Question

The law of acceleration is also known as:

• A. Law of inertia
• B. Law of action & reaction
• C. Law of Resultant Force
• D. Boyle’s Law

Answer 1

The Correct Option is C

The law of acceleration is also known as the "Law of Resultant Force." In physical education, this principle is essential for understanding how forces affect the movement of objects and individuals. The law is one of Newton's three laws of motion and can be stated as follows: 

Explanation: Newton's Second Law of Motion, often referred to as the Law of Resultant Force, 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 is expressed mathematically as F = ma, where F is the force applied, m is the mass, and a is the acceleration.

This law is crucial in many practical applications, such as calculating the amount of force needed to move a player in sports or determining the impact forces during collisions in activities like football or martial arts.

Options Analysis:

Law of inertia: This refers to Newton's First Law of Motion.

Law of action & reaction: This is another name for Newton's Third Law of Motion.

Boyle’s Law: This pertains to the gas laws and is unrelated to motion.

Law of Resultant Force: Correct, as explained above.

Answer 2

Newton’s second law, also known as the law of acceleration, is one of the fundamental principles of classical mechanics. It states that the acceleration of an object is directly proportional to the resultant force acting on the object and inversely proportional to its mass. The mathematical representation of this law is given by the formula:

F = ma

Where:

• F is the resultant force applied to the object,
• m is the mass of the object,
• a is the acceleration produced by the force.

This law implies that a greater force is needed to accelerate an object with a larger mass at the same rate, and conversely, a smaller force will result in greater acceleration for a lighter object. It is a crucial principle in understanding how objects move and how forces interact with matter in the physical world.

In conclusion, Newton’s second law, or the law of acceleration, explains the relationship between force, mass, and acceleration, providing a foundation for understanding motion in classical mechanics.
