When you push against a wall with your fingers they bend because they experience a force. What is this force?
It is the force of the wall pushing against your fingers. This is related to Newton's Third Law.
What are the forces act on a retaining wall?
Outward Force: dirt pushing against retaining wallInward Force: atmospheric pressure, the retaining wall pushing against the dirtDownward Force: gravity, atmospheric pressure, the retaining wall pushing against the earth.Upward Force: The earth pushing against the retaining wall.
How friction is useful in pushing a car?
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
When a person pushes a crate across the floor what force is working in reaction to the pushing force?
friction
Newton's Third Law says that for every action there is an equal and opposite?
The answer is reaction. A simple example is you standing on the ground. You are not moving or accelerating (in our reference frame). You are pushing down against the ground with a force (the action) equal to your weight. The ground pushes back up (opposite direction) with an equal force (the reaction force).
What is an example of an action reaction forces?
The recoil of a bullet being fired from a gun is a good example, the action force is the gun pushing the bullet away from the gun and the reaction force is the bullet pushing back against the gun (recoil).

It is the force of the wall pushing against your fingers. This is related to Newton's Third Law.
How to calculate the normal force acting on an object held against a wall given mass and force?
Force of horizontal normal to the wall reaction on the object will be exactly equal to the force you're pushing it against the wall with.
What is a good example of input force?
Someone pushing against a lever.
What are the forces act on a retaining wall?
Outward Force: dirt pushing against retaining wallInward Force: atmospheric pressure, the retaining wall pushing against the dirtDownward Force: gravity, atmospheric pressure, the retaining wall pushing against the earth.Upward Force: The earth pushing against the retaining wall.
How do you show that for every action there is an equal and opposite reaction force?
when you push your hand against a wall the wall is 'pushing' against you that is why you feel your hand being pushed.
What is the action and reaction force of touching your finger to your nose?
The action is the finger pushing the nose. The reaction is the nose pushing back on the finger.
Normal force is supplied by what?
A surface pushing up, equal and opposite to a force pushing against it

What action and reaction are present when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
