when a body body free fall from a height then its acceleration is negative or positive?
Verified Answer

If an object is slowing down, then its acceleration is in the opposite direction of its motion. This general principle can be applied to determine whether the sign of the acceleration of an object is positive or negative, right or left, up or down, etc.

A negative velocity means that the body is moving in the negative direction of the y axis—that is, downward. This is true no matter where the body is located. We take the acceleration to be negative (-9.8 m/s2) in all problems dealing with falling bodies

Acceleration of a Body in Free Fall

When a body falls freely from a height, its acceleration is negative. This is because the acceleration due to gravity always acts in the downward direction, towards the center of the Earth.

Explanation
- The acceleration due to gravity is denoted by the symbol 'g' and its value is approximately 9.8 m/s^2 on the surface of the Earth.
- As the body falls freely, the only force acting on it is the force of gravity, which causes the body to accelerate towards the Earth.
- Since the acceleration is in the downward direction, it is considered negative in the context of motion in a straight line.
- The negative sign indicates that the acceleration is in the opposite direction to the positive direction of motion (i.e., downwards in the case of free fall).

Sign Convention
- In physics, the convention is to consider downward motion as negative and upward motion as positive.
- Therefore, when a body falls freely from a height, its acceleration is negative due to the downward direction of the force of gravity.

Conclusion
In conclusion, when a body is in free fall, its acceleration is negative as it is directed towards the center of the Earth. This negative acceleration due to gravity causes the body to accelerate downward as it falls.
