Not always. If a moving body changes direction without changing speed then we still say it has had an acceleration. Tie a weight to a piece of string and swing it around your head at a steady speed. The weight is accelerating towards you all the time. If the string were to break, the weight goes on in a straight line unaccelerated.
What else can I help you with?
When a body undergoes an acceleration does its speed increase or decrease?
Both. Acceleration is a change in speed.
Can there be acceleration in the body even when the body is not speeding up or slowing down?
Yes. Acceleration is change in velocity. Velocity is either change in speed or change in direction. If you fix the speed, change in direction can account for change in velocity, i.e. acceleration.
Can a body have zero velocity and still acceleration?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
How can you recognise body getting into acceleration?
a body is accelerating if it is speeding up faster and faster. Acceleration is the change in velocity. or the change in speed. Slowing down is also acceleration but it is negative acceleration or de acceleration.
A change in speed or direction?
A change in speed or direction is caused by a force and is called acceleration.
Is it possible when a body to have acceleration when moving constant speed?
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
Is it possible for a body to have acceleration if the speed is constant?
Yes. Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
Can a body have no velocity and still have acceleration?
Yes, it is possible for a body to have zero velocity but still have acceleration. This occurs when the body is changing its direction of motion, even though its speed remains constant. The acceleration in this case is due to the change in direction, not speed.
When a body move in uniform motion why and how its acceleration is constant or equal to zero?
'Acceleration' means any change in speed or direction of motion.'Uniform' motion means no change in speed or direction.
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
What does it mean for a body to have zero acceleration?
If a body has zero acceleration, it means the body is either at rest or moving at a constant velocity in a straight line. This implies that there is no change in its speed or direction over time.
Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
