4) a) Can an object be moving when its acceleration is zero? …
Yes
, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.
Can an object be moving if the acceleration is zero?
4) a) Can an object be moving when its acceleration is zero? …
Yes
, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.
What happens if there is zero acceleration on a moving body?
If there is no acceleration, then
the object will move with a constant velocity
. Mathematically, we can look at Newton’s second law and the formula for acceleration. We know that the force is zero.
Can a body have zero velocity but non-zero acceleration?
Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs.
It is possible to have a non-zero value of acceleration when the velocity of a body is zero
. … This means that the change in the velocity is still taking place when the velocity of the object reaches zero.
Can a body move without acceleration?
4) a) Can an object be moving when its acceleration is zero? …
Yes
, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.
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 move in curved path without acceleration?
No,
a body cannot move on a curved path without acceleration
because while moving on a curved path, the velocity of the body changes with time.
Is there acceleration at constant velocity?
If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a
constant velocity is not accelerating
. … Since accelerating objects are constantly changing their velocity, one can say that the distance traveled/time is not a constant value.
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.
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
When velocity is maximum What is acceleration?
So, when velocity is maximum, acceleration is
minimum (zero)
.
Can a body move on a curved path with constant acceleration?
The magnitude of the velocity of the body is constant but the direction is constantly changing. This means that, even though the speed is not changing, the velocity is changing. We conclude that a body moving in a circular (or, in fact, any curved path)
is accelerating
.
Is it possible to move on a curve with constant acceleration?
Is it possible to round a curve with (b) zero acceleration and (c) a constant magnitude of acceleration? ——— (a)
Yes
. Rounding a curve at constant speed means you are accelerating toward the center of the circle. Even though your speed is constant, your velocity vector is changing, so your acceleration is nonzero.
Is it possible to move on a curve with zero acceleration give an example?
It
is not possible
to round a curve with zero acceleration because to change the direction of the velocity vector, acceleration must act on the object. However, with constant acceleration, this can be possible, as it happens in uniform circular motion.
What is acceleration of body moving with constant velocity?
From classical mechanics, we know that the force is the rate of change of momentum, one of it’s simplest forms is F=ma, so if a body moves with constant velocity, then its acceleration is
zero
, and by the previous definition has no force, although for example if a car of constant speed strikes some person, he may be …
