How is force defined in biomechanics?

  1. The amount of energy used in movement

  2. The action upon an object causing acceleration or deceleration

  3. The distance covered during an activity

  4. The overall speed of an object

The correct answer is: The action upon an object causing acceleration or deceleration

In biomechanics, force is defined as an action that causes an object to accelerate or decelerate. This is rooted in Newton's second law of motion, which states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F=ma). This definition captures the fundamental relationship between force and motion, highlighting that force is not just about movement but specifically about the changes in motion that it can induce. The other choices provided relate to different aspects of movement but do not accurately define force. Energy used in movement pertains to the work done but doesn't encompass the concept of force directly. Distance covered during an activity pertains to spatial measurement and does not involve the influence of forces. The overall speed of an object describes how fast something is moving but lacks a reference to the interactions that cause those changes in speed or direction, which is fundamentally what force does in biomechanics.
