Answer: Yes , an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction. ...
Can a body have zero velocity and still acceleration give example?
It is possible to have a non-zero value of acceleration when the velocity of a body is zero. ... Therefore, the body is still accelerating. Example- When a ball is thrown upwards on earth with a constant velocity, the gravitational force of the earth acts on it in the opposite direction.
Can a body have acceleration with zero velocity Why?
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.
What is the acceleration if velocity 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 a body be accelerating when its speed is zero?
b) Can an object be accelerating when its speed is zero? ... Yes , acceleration is a change in velocity, so an object might be momentarily at rest but a split-second later have some speed, i.e. it can be changing its velocity even if it is momentarily at rest.
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.
Can a body have a constant speed and still have a varying velocity?
Yes, a body has constant speed as well as variable velocity . Consider an example: A particle moving in a circular path with a uniform circular motion.
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
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.
When velocity is maximum What is acceleration?
So, when velocity is maximum, acceleration is minimum (zero) .
Can a body have uniform acceleration?
As the rate of change of velocity is known as acceleration and in order to have a uniform acceleration the rate of change of velocity should also be uniform rate this is the only condition for a body to have uniform acceleration.
Can an accelerating car have constant speed?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes.
What happens when acceleration is 0?
If there is zero acceleration, that means there is no net force on the object , or .
At what point during its motion is the object’s acceleration zero?
At a projectile’s highest point , its velocity is zero. At a projectile’s highest point, its acceleration is zero.
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 the other name of negative acceleration?
The other name of negative acceleration is retardation . Note:It is important to remember that the term retardation is also known as deceleration.
