What else can I help you with?
Why don't we crush even though atmosphere exerts force on us?
Gravitation
Does the force of gravity or the friction keep a bicycle on the ground?
The force of gravity keep a bycicle on the ground.
What is the force to keep us on the ground?
The force to keep us and nearly everything else on the ground is GRAVITY.
What force keeps the desk on the ground?
Gravity.
Does the air force have ground troops?
21st century air force does, but not during the Viet War. The USAF ground troops are special ops personnel.
Which one exerts more force on the ground person standing up or laying down?
The force exerted by a person on the ground is the same whether they are standing up or laying down, as it is determined by their weight. The only difference is the distribution and contact area of the force between the feet when standing versus the whole body when laying down.
Does a pile of soil that sits on the ground exert force or not?
Yes, a pile of soil sitting on the ground exerts force on the ground beneath it. The soil has mass, and gravity pulls it down on the whatever is under it. A red ant standing atop the pile of soil exerts an extra force on it, to continue the figure.
What are two pairs of action-reaction forces involving a bucket?
When a person lifts a bucket upward, the person exerts an upward force on the bucket, and the bucket exerts a downward force on the person. When a bucket is pushed along the ground, the person exerts a forward force on the bucket, and the bucket exerts an equal and opposite backward force on the person.
A moose weighing 3kN is standing still the force the ground exerts on the moose is?
The force the ground exerts on the moose is equal in magnitude but opposite in direction to the force the moose exerts on the ground. Therefore, the force exerted by the ground on the moose is also 3kN, assuming the moose is not accelerating vertically.
When you are standing on the ground how much upward force is exerted on you by the earth?
When standing on the ground, the Earth exerts a force equal to your weight in the downward direction (gravitational force) and you exert an equal force in the upward direction on the Earth (reaction force) as per Newton's Third Law of Motion.
What are examples of normal force?
Examples of normal force include the force exerted by a surface to support an object placed on it, such as the force exerted by the ground on a person standing, or the force exerted by a bookshelf on a book placed on it.
If a person weighs 150 pounds and is standing on the floor and the floor is not moving what is the force that the floor exerts on the person?
150 lbs. In order for the floor to support you it must resist an equal force.
Who exerts more pressure on the ground a 500N woman standing in 0.005m high heels or a 500N woman standing in 0.05m work boots?
The woman in high heels exerts more pressure on the ground because the pressure exerted is force divided by area; the smaller contact area of the heels concentrates the force, resulting in higher pressure. So, a 500N woman standing in 0.005m high heels exerts more pressure than a 500N woman standing in 0.05m work boots.
Three examples of force pairs that happen when homework is being done?
The hand exerts a force on the pen to write on paper, while the pen exerts an equal but opposite force back on the hand. The book exerts a force on the table due to gravity, while the table exerts an equal but opposite force upwards on the book. The foot exerts a force on the ground to stay balanced while sitting on a chair, and the ground exerts an equal but opposite force upwards on the foot.
Is the force on the ground that exerts upon us called the normal force?
yes
A free-falling golf ball strikes the ground and exerts a force on it. Which sentences are true about this situation?
The ball exerts a force on the ground that is equal in magnitude and opposite in direction to the force that the ground exerts on the ball. The force on the ground causes a deformation in the surface, resulting in a corresponding reaction force from the ground on the ball. The impact of the golf ball on the ground demonstrates Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
How does the ground exerts force?
The ground exerts a force on objects due to gravity pulling them towards the Earth's center. This force is called the normal force and acts perpendicular to the surface of the ground to support the weight of the object. Additionally, friction between the object and the ground can also create a force that resists motion.
