admin Work is the transfer of energy when a force acts on an object over a distance. Energy is the capacity to perform work, existing in various forms such as kinetic, potential, and thermal, crucial in physical processes. Physics Class 11 Chapter 4 Notes The conservation of energy is written as: Total energy = K.E + … Read more
Motion refers to the change in position of an object over time, while force is a push or pull that causes or changes the motion of an object. Together, they are fundamental concepts in physics, describing how objects move and interact. Physics Class 11 Chapter 3 Notes For which pair ranges of projectile are same: … Read more
Vectors are quantities with both magnitude and direction, used to represent forces and motion. Equilibrium occurs when the sum of forces and moments acting on an object is zero, leading to a state of balance in physics. Physics Class 11 Chapter 2 Notes Important : Review all previous years’ 11 Class Past Papers for comprehensive … Read more
