|
the object is speeding up
|
|
|
the object is slowing down
|
|
|
the object is moving at constant speed
|
|
|
the object is changing direction
|
Detailed explanation-1: -If an objects acceleration is zero, then its speed must remain constant.
Detailed explanation-2: -If an objects acceleration is zero, then its speed must remain constant.
Detailed explanation-3: -Which statement best describes the movement of an object with zero acceleration? The object must be at rest.
Detailed explanation-4: -Explanation: If an object is moving with constant velocity, then its acceleration must be zero. We can then look at Newton’s second law. If the acceleration is zero, then the net force must also be zero.
Detailed explanation-5: -(c) True. When a particle moves with a constant speed in the same direction, neither the magnitude nor the direction of velocity changes and so acceleration is zero.
