Answer 2

Answer:

When a person walks on the ground, the force of friction exerted by the ground on him is in forward direction.

Explanation:

• The contact between two surfaces produces frictional force. Therefore, when the foot reacts normally to the ground, frictional force results, which causes us to move ahead.
• According to Newton's third law of motion, when you attempt to walk, you will exert a downward force $F$ on the ground, and as a result, a resultant force $F'$ will be generated that is equal to and opposite to the applied force $F$. As a result, we may write, $F=F^{'}$
• Because of the friction that exists between the soles of our shoes and the ground, we are able to walk on the ground.
• Walking involves lifting one foot off the ground and pushing the ground backward with the other foot.
• Our shoe on the ground would slide backward if there was no friction between the sole and the ground.
• Since we push the ground backward, friction works in the opposite way, forward, and keeps our feet from sliding backward.
