It is not possible to round a curve
with zero acceleration because to change the direction of the velocity vector, acceleration must act on the object. However, with constant acceleration, this can be possible, as it happens in uniform circular motion.
What happens when there is 0 acceleration?
If there is zero acceleration, that means
there is no net force on the object
, or .
Can you go around a curve with 0 acceleration?
Yes, it is impossible to go around the curved path with zero acceleration
. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.
Can you have an acceleration of 0?
Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. …
If the velocity is constant however, the acceleration is zero
(because the velocity isn’t changing over time).
How do you know if acceleration is 0?
When acceleration is zero (that is, a = dv/dt = 0),
rate of change of velocity is zero
. That is, acceleration is zero when the velocity of the object is constant. Motion graphs
Does constant speed mean acceleration is zero?
Acceleration is a kinematic quantity. Irrespective of what forces are acting,
if the velocity is constant, the acceleration is zero
.
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 is an example of zero acceleration?
No acceleration means no change in velocity. For example an apple thrown in space.
A photon
has zero acceleration because it can’t be accelerated. All other examples of zero acceleration are where the “thing” is moving at a constant velocity relative to an inertial reference frame.
Can a body have zero velocity and still has an acceleration?
Answer:
Yes
, an object can have zero velocity and still be accelerating simultaneously. … While observing the object, you will find that the object will continue to move forward for some time and then stops instantly. Then the object will start to move in the backward direction.
Why acceleration is maximum when velocity is zero?
Acceleration is zero because at that point, it is the mean position, which means it is the equilibrium position. The velocity is maximum there because
acceleration changes direction at that point
, hence at all other points, the acceleration is decelerating the object.
Is acceleration zero at the highest point?
At a projectile’s highest point,
its acceleration is zero
.
Why is tangential acceleration zero?
Yet, with the centripetal force directed perpendicular to the velocity vector, the object is always changing its direction and undergoing an inward acceleration. So, during a uniform circular motion tangential acceleration is zero
due to its constant angular velocity
.
Why does acceleration stay constant?
Sometimes an accelerating
object will change its velocity by the same amount each second
. … This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.
Can a body have uniform speed but still have acceleration?
Answer: An object moving in a circular path with uniform speed, i.e covering equal distance in
equal amount of time is still under acceleration
. Because, the velocity keeps on changing due to continuous change in the direction of motion.
Can a constant speed be accelerating?
Yes
. Even though the initial and final speeds are the same, there has been a change in direction for the object. Thus, there is an acceleration. … This explains why an object moving in a circle at constant speed can be said to accelerate – the direction of the velocity changes.
When velocity is 0 What is acceleration?
At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to
g=9.8m/s2
.
