can a body have zero velocity but non zero acceleration?

It's possible for a body to have its velocity zero even if the acceleration is non zero. For example consider a swinging pendulum bob. ... This actually happens because acceleration is not velocity - but rate of change of velocity.

Acceleration is defined as the rate of change of velocity. constant velocity is the velocity which doesn't change per time. So,if the velocity is constant,the acceleration is zero.

Acceleration is the change in velocity, not the velocity itself; therefore, an object can have zero velocity but not zero acceleration because the velocity will be changing.

For the most part velocity is not zero if an object is accelerating. ... If the velocity is constant however, the acceleration is zero (because the velocity isn't changing over time). Although at an instant in time it is possible to have zero velocity whilst accelerating.

The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed. The acceleration of an object is parallel and directly proportional to the net force acting on the object, is in the direction of the net force and is inversely proportional to the mass of the object.

Where a body travels equal distance in equal interval of time or we can say motion where speed will be constant . Where a body travels with constant acceleration which means a body would have same change in velocity, so certainly it will not travel same distance.

Yes we can have zero acceleration and non zero velocity in case of uniform motion in which an object is moving in straight line with constant speed ,here object has non zero velocity but there is no change in velocity so no acceleration.

According to newton's first law of motion, the acceleration of the body could be zero if there is no force acting on it. Acceleration in an object could be zero even when several forces acting on it. This happens when all the forces cancel out each other i.e the net force acting on the object is zero.

Uniformly accelerated motion - A body will move with a constant acceleration and its velocity will keep on changing with time at a constant/steady rate. ... Uniform Motion - A body will be moving with a constant/unchanging velocity moving in a particular direction and thus acceleration will be zero.

Explanation: If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that's not to say that there isn't work done by individual forces on the object, but the sum is 0 ).

Assuming rightward is the positive direction. Newton's first law says that if the net force on an object is zero ( Σ F = 0 \Sigma F=0 ΣF=0\Sigma, F, equals, 0), then that object will have zero acceleration. That doesn't necessarily mean the object is at rest, but it means that the velocity is constant.

And it's not zero, it's -9.8m/s/s, as you acknowledge, so the direction of acceleration is meaningful. The no math answer to this one is to realize that acceleration is the rate of change of velocity. At the top most point, the velocity is indeed zero.

Finding the acceleration Thus, even though the velocity of an object at rest must be zero, acceleration can clearly be non-zero for objects at rest. A particle that is thrown vertically upwards stops momentarily at the highest point of motion.

Is it possible for an object to have zero average velocity over a given interval of time, yet still be accelerating during the interval? Yes. A ball thrown straight upward and caught when it returns to its release point has zero average velocity, but it has been accelerating the entire time.

Zero acceleration means “no change in velocity”. If a person is moving with a constant velocity its acceleration is zero but its velocity is not zero.

The value of the tangential acceleration may be: Greater than zero (> 0): When the body has accelerated motion, that is, the magnitude of the velocity vector increases with time. ... Equal to zero (= 0): When the body has uniform motion, that is, the magnitude of the velocity vector remains constant.

No, acceleration is not lnversely proportional to time , it may be zero if velocity is not changing while time is increasing uniformly . Also acceleration may be constant , like the acceleration du to gravity which is 9.8 m/s2 .
