Question

If normal force is doubled, what happens to friction? Discuss.​

Answer 1

Answer:

$\huge{\underline{\bold{\orange{AnswEr}}}}$

Explanation:

If normal force is doubled the coefficient of the kinematic friction of a body also doubled up to the motion about to started. But once after the movement is started and continues to move, the kinetic friction decreases as force doubled

Answer 2

Answer:

Not possible

Explanation:

Normal Force will double only when weight is doubled  As N = W

W = mg

mass cannot be doubled , acceleration  due to gravity is constant .
