roll in an arc. The mass and the surface composition of the ball and the amount of oil on the lane will affect the magnitude of … See more When a force is applied to an object, the resistive force of friction acts in the opposite direction, parallel to the surfaces. The standard friction equation for determining the resistive force of friction when trying to slide … See more Air resistance is also a form of friction, as it describes the resistance between the surface of an object or person and the air. Air resistance plays a … See more WebOct 31, 2006 · To study the effects of the normal force, and surface area on the force of friction using a block. To estimate the coefficients of static and kinetic friction. Apparatus: Theory: Limiting static friction : Friction always opposes motion. Larger forces tending to produce the motion, larger friction is. However, it cannot increase indefinitely.
