**Constant Speed and Acceleration**
When a body is moving with constant speed, it means that its velocity is not changing. Velocity is a vector quantity that includes both magnitude (speed) and direction. Therefore, if the speed is constant, the direction of motion must also be constant.
Acceleration, on the other hand, is the rate at which an object's velocity changes. It is also a vector quantity, meaning it has both magnitude and direction. Acceleration can be caused by changes in speed, changes in direction, or both.
**The Relationship between Speed and Acceleration**
For a body moving with constant speed, the acceleration can still be nonzero. This means that even though the speed is not changing, the direction of motion can be changing. In this case, the body is undergoing centripetal acceleration, which is the acceleration towards the center of a circular path.
**Variable Acceleration**
If a body is moving with constant speed and its acceleration is nonzero, then the acceleration must be variable. This is because the body is changing its direction of motion, and the acceleration will vary as the body moves along its curved path. The magnitude of the acceleration will be greatest when the body is turning most sharply and decreases as the body enters a less curved section of the path.
**Uniform Acceleration**
In some cases, a body moving with constant speed may also have a uniform acceleration. Uniform acceleration means that the magnitude and direction of the acceleration remain constant throughout the motion. This can occur if the body is moving in a straight line and experiencing a constant force in the same direction. In such cases, the body's velocity will not change, but the acceleration remains constant.
**Conclusion**
In conclusion, if a body is moving with constant speed, its acceleration can be nonzero. The acceleration may be variable if the body is changing its direction of motion, such as moving in a curved path. On the other hand, if the body is moving in a straight line and experiencing a constant force in the same direction, the acceleration can be both nonzero and uniform.
