Which of the following is the correct relationship?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. F = ma.
The correct relationship is F = ma, which is Newton's Second Law of Motion. It states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). This fundamental equation in physics describes how the velocity of an object changes when a force is applied. The law is crucial in understanding the motion of objects and is used extensively in mechanics to calculate forces and predict the behaviour of objects under various conditions.
