can you explain how the kidneys remove wastes and keep fluids and salts in balance?
How can you use newtons first law to explain why centrifugal force does not exist?
Newton's first law states that an object in motion will remain in motion unless acted upon by an external force. In the case of an object moving in a circular path, centripetal force is required to keep the object moving in that path, not centrifugal force. Centrifugal force is a perceived force that arises from the object's inertia, rather than a true force acting on the object itself.
What happens to a moving object if no other force acts on it?
The law of ineritia dictates that it will keep on going its course if no force acts upon it. Of course this is only vaild in a static frame of reference, if the observer is accelerating at the same time then the object even know nothing is acting upon it will according to the observer accelerate without an apparent force acting on it. But to sum up in layman's term no it won't do anything.
What three things keep the planets in their orbit?
A planet is kept in its orbit because the Sun's gravitational attraction on it produces acceleration towards the Sun, which exactly balances the force, by Newton's laws of motion. An object that is travelling along in a curved path is accelerating to the side, according to Newton's theory, and in a stable orbit this can go on for ever without the energy ever diminishing.
Why fungi do not grow easily on food that is keep dry?
They cannot trap moisture.
What keeps a falling object from accelerating?
Air resistance and buoyant force are two factors that can oppose the acceleration of a falling object. These forces act in the opposite direction to the force of gravity, thus slowing down the object's acceleration.
Why is centriugal force fictional?
From the point of view of an outside observer, no centrifugal force is necessary to "explain" anything; the natural tendency of an object is to go ahead in a straight line. A centripetal force is required to keep an object moving in a circle; no counterforce is required to "balance" things, since the object is in fact accelerating. The centrifugal force is introduced for the rotating frame of reference - i.e., from the point of view of somebody who is participating in the rotational movement.
If An object in uniform circular motion must be changing its speed in order to move in a circular path?
Yes, an object in uniform circular motion is constantly changing its direction, which means it is accelerating towards the center of the circle. This acceleration is necessary to keep the object moving in a circular path at a constant speed.
An object propelled into the air but has no power to keep itself in the air?
The object will fall back to the ground due to gravity acting on it. Without a source of lift or propulsion to counteract gravity, the object cannot stay in the air.
What is the definition of save an object?
keep the object
1985 olds V 6 stalls when you floor it and dies what may be the problem?
try accelerating slowly. if it doesnt stall, you may have to keep accelerating slowly[until someone else can diagnose tyhe problem]
Why is force centripetal?
Centripetal force is not very difficult to understand, yet most people make it seem overly complex. Centripetal force is an inward force applied to an object that is in circular motion (uniform circular motion). This inward force is what centripetally accelerates an object, which means the object is accelerating around the circle. DO NOT EVER BELIEVE THAT THERE IS A CENTRIFUGAL FORCE. THIS FORCE IS FAKE, BECAUSE THERE IS NO FORCE THAT IS PUSHING OUT ON OBJECT TRAVELING IN UNIFORM CIRCULAR MOTION!!!!!!!!!!!!! All it means is that there is no centripetal force to stop an object from moving out of the circle. An example is a car. If you are sitting in a car, when you go around a bend at a pretty decent speed, you seem to lean in the opposite direction of the turn. this is actually false. you are travelling in a straight line due to your inertia. When the car turns, you continue in that straight line, obviously you don't fly out of the car, because the car applies an inward force on you when you hit the side to keep you centripetally accelerating. Friction is one of the few forces that can stop an object from centripetally accelerating. when i mentioned a straight line due to inertia, I am talking about the velocity of the centripetally accelerating object. This velocity vector is tangent to the circlular path of the object. So that means that if you wanted to whirl a rope over your head like a cowboy and throw a rock at something, you would have to let go of the rope when it was perpendicular to the target. target------------------{((()))}------------------ | | ------- | rock O
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
Why are you still accelerating when you travel in a circle at a constant speed?
When you travel in a circle at a constant speed, your velocity (direction and speed) is constantly changing as you move along the curved path. This change in velocity indicates that there is an acceleration acting on the object, known as centripetal acceleration, which is directed towards the center of the circle. This acceleration is required to keep the object moving in a curved path at a constant speed.
