Can a body have acceleration while at rest give example?
a body projected upward is in rest at the top most point, but acceleration is not zero
Can a body have acceleration with zero velocity?
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
When acceleration of the body cannot be zero?
As we know from the Newton's 2nd Law, F=ma,F=force,m=mass of the body a= acceleration of the body a=F/m When F>0 i.e. even a little amount of force is exerted on the body and it is moving even with a little velocity,acceleration cannot be zero because mass is always >0
Meaning of zero acceleration?
Zero acceleration means no change in velocity and no force on the zero accelerating body.
What is the difference between rest and equilibrium?
Velocity of body and acceleration of body is zero implies body is at rest Acceleration of body is zero implies it is in a state of equilibrium Body in equilibrium can have non zero velocity

Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
Meaning of zero acceleration?
Zero acceleration means no change in velocity and no force on the zero accelerating body.
What is the difference between rest and equilibrium?
Velocity of body and acceleration of body is zero implies body is at rest Acceleration of body is zero implies it is in a state of equilibrium Body in equilibrium can have non zero velocity
What will be the acceleration of a body at rest?
zero
What is the acceleration for a body at rest?
Zero.
Is it possible for a body to have zero velocity and non-zero acceleration?
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
When a body has constnat velocity what is the acceleration?
The acceleration is zero for a body having constant velocity.
Can velocity of an object be zero at the same instant its acceleration is not zero?
Yes. For example a swinging pendulum has zero velocity at the turning point but acceleration is not zero.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
