Answer:
Yes, an object with constant acceleration reverses its direction of travel
. This can be explained by considering following example. Example: A body thrown to upper direction will change its direction after reaching the maximum height, but the acceleration due to gravity is always constant in this situation.
Can an object reverse?
Yes.
Direction of velocity of an object can be reversed when it’s acceleration is constant
. For example: When we throw a ball upward, it’s acceleration will be due to gravity i.e. 9.8 m/s
2
in downward direction.
Can an object with constant acceleration reverse its direction of travel can it reverse its direction twice in both cases explain your reasoning?
It is not possible to change direction twice
, given constant acceleration.
Can an object with constant velocity reverse its direction?
If the acceleration is in the direction of motion, the body will go faster. If opposite the direction of motion, it will slow down.
An object with constant velocity cannot reverse its direction
, though.
Can an object reverse its direction of travel while maintaining a constant acceleration if so given an example if not explain why?

Can an object reverse its direction while its acceleration is constant?
3 Answers.
Yes, the velocity of the object can reverse direction when its acceleration is constant.
Can a body be at rest even if it has acceleration?
Yes, A body can have acceleration while at rest
,but it will be negative acceleration or retardation.
Can the object maintains its position in the same direction while reversing the direction?
Yes, reversing the direction of acceleration will produce retardation
. Consequently, the velocity will start decreasing with time but the direction of motion will be maintained till the velocity is reduced to zero and get reversed.
Can the velocity of an object reverse direction example?
Yes.
In case of a vertically projected body, while the body is moving up, the direction of velocity is upward, whereas while it is falling down, the direction of velocity is downward
.
Can velocity change when acceleration is constant?
Yes, an object’s velocity can change direction when its acceleration is constant.
Can a body have constant speed but changing velocity?
Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.
Can an object have an eastward velocity experiencing westward acceleration?
Yes a body can have eastward velocity and westward acceleration
e.g. SHM.
Can an object change its direction of travel while maintaining a constant acceleration direction of acceleration does not change )?
Yes it is possible for an object to maintain constant acceleration and change direction
as in case of a free fall object which goes up and down changes its direction but its acceleration remains the same.
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 the velocity of an object be in a direction other than the direction of acceleration?
Yes, the velocity of an object be in a direction other than the direction of acceleration of the object.
Can the speed of a ball be zero while its acceleration is not zero?
Answer:
Yes, an object can have zero velocity and still be accelerating simultaneously
. Let us consider an object moving in the forward direction.
Can a body have mass but no weight?
Yes, a body can have a mass but no weight
. This is because the weight of the body varies from place to place with the value of acceleration due to gravity.
Can velocity be negative?
An object which moves in the negative direction has a negative velocity
. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).
Why can’t an object have a negative speed?
Speed = Distance travelled/Time taken
The ratio of distance travelled and the time taken by a body can be zero but not negative.
Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities
, speed cannot be negative.
What is the relationship between the direction of the acceleration and the direction of the velocity for an object that is moving in a straight line and slowing down?
Accelerating objects are changing their velocity – either the magnitude or the direction of the velocity. Objects moving in a circle at a constant speed are accelerating due to their changing direction.
The direction of the acceleration is directed toward the center of the circle about which the object moves
.
When velocity and acceleration are in same direction the velocity of an object?
If acceleration points in the same direction as the velocity, the object will be
speeding up
. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.
What do you mean by the term motion?
motion, in physics,
change with time of the position or orientation of a body
.
