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...
SOME SOLVED PROBLEMS ON SPEED VELOCITY AND ACCELERATION Hello students in this article I have posted few solved problems on Speed, Velocity and Acceleration. Example#01: A sprinter completes its 100 meters race in 12 sec. Find its average speed. Solution: From the given data we have; distance = 100 meters Time taken = 12 seconds Average speed=? As we know that Avg. speed= distance travelled/time taken ...
