Which of newton's laws explain how a walking person moves forward by pushing backward?

His third law "for every action there is an equal and opposite reaction" because the same force that you applied to the ground is applied to you.

What is a demonstration of newtons first law?
That you are pushing the earth down while the earth is pushing you up, so you stay where you are.
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
A friend tells you that a rowboat is propelled forward by the force of its oars against the water First explain wheather the statement is correct and then identify the action and reaction and reac?
He is incorrect. Newton's 3rd law states that any force has an equal and opposite force. This means he pushes back on the water with the oars (normal), and this creates a forward normal force on the oars pushing the oars and the boat forward.
How did a comet get its size?
It probably kept crashing into other meteors and pushing them forward with it's extreme power.
Give a short example of equal and opposite pairs?
Perhaps forces.When you fire a gun, you have an explosion of gunpowder that ejects the bullet forward at a high velocity. The gun kicks back in an opposite direction from the firing with a force equal to that which expelled the bullet, but in the opposite direction.Another example might be ice skating (without braking). If one person pushes the other backward... the pushing person will also be pushed backward with equal force. Acceleration/velocity, of course would be dependent on the relative weights.
Which Newtons law of motion can explain what happens when someone pushes a chair across the floor?
It will have no equilibruim and when you are pushing it you are using a force
An 80kilogram skier slides on waxed skis along a horizontal slope of snow at constant velocity while pushing with his poles What is the horizontal component of the force pushing him forward?
40 newtons. give the explanation of this
How can you control gear change in an automatic car?
There are some automatic gear buttons. You can change them by pushing or pulling the handle of the gear forward or backward next to the correct button.
How bikes go forward when you are pushing the paddles backward?
A. only when you sit on the haldlebars and pedal ;-D A Unless it's a custom bike, or a bike with a real improbable fault, they don't.
Why do you need to do walk?
If there was no friction, your foot would simply slide back as you tried to take steps, and you would go nowhere. In order for something to move, it has to have a force moving it. That force has to have leverage, or friction. For the force pushing a person forward, there is an equal force pushing backward on the ground or floor. You can observe this by placing round pencils under a board, stand on it, and try to step off in the perpendicular direction : the board will roll backward as you step forward.
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.
What exerts the force that pushes you forward when you walk?
Your feet are pushing backward against the floor, where friction prevents that backward motion and exerts an equal force that pushes you forward. If the floor were not fixed in place, it would move backward instead and you would stay in the same place. If friction did not exist, your foot would merely slide backward across the floor, and again you would stay in the same place.
How does newtons law of motion apply to a cat running?
Newton's laws apply to a cat running because, the cats gravity to the ground, it's acceleration forward and the action/reaction of the cats paws pushing back off the ground springing it forward.
What is a demonstration of newtons first law?
That you are pushing the earth down while the earth is pushing you up, so you stay where you are.
Two forces act on the same object. One force is pushing due east with a force of 6 newtons and the other is pushing due north at 8 newtons. What is the resulting force?
10 newtons NE. a little more north than east
Why does the boat move away from the jetty when someone tries to jump off it?
Action-Reaction. When someone tries to jump off it, their forward push is equaled by the backward push exerted on the object they are pushing against.
In a 2002 VW Passat wagon how do you drive the manual option if it is automatic and manual?
If you shift the gear stick to the right, it is on manual. Then by pushing it forward and releasing you shift up; by pulling backward and releasing you shift down.
