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 velocity but no 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.
Can an object have zero acceleration and non zero 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.
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.
Can a body have non zero net force with zero velocity?
Answer: No , if the net force acting on a body be zero, then the body won’t necessarily be in the rest position. The situation of the net force equal to zero is impossible in reality. When the net force of the body is equal to zero, it implies that the body cannot be accelerated.
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
What is the velocity when the acceleration is first zero?
If acceleration is zero, then initial velocity equals average velocity ( v 0 = v – ) ( v 0 = v – ) , and. x = x 0 + v 0 t + 1 2 a t 2 becomes x = x 0 + v 0 t .
Will the next force be equal to zero?
The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero . A vector can only have zero magnitude if all of its components are zero.
Does constant velocity mean no net force?
If an object is moving with a constant velocity, then by definition it has zero acceleration. And according to Newton’s second law, ∑F=ma. ∑F=m(0)=0. So there is no net force acting on the object .
Can an object be moving if the net force is zero?
An object with no net forces acting on it which is initially at rest will remain at rest . If it is moving, it will continue to move in a straight line with constant velocity.
When velocity is maximum What is acceleration?
So, when velocity is maximum, acceleration is minimum (zero) .
Can a body have acceleration at rest?
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. An example is a vertically thrown ball at the top of its trajectory, or a yo-yo just as it turns around.
Where in the motion is the velocity equal to zero?
If velocity is 0 , that means the object is not moving, but with acceleration present, there is a force acting on the object. A common example is the vertex of an inverted parabola (along the x -axis).
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.
What happens when acceleration is 0?
If there is zero acceleration, that means there is no net force on the object , or .
