[" If man is walking,"],[" direction of friction is "]

For a man walking on the floor, the force of friction between the floor and his feet accelerates him forword. What will be work done by the force of friction, postive, negative or zero?

A man walks 10 m towards east and then turns at an angle of 30^(0) to the north of east and walks 10 m . Calculate the net displacement of the man. Also find the direction of net displacement.

When a person walks on a rought surface, the frictional force exerted by surface on the porson is opposite to the direction of his motion. It is the force exerted by the road on the person that causes the motion.

When a person walks on a rough surface, the frictional force exerted by surface on the person is opposite to the direction of his motion. It is the force exerted by the road on the person that causes the motion.

Consider the following statements A and B and identify the correct answer. A. When a person walks on a rough surface the direction of frictional force exerted by the surface on the person is opposite to the direction of his motion. B. When a cycle is in motion, the force of friction exerted by the ground on the front wheel is in the backward direction.

“When a person walk on rough surface then frictional force act in opposite direction of motion” - True or false ?

A man walks 6 km towards the north, then turns towards his left and walks for 4 km. He again turns left and walks for 6 km. At this point he turns to his right and walks for 6 km. How many km and in what direction is he from the starting point ?

Pavani is walking towards south direction. She then turns left and walks for another 5 km and then turens left again and continu walking. In which direction she is walking now?
