An object can move in a circle at different speeds.
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
centripetal acceleration
When the direction changes. A simple case is an object moving in a circle, at constant speed.
Yes, it can. Perhaps the simplest example is when an object moves at constant speed, in a circle. In this case, the speed doesn't change; the velocity does.
Yes; for example, an object moving in a circle.
The direction of acceleration of an object moving on a circular path at constant speed is pointed towards the center of the circle. This acceleration is called centripetal acceleration and is necessary to keep the object moving in a curved path.
The net force on an object moving with constant speed in circular motion is directed towards the center of the circle. This force is called the centripetal force and is required to keep the object moving in a circular path instead of moving in a straight line.
No, the velocity of an object in uniform circular motion (UCM) is not constant. While the speed of the object remains constant, the velocity changes continuously in direction due to the centripetal acceleration required to keep the object moving in a circle.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
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.
The force toward the centre of the circle is called the centripetal force. centrpetal acceleration.
