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.
Can a body have zero velocity and still be accelerating explain with an example?
Yes, a body with a velocity 0 can still accelerate. The simplest example is
a body which is thrown up
. At the peak point its velocity becomes 0 but still accelerates due to gravity.
Does 0 velocity mean 0 acceleration?
In option (C),
zero velocity does not imply that the acceleration is zero
. For e.g., when a ball is released from a height, its velocity will be zero but the acceleration exerted due to gravity will be non-zero so option (C) is correct. In option (D), constant speed does not imply that acceleration is zero.
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
.
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
How can you have acceleration but no velocity?
Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. … Although
at an instant in time it is possible
to have zero velocity whilst accelerating. For example, if you drop an object at the instant you release it it has zero velocity but it is accelerating.
When velocity is maximum What is acceleration?
So, when velocity is maximum, acceleration is
minimum (zero)
.
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.
Does constant speed mean no acceleration?
The velocity vector is constant in magnitude but changing in direction. 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.
Can you have zero velocity and nonzero acceleration?
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.
Is 0 a constant acceleration?
Zero acceleration is an acceleration
, just with zero magnitude. Motion with constant velocity is just a special case of motion with uniform (i.e. zero) acceleration.
At what point velocity is maximum?
If acceleration is positive to the left and negative to the right
, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just before 3π/2 and positive just after.
Why velocity is maximum when acceleration 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.
Why the acceleration is negative?
According to our principle,
when an object is slowing down, the acceleration is in the opposite direction as the velocity
. Thus, this object has a negative acceleration. … When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object also has a negative acceleration.
What is a real life example of acceleration?
When the car slows down
.
When you fall off a bridge
.
The car turning at the corner
is an example of acceleration because the direction is changing. The quicker the turns, the greater the acceleration.
