Can an object move in a circular path without being accelerated?

"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.

No, according to Newton's first law of motion, an object will only move in a straight line at a constant speed unless acted upon by an external force. In the case of an object moving in a circular path, it is constantly changing its direction, which requires acceleration towards the center of the circle to maintain that path.

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?
Newton's first law of motion states that an object in motion will continue moving in a straight line at a constant speed unless acted upon by an external force. In the context of circular motion, a centripetal force is required to constantly change the direction of the object's velocity, keeping it moving in a circular path. Without this centripetal force, the object would continue in a straight line due to its inertia.
What is the difference between doubly linked list and circular linked list?
A doubly linked list allows traversal in both directions (forward and backward) by having each node point to both its next and previous nodes. A circular linked list is a type of linked list where the last node points back to the first node, forming a circular structure. This allows continuous traversal through the elements without a definitive end.
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?
Yes. The simplest such case is when the object is moving along a circle.
If an object is being accelerated can its velocity be constant?
No. Acceleration is any change of velocity.But its speed can be constant.
When an object falling towards the earth that is being accelerated only by gravity is said to be in?
Free fall.
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.
Upon what factors value of g depends?
Gravitational acceleration (g) depends on the mass of the object that you are being accelerated toward (Earth), and the average distance from that object. (the radius of the Earth)
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.
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.
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 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.
Second law of motion?
Second Law of Motion: Acceleration is produced when a force acts on a mass. the greater the mass ( of the object being accelerated) the greater the amount of force needed ( to accelerate the object).
Why is an object going in a circular motion constantly accelerating?
This is not strictly true; an object in orbit, going in a circular motion, at least from a human perspective, is not accelerating. However, any object going in a circular motion that is not orbiting another object is being contained in a circle artificially, either by a tether or by thrust, that would go in a straight line if no other force were acting on it, is experiencing "acceleration," which is not necessarily "going faster" as might be assumed.
To moves around the sun in nearly circular path?
Any satellite circling another object is considered to be 'orbiting' that object in a circular orbit.Wikipedia made the following statement, under topic, "circular orbit":"In astrodynamics or celestial mechanics a circular orbitis an elliptic orbit with the eccentricity equal to 0."Here, the 'eccentricity' would be referring to the degree to which the orbit moves outside that of forming a perfect cirular path. As a circular path would have no variance from being circular, of course, it has no "eccentricity/ies"
