Question

9. Force of friction between two bodies increases the speed of a moving body.true or false​

Answer 1

Answer:

Option A is correct.

Explanation:

true is the answer

Answer 2

Answer:

Force of friction between two bodies increases the speed of a moving body.

Explanation:

Concept:  As we know that force of friction is directly proportional to the normal force which is written as;

                                            F=μN   .....(1)

Now as we can see that the friction is proportional to the normal force therefore as magnitude of force increases the the speed will increase and as a result friction between two body increases or vice versa.

Conclusion:

It is true that the force of friction between two bodies increases the speed of the body.
