What else can I help you with?
Is it true or false that For a particle in uniform circular motion the instantaneous-acceleration vector is directed radially outward?
True. In uniform circular motion, the particle's velocity is tangential to the circular path, and the acceleration is directed radially inward, towards the center of the circular path. This centripetal acceleration causes the change in direction of the particle's velocity, but the magnitude of the velocity remains constant.
What is an object in uniform circular motion?
An object in uniform circular motion moves at a constant speed around a fixed center, following a circular path. Its velocity is always tangential to the circle and its acceleration is directed towards the center of the circle, causing a change in direction but not in speed.
What does uniform circular motion mean?
Uniform circular motion is the movement of an object along a circular path at a constant speed. The object experiences a centripetal acceleration directed towards the center of the circle, which keeps it moving in a circular trajectory. The velocity of the object is tangential to the circle at any given point.
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.
Since an object moving in uniform circular motion keeps a constant speed there is no force necessary to keep it in motion?
While the speed is constant in uniform circular motion, the direction of the object's velocity is always changing, which means there is acceleration towards the center of the circle. This acceleration is provided by a centripetal force that acts as a centripetal acceleration. Without this force, the object would move in a straight line tangential to the circle.

Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
In uniform circular motion, how are force and acceleration directed?
In uniform circular motion, the force is directed towards the center of the circle, while the acceleration is directed towards the center as well.
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.
What is the direction of acceleration in circular uniform motion?
The direction of acceleration in circular uniform motion is directed towards the center of the circle, which is also known as centripetal acceleration. This acceleration is responsible for keeping an object moving in a circular path instead of moving in a straight line.
When an object is moving with uniform circular motion the centripetal acceleration of the object?
The centripetal acceleration of an object in uniform circular motion is directed towards the center of the circular path and is perpendicular to the object's velocity. It is responsible for changing the direction of the object's velocity, keeping it moving in a circular path.
What are the assumptions used to develop the kinematics model of circular motion?
The main assumptions in developing the kinematics model of circular motion are that the object is moving along a circular path at a constant speed, which implies uniform circular motion. Additionally, it is assumed that there is no tangential acceleration, meaning that the speed of the object remains constant. Finally, the assumption is made that the object's motion can be described using angular quantities such as angular displacement, velocity, and acceleration.
Can a body moving with constant speed has acceleration?
Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.
