HOOKE'S LAW Introduction In physics, Hooke's Law is one of the fundamental principles governing how objects deform under external forces . Named after the 17th-century British physicist Robert Hooke, this law provides a crucial understanding of the behavior of elastic materials, such as springs and rubber bands. Whether stretching a rubber band or compressing a spring, Hooke's Law helps explain what happens when forces act on these materials. What is Hooke's Law: Hooke's Law states that the force F needed to extend or compress a spring by some distance x is proportional to that distance. Mathematically, it is expressed as: F= -kx Here k represents the spring constant, which is the measure of the stiffness of the spring, and x is the displacement from the displacement position. The negative sign indicates that the force exerted by the spring is in the opposite direction of the displacement. Understanding the Spring Constant: The spring constant k is a critical co
Centripetal Force A force that compels a body to move in the circular path is termed as Centripetal Force. It is denoted by Fc. Derivation: Centripetal Force is directly proportional to the mass of the moving body. Centripetal force is directly proportional to the square of the velocity. Centripetal force is inversly proportional to the radius of the circular path. Centripetal Acceleration The acceleration produced due to the centripetal force is known as Centripetal Acceleration. It is denoted by ac. Derivation:
