Question

Using newton’s third law Why am I able to walk for
ward

Answer 1

You can walk forward due to Newton's third law of motion, where the ground pushes you forward as a reaction to you pushing backward against it. This law explains the motion of cars, rockets, swimmers, and various other scenarios, illustrating the universal application of action-reaction force pairs.

Step-by-step explanation:

You are able to walk forward because of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When you push backward against the ground with your foot, the ground pushes forward on your foot with an equal and opposite force. This reaction force propels you forward, allowing you to move.

Additionally, similar principles apply to various modes of motion across different realms. Cars accelerate when the ground pushes forward on the drive wheels in response to the wheels pushing backward, rockets generate thrust by expelling gas backward which in turn pushes the rocket forward, and swimmers push off the pool wall to create a forward movement.

All these scenarios demonstrate the action-reaction pairs described by Newton's third law, which are crucial to the movement of objects and organisms in their respective environment.

Answer 2

See the explanation below.

Step-by-step explanation:

Newton's third law states that any force applied to a body generates a reaction equal and in opposite direction to the original Force.

In order to better understand how a person's movement is generated when walking, we will analyze the attached image below, where we see the forces acting.

The red vector goes in the direction of the person's movement, this force vector pushes the person to move forward.
