Friction Questions and Answers | Latest Update | 2024/2025 | Already Passed Define the coefficient of friction. The coefficient of friction is the ratio between the force required to move or keep an object in motion and the normal force exerted on it. What is drag? Drag is the resistance experienced by a solid moving through a liquid or gas. Describe friction. Friction is a force that opposes the movement of objects. What is normal force? Normal force is the perpendicular force that presses two surfaces together. On a flat surface, it counteracts the object's weight with an equal force but in the opposite direction. Explain rolling friction. Rolling friction is the force that resists the motion of an object as it rolls over a surface. 2 What is sliding or kinetic friction? Sliding or kinetic friction is the resistance encountered when an object slides over a surface. Define starting or static friction. Starting or static friction is the force that prevents an object from beginning to move. What is weight? Weight is the force that results from a mass being pulled by gravity. It is calculated using the formula ( F_w = mg ). The resistance force when moving one object against another is known as ________. Friction Friction occurs when _______ interact on
