Question

Can a body move with constant acceleration but zero velocity? if so plz give examples thx?

Answer 1

any body at rest in a gravitational field. Like a stone lying on the ground is being accelerated due to gravity but is motionless with zero velocity.

Answer 2

Doctor Q is right in one aspect, but keep in mind that acceleration and velocity are based on a reference frame.

Example:

You are standing on a train with an acceleration of 2 meters per sec squared.  Your velocity is 0 with respect to the train, but your acceleration is a constant 2 with respect to the ground.

In cases where both are with respect to the same reference frame (as is usually assumed), they both must be 0 for your case to apply.

Answer 3

Acceleration is a change in motion

There points in time where zero velocity occurs in an accelerating mass

Eg. throw a ball up and it s accelerates down.

So it slows, stops then moves down.

So there an instant where acceleration is happening and no motion.

Answer 4

In addition to the other answers you could also have constant acceleration in say the X direction with zero velocity in the Y or Z directions.

Say a car accelerating along a dead straight horizontal road has no velocity sideways or upwards.

Answer 5

yes it can. think of a pendulum, or swing when the swing is at the height and your are not moving your acceleration is at maximum, but your velocity is zero, when you are parallel to the ground your velocity is at maximum but no acceleration

Answer 6

Only if the constant acceleration = 0 and the body's velocity is also = 0.

Answer 7

hey there....Acceleration is change in velocity. if velocity is changed then only an object can accelerate...therefore it is practically impossible to accelerate without velocity unless you prove einstein wrong and come up with something

Answer 8

impossible

Answer 9

Probably not. They're all related with formulae; they depend on each other. So either they're both something, or both zero.

An object resting on the ground is not being accelerated - it's speed is zero, because the acceleration of gravity is balanced by the reaction of the ground.

Answer 10

A body travelling with uniform circular or elliptical motion(or revolution around a particular object) has a acceleration acting towards the object and its velocity is 0 because velocity is vector and it needs a particular direction.

                                      (And)

A body kept on the surface of any planet has 0 velocity but constant acceleration due to gravity(g).

Hence, there are two answers for your question.
