why is it harder to maintain costant accleration rather than cosntant velocity when walking

When walking, it is generally easier to maintain a constant velocity compared to maintaining constant acceleration. This is because acceleration involves a change in velocity over time, while velocity refers to the speed and direction of an object's motion.

To understand why it is harder to maintain constant acceleration while walking, we need to examine the factors affecting acceleration:

1. Muscle contractions: When you walk, your muscles contract and relax to generate the necessary force for movement. Maintaining a constant acceleration requires continuous adjustments in muscle contractions to generate the appropriate force at different moments. This requires coordination and precision.

2. External forces: Walking involves interacting with various external forces, such as friction between your feet and the ground, air resistance, and the gravitational force pulling you downward. These forces can alter your acceleration and require continuous adjustments to maintain a constant acceleration.

On the other hand, maintaining constant velocity while walking is comparatively easier due to the following reasons:

1. Natural stride: When walking at a constant velocity, your body naturally settles into a comfortable rhythm and stride length. This reduces the need for constant adjustments and precision in muscle contractions.

2. Balance: Walking at a constant velocity is influenced by your body's natural ability to maintain balance. Once you find a steady pace, your body adapts to it, minimizing the need for continuous corrections.

In summary, maintaining constant acceleration while walking is more challenging than maintaining constant velocity due to the continuous adjustments needed in muscle contractions and the influence of external forces.
