Answer:
Explanation:
Calculate the force of friction using the formula:
F = μN
Where N is the normal force and μ is the friction coefficient for your materials and whether they’re stationary or moving. The normal force is equal to the weight of the object, so this can also be written:
F = μmg
Where m is the mass of the object and g is the acceleration due to gravity. The friction acts to oppose the motion of the object.
