Answer:
Action force: Would be the force of your feet against the Earth given by the weight defined as:
Where g is a constat who represent the gravity in Earth
Reaction force: Would be the force of the Earth pushing against your feet. And on this case is represented by the normal force defined as:
Where represent the friction coefficient between the ground and the object.
And the friction force.
If we don't have any other forces involved in the y axis we can conclude that:
And as we can see we have that Action force = Reaction force
So then the third Law of Newton is satisfied.
Explanation:
For this case we have this:
Action force: Would be the force of your feet against the Earth given by the weight defined as:
Where g is a constat who represent the gravity in Earth
Reaction force: Would be the force of the Earth pushing against your feet. And on this case is represented by the normal force defined as:
Where represent the friction coefficient between the ground and the object.
And the friction force.
If we don't have any other forces involved in the y axis we can conclude that:
And as we can see we have that Action force = Reaction force
So then the third Law of Newton is satisfied.
