What is defined as the change in motion or shape of a body?

• A. Momentum
• B. Velocity
• C. Force
• D. Acceleration

Answer: (C)

The change in motion or shape of a body is best described by force. Force is defined as an interaction that causes an object to undergo a change in motion, which can include altering its speed or direction, and in some cases can cause deformation (a change in shape). When you apply a force to an object, it leads to a change in velocity according to Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. This relationship establishes that force is responsible for causing any motion or shapes alterations. While momentum, velocity, and acceleration are related concepts in mechanics, they do not entirely encapsulate the concept of causing change in motion or shape. Momentum is a measure of the quantity of motion an object has, velocity pertains to the speed and direction of an object's movement, and acceleration specifically describes the rate of change of velocity. None of these terms directly address the cause of that change, which is where the role of force comes into play.
