What else can I help you with?
A car moves in uniform circular motion around a curve in the road What is the direction of the car's acceleration?
If the speed is constant, the acceleration is toward the center of the circle.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
Under what conditions is it possible to have a constant speed yet a nonzero acceleration?
A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
Can the car accelerate if the speedometer of a car indicates a constant speed?
no. see the definition of acceleration. it can remain a constant speed while the velocity changes. *Edit* Actually, the answer is yes. The algebraic formula for acceleration is displacement over time but you are only thinking in terms of linear motion, or in the case of this scenario, a straight road. But when the car follows the road as it snakes or rounds a bend its acceleration is changing even if its speed is not. A more specific definition of acceleration is the change in velocity over the change in time. Velocity is a measurement of speed but with a direction and when an object goes into a circular motion path (or any motion path that isn't linear) its velocity is continually changing and a change in velocity means a change in acceleration. Plainly put, if the car turns a corner with a constant speed, the magnitude is constant but the acceleration vector is not.
What does a flat line represent on a speed time graph?
Motion at a constant speed - no acceleration or deceleration.
What is the acceleration that occurs when an object moves at a constant speed in circular motion?
It's called 'centripetal acceleration', whether or not the speed is constant or the path circular.
Is acceleration uniform in uniformly circular motion?
No, acceleration is not uniform in uniformly circular motion. In uniformly circular motion, the direction of the velocity vector is constantly changing, which means there is always a centripetal acceleration acting towards the center of the circle. This centripetal acceleration is not constant in magnitude, making the overall acceleration not uniform.
Why is circular motion with constant speed called accelerated motion?
Circular motion with constant speed is called accelerated motion because even though the speed is constant, the direction of motion is changing, leading to acceleration. This acceleration is due to the centripetal force required to keep an object moving in a circular path.
Give reason why uniform circular motion is considered as accelerated motion?
Because within circular motion, acceleration is constant
What circular motion is one in which an oblect moves in a circular path at constant speed?
Uniform circular motion is when an object moves in a circular path at a constant speed. The object's velocity is constantly changing direction due to its circular motion, while its speed remains constant. This type of motion is an example of centripetal acceleration keeping the object moving in a circular path.
In uniform circular motion quantities are constant?
In uniform circular motion, the speed of the object remains constant, but the velocity changes direction continuously. The acceleration is directed towards the center of the circle (centripetal acceleration) and its magnitude remains constant. The object moves in a circular path at a constant speed.
Can speed be constant but acceleration not be zero?
yes,in case of circular motion .
Is uniform circular motion accelerated?
Yes, uniform circular motion involves constant speed but changing direction, which means there is acceleration present in the form of centripetal acceleration directed towards the center of the circular path.
Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
What kind of acceleration travels at a constant speed in a circular motion?
In circular motion, the centripetal acceleration points towards the center of the circle and is responsible for maintaining the object's direction. This acceleration does not change the object's speed, but instead changes its direction, keeping it in circular motion.
What is the correct name for circular motion?
If the motion is truly in the form of a circle, the phrase uniform circular motion describes it appropriately. This means that the object is in a constant state of motion about a fixed point at a constant distance from that point. Circular motion can be considered an acceleration, because an acceleration describes any change in velocity or direction. Since circular motion involves constant change in direction, the object exhibits constant acceleration.
Is uniform circular motion and circular motion is the same?
no, in uniform circular motion the magnitude of your velocity, and therefore your acceleration is constant. in general this does not need to be true. consider this simple experiment, in a children's playground, go to a roundabout. stand on the roundabout and kick once, then wait for your motion to completely stop before kicking again. your motion is still circular, but neither velocity or acceleration is constant.
