What else can I help you with?
What is law of action and reaction examples?
Your feet exert a force on the ground so in return the ground exerts a force on your feet.
Does sand exert an equal but opposite force on your feet as you walk?
Yes
When you jump on the ground the earth exerts a greater force back up on because it is so massive?
The force that you exert on the Earth is equal to the force that the Earth exerts on you; for every action there is an equal and opposite reaction, so says Newton. What is different is the amount of motion that results. You move, and the Earth (apparently) does not. Actually the Earth is moving all the time, in its orbit around the sun and by rotating on its axis, but it does not noticeably move because you jump on the ground. And that is indeed because it is much more massive than you are. False.
If two hundred pounds fell two feet how many pounds of force would it exert?
That depends on a few things. First, exert on what? The ground? Is the ground made of concrete? Grass? Soft dirt or mud? The reason that is important is we need to know how quickly the 200-pound object stopped in order to answer your question. How far did it sink into the ground? An inch? A half inch? Just 0.1 inch? Second, we need to know whether the object rebounded. Did it just go plop and sink into the ground, or did the object bounce back up like a rubber ball? Those two things will affect the answer. The force exerted is much greater if the object rebounds, but let us assume the object does NOT rebound. The object's kinetic energy (KE) just before hitting the ground is equal to the potential energy (PE) it had at two feet off the ground. Since PE = wh = 200 (pounds force) x 2 feet = 400 foot pounds, we can say that KE is 400 foot pounds right before impact. We know that energy is the ability to do work, and that work is force times distance (W = Fd), so we can write F = W/d. Just before impact, KE is 400 foot pounds, and after impact KE is zero. The change in KE, therefore, is 400 foot pounds. Now, let us assume the object sinks into the ground one inch, which is equal to 1/12 foot (because there are 12 inches to the foot). Hence, the force applied to the object -- or the force exerted by the object -- is 400 / (1/12) = 400 * 12 = 4800 pounds force. What if the object fell on concrete and sunk into it only one tenth of an inch? In that case the force exerted would be 400 / (0.1/12) = 48,000 pounds force, which equals 24 tons!
How much force do your leg muscles need to exert for your feet to rise more than 2 meters high into the air during a jump?
The answer cannot be uniquely determined from the information given.There are at least two problems with the question:1. It doesn't matter how much your feet move, what matters is how much your center of mass moves.2. The force required depends on how much you weigh.
What is law of action and reaction examples?
Your feet exert a force on the ground so in return the ground exerts a force on your feet.
When you jump you push on the ground with your feet this is an action force the ground pushes back on your feet with an equal and blank force?
Opposite. The ground exerts a reaction force equal in magnitude but opposite in direction to the force you exert on it when you jump. This reaction force is what propels you into the air.
When you walk your feet push the ground and the ground pushes your feet Which law?
The law that explains this interaction is Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When you walk, your feet exert a force on the ground in the backward direction, and in response, the ground exerts an equal and opposite force on your feet in the forward direction. This interaction allows you to move forward by pushing against the ground.
How is newtons third law of motion at work when you walk?
the concept's application here is very simple. As we walk we exert a certain amount of force on the Earth and governed by the 3rd law the Earth exerts the equal amount of force back on our foot (opposite direction) but as the Earth is very massive to observe the push that we exert only the force the it exerts it felt this added to friction provides the stability of the feet while in movement
When you walk your feet push against the ground's the same time the ground pushes against your feet. what is the action force?
The action force is the force exerted by your feet on the ground. This force is the force that you apply to the ground when walking.
When standing on the floor does the floor exert an apward force against your fit how much force does exert why you are not move forward by the floor?
Yes, the force exerted by the floor on our feet is equal to the force that our feet exerted on the floor, or it just depends on your weight, If you are heavier than the normal. When you stand, the longer the time you stand, the more pain you feel on your feet. And we can't be move upward by the force that the floor exerted on our feet because of the force of our weight that keeps us on the ground, and also because of gravity.
Does sand exert an equal but opposite force on your feet as you walk?
Yes
When you standing on the floor does the floor exert an upward force against your feet How much force does it exert?
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
Which surface would exert the least frictional force on your feet as you walk?
Teflon, Ice or an oiled surface.
Why can you jump higher on the moon than the earth?
When you jump, you exert a force greater than the force of gravity to achieve a net positive upward acceleration - at least until your feet leave the ground and you quit exerting force. The net upward force is Fnet = (force you push off with) - (force of gravity) Because the moon has less mass than the earth, the force of gravity is less. As a result, the force you exert to jump on earth would give a higher net upward acceleration on the moon and allow you jump higher.
There are 2 forces acting on Gary the goat one force is his weight and the other is the rock pushing against his feet What is force A and what is force B?
Force A is Gary's weight pulling him downward towards the ground. Force B is the reaction force from the ground pushing back up against Gary's feet as he rests on the ground.
How you can jump?
You are able to jump by using your feet to apply force to the ground and then using this force to allow you to lift off the ground.
