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.
How can an object have zero velocity and still be accelerating?
Answer:
Yes
, an object can have zero velocity and still be accelerating simultaneously. … Now, suddenly a force acts on it and tries to accelerate the object in the reversed direction. While observing the object, you will find that the object will continue to move forward for some time and then stops instantly.
Can a body have acceleration without velocity give example?
It is possible to have a non-zero value of acceleration when the
velocity
of a body is zero. … 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.
Can you have zero velocity and acceleration at the same time?
Answer: Yes,
an object can have zero velocity and still be accelerating simultaneously
. Let us consider an object moving in the forward direction. Now, suddenly a force acts on it and tries to accelerate the object in the reversed direction.
Can a body have constant velocity and still be accelerating?
If a body has constant velocity, it means that the magnitude of the velocity and the direction of the velocity vector will remain constant. Since speed is equal to the magnitude of the velocity vector, it will also be constant. … Hence, a body can have
a constant speed
and still be accelerating.
Can you have a zero acceleration and nonzero velocity?
It is
possible to have a non-zero value of acceleration when the velocity of a body is zero
. … 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.
At what condition is a body with constant acceleration but with zero velocity?
Answer: When
an object is thrown in upward direction, at the maximum height the velocity of the object
becomes zero but still in that condition a constant acceleration due to gravity is working.
Does constant acceleration mean zero velocity?
Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. In other words, if something is accelerating, it has to have a variable velocity.
If the velocity is constant however, the acceleration is zero
(because the velocity isn’t changing over time).
Can a body have zero velocity and still be accelerating Class 11?
Answer:
Yes
, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. … While observing the object, you will find that the object will continue to move forward for some time and then stops instantly.
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
Can a body travel with a northward velocity and a southward acceleration?
Yes
, for example, a car that is traveling northward and slowing down has a northward velocity and a southward acceleration. … For example, a ball thrown upward has a positive velocity and a negative acceleration while it is going up.
Can a body have I a uniform speed but still have acceleration II a zero velocity but still have acceleration give an example of each kind?
(i) A body can have acceleration even when it has uniform speed. A body in
uniform circular motion
has uniform speed but at every point its direction of velocity changes, so its motion is accelerated. (ii) Yes, a body can have acceleration even when its velocity is zero.
Which of the following 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.
What is the force if there is no acceleration?
Acceleration is the change in velocity per unit time. Since the velocity does not change from one moment to the next, then there must be no net acceleration on the object. Returning to Newton’s second law, we can see that if there is no acceleration, then there is
no net force
.
What happens to acceleration when velocity is 0?
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.
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.
