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.
Can a particle move on a curved path without acceleration?
There is a tendency to believe that if an object is moving at constant speed then it has no acceleration. This is indeed true in the case of an object moving along a straight line path. On the other hand, a particle moving on a curved path
is accelerating whether the speed is changing or not
.
Can you go around a curve with 0 acceleration?
Yes, it is impossible to go around the curved path with zero acceleration
. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.
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
.
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.
Can you travel in a circle with constant acceleration?
The velocity vector is constant in magnitude but changing in direction. … For this reason, it can be safely concluded that an object moving in a circle at constant speed
is indeed accelerating
. It is accelerating because the direction of the velocity vector is changing.
Is it possible for a body to undergo acceleration although its speed is constant?
If a body has constant velocity, it means that the magnitude of the velocity and the direction of the velocity vector will remain constant. … Again, since the acceleration is the rate of change of velocity of a body with time, if the velocity is constant, the
acceleration of the body will be zero
.
When a body is moving in a curved path?
The motion of an object moving in a curved path is called
curvilinear motion
. Example: A stone thrown into the air at an angle. Curvilinear motion describes the motion of a moving particle that conforms to a known or fixed curve.
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.
What is the acceleration of a body moving with constant speed in a circle?
A body moving at constant speed in a circular path experiences an acceleration directed towards the centre of the circular path. This acceleration is called
a centripetal acceleration
and is provided by a centripetal force. The force might be due to gravity, electro-static attraction, the tension is a string etc.
Can a body have zero velocity and still acceleration?
Answer:
Yes
, an object can have zero velocity and still be accelerating simultaneously. … While observing the object, you will find that the object will continue to move forward for some time and then stops instantly.
What is the acceleration of a freely falling body?
An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton’s second law of motion. … The acceleration is constant and equal to the gravitational acceleration g which is
9.8 meters per square second
at sea level on the Earth.
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.
What is a positive acceleration?
An object which moves in the positive direction has a positive velocity. If the object is speeding up, then
its acceleration vector is directed in the same direction as its motion
(in this case, a positive acceleration).
How do you find tangential acceleration?
The tangential acceleration
= radius of the rotation * its angular acceleration
. It is always measured in radian per second square. Its dimensional formula is [T
– 2
].
What is the constant for acceleration?
Constant acceleration refers to motion where the speed increases by the same amount each second. The most notable and important example is free fall. When an object is thrown or dropped, it experiences a constant acceleration due to gravity, which has a constant value of
approximately 10 meters per second squared
.
