Question

If mass of an object doubles, the friction force acting on it

Answer 1

If the body is not moving , then static frictional force comes into play .Static friction is a self adjusting force , hence when the applied force is doubled ,then friction becomes double .

But when the object is moving, then kinetic friction comes into play. And when applied force is greater than the frictional force, then friction willn't change according to the applied force.

So we can't say directly that the friction force will get doubled or halved on doubling the force.

here is your answer I hope it's help you

Answer 2

Answer:

double

Explanation:

as we know f = ma

but the frictional force always opposes motion

so

if m becomes 2

then acceleration will be reduced and friction will be increased by 2 times

and acceleration will be reduced to half
