It is possible to move on a curved path with zero acceleration.
Can an object move in a circular path without being accelerated?
There is a tendency to believe that if an object is moving at constant speed then it has no acceleration . This is indeed true in the case of an object moving along a straight line path.
Can an object move with zero acceleration?
4) a) Can an object be moving when its acceleration is zero? ... Yes , an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.
Can there be a circular motion with zero acceleration yes or no?
An object undergoing uniform circular motion does not accelerate .
Is acceleration ever zero in circular motion?
The direction changes due to the centripetal acceleration
What happens to an object with zero acceleration?
If acceleration is 0, the velocity is not changing . If the velocity is constant (0 acceleration) then the object will continue without slowing down or speeding up.
Can a body have zero acceleration but have velocity?
It is possible to have a non-zero value of acceleration when the velocity of a body is zero. ... At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2.
Does the body in uniform circular motion have an acceleration?
An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction . The direction of the acceleration is inwards. ... The final motion characteristic for an object undergoing uniform circular motion is the net force.
Does constant acceleration mean 0?
Constant acceleration means that the acceleration does not change . Some would say that if the acceleration is zero then the acceleration does not change and so one can say that the acceleration is constant.
What is the difference between positive and negative acceleration?
An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).
What is negative acceleration called?
Note:The negative acceleration is also referred to as retardation and the body is said to be retarding. If object A was moving in a negative direction and speeding up, then the acceleration of the body would have been in the same direction as that of its velocity.
Can a body moving with constant speed be accelerating?
Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. ... For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating . It is accelerating because the direction of the velocity vector is changing.
Why is acceleration towards the center of a circle?
Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes , producing an acceleration. The acceleration is directed radially toward the centre of the circle.
Can acceleration be non zero when velocity is zero?
It is possible to have a non-zero value of acceleration when the velocity of a body is zero. ... At the point where the velocity becomes zero, only the instantaneous velocity of the body is zero, at any time before or after this time, the object has a non-zero velocity.
What happens to acceleration if there is no change in velocity?
If an object is not changing its velocity, then the object is not accelerating. The data at the right are representative of a northward-moving accelerating object. The velocity is changing over the course of time . In fact, the velocity is changing by a constant amount – 10 m/s – in each second of time.
Can a body subjected to a uniform acceleration always move in the straight line?
When a body is subjected to a uniform acceleration, it always move in a straight line .
