"yes move a remote controle car on a patch of low friction ground and move it in a
circle. basic physics"
I believe the answer above is not true. Newton's first law (basic physics) states:
Every object in a state of uniform motion tends to remain in that state of
motion unless an external force is applied to it.
A circular path is not a uniform motion. Moving a car around in a circle means that
it is being accelerated towards the center of the circle. If you could do the above
experiment under perfect "frictionless circomstances" then the toy car would
eventuall come to a stop, without using the brakes (provided the car is not being
propelled forward by its engine).
I'm no scientist, but I do not think it is possible for an object to move in a circular
path without having to accelerate it towards the center of the circle, unless you
can somehow bend time-space (like gravity does).
When an object is moving in a circular path, it's constantly changing it's direction.
thus the velocity is changing. Change is velocity states that the object is accelerating.
=======================================
The problem that everybody above this line is having is: They're trying to stay
consistent with the universally held but mistaken idea that 'acceleration' means
'speeding up'. It doesn't !
'Acceleration' means 'any change in speed or direction of motion'. That could mean
speeding up, slowing down, starting out from a stop, rolling to a stop on grass, or
moving along any path that's not a straight line. They're all 'acceleration'.
An object moving in a circular path is constantly changing its direction of motion,
so there's acceleration there. An object can not move in a circular path without
acceleration, because the very bending of the path away from a straight line is
acceleration. Regardless of what's happening or not happening to its speed.
What else can I help you with?
Uniform circular motion deals with objects moving with what speed in a circular path?
When an object is moving in a uniform circular motion while traveling in a circular path, this means it has a constant speed. When an object is moving in a circular path, this indicates it is constantly being pulled towards the center of the circle.
Force is a fictitious force that some people believe causes you to feel as if you are being pushed outward from the center of a circle while traveling in uniform circular motion?
Force is not a fictitious force; it is a centripetal force that acts towards the center of a circle to keep an object in uniform circular motion. The sensation of feeling pushed outward is due to inertia, as an object's natural tendency is to move in a straight line. The centripetal force counteracts this tendency, causing the object to move in a circle.
How does Newton's first law explain circular motion?
A Partial ExplanationFirst, consider the object moving in a straight line with no forces acting upon it. According to Newton's First law, that object will always move in the same direction, at the same speed, forever. This is inertia.Now, for that object to move in a circular path, a force must act upon the object. If the force is in opposite direction of the object, the object will eventually slow down, stop, and begin reversing. The degree of slowing depends on duration and amount of force. Similarly, forces in the same direction of the object would increase velocity.Since the question asks about "uniform" circular motion, we'll assume uniform in both speed and geometry; and a uniform speed shows that no force is acting in the same direction, or the opposite direction of the object.So far, we know that there an object moving uniformly, and thus there's a force being acted upon it. Yet, we also know that force is neither "forwards or backwards." One more thing is the question asks for circular motion, not globular, so that makes this a two dimensional problem.So if there are only two dimensions to choose from, and we've eliminated the one the object is moving on, then there can only be a force acting perpendicular to the path of the object. If that path is circular, then that force will always be towards the center of the circle.Basically, think of the circle not as a long continuous path with constant force (even though it is) but as a whole series of little straight paths with a force knocking it to the side all the time, toward the center of rotation.
What is the difference between doubly linked list and circular linked list?
A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.
Can you take college classes without being in college?
Only if you do it online or by correspondence.
Can an object be accelerated if it is moving with constant speed?
No, an object cannot be accelerated if it is moving with constant speed. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity, and therefore no acceleration.
Under what circumstances can an object move in a circular path without being accelerated?
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.
If an object is being accelerated can its velocity be constant?
No. Acceleration is any change of velocity.But its speed can be constant.
Is it possible that a body be in accelarated motion under a force acting on a body yet no work is being done by the force?
Yes, that is possible. For example, an object in circular motion, accelerated towards the center. The force (and the acceleration) is normal (perpendicular) to the movement; thus, the dot product between the force and the displacement is zero.
An object being swung in circles on the end of rope is an example of projectile motion.?
Actually, an object being swung in circles on the end of a rope is an example of circular motion, not projectile motion. Projectile motion refers to the motion of an object that is launched into the air and then moves under the influence of gravity. Circular motion involves an object moving in a circular path around a fixed point.
What happens to the velocity when an object is accelerated?
A moving object being accelerated will show a change in its velocity (it may move faster, or slower, or experience a change in direction). A stationary object will respond to acceleration only if there is no other force acting to prevent its response. For example: gravity is a constant force of acceleration, but objects cannot move toward the center of the earth if they are being blocked by another object.
When an object falling towards the earth that is being accelerated only by gravity is said to be in?
Free fall.
How is circular motion accelerated motion?
"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant. So, if the direction of the movement changes, the velocity changes by definition, even if the MAGNITUDE of the velocity (also known as "speed") doesn't change.
What two thing does acceleration depend upon?
Acceleration depends on the mass of the object being accelerated and the net force acting on the object.
How do you interpret how an object is moving from a distance time graph?
If the distance is not changing, the object is not moving. If the distance is increasing or decreasing linearly then the object is moving at a constant velocity. If the distance is increasing or decreasing parabolically then the object is being accelerated or decellerated.
Uniform circular motion deals with objects moving with what speed in a circular path?
When an object is moving in a uniform circular motion while traveling in a circular path, this means it has a constant speed. When an object is moving in a circular path, this indicates it is constantly being pulled towards the center of the circle.
An object can be accelerated even though its speed remains constant give an example of such a situation?
An example of an object being accelerated even though its speed remains constant is a car traveling down a hill. Even if the driver maintains constant pressure, the car will accelerate due to the incline of the hill.
