ICSE Class 10 Physics — Chapter Summary

Force is a push or pull applied on a body by another body to change its state, size, or shape. It can change motion, stop motion, start motion, or deform an object. Force is measured in newton in the SI system and dyne in the CGS system. Force is the basic idea behind motion, turning effect, equilib

Work is done only when a force acts on a body and the body is displaced. Work, energy, and power are closely connected ideas in physics. Work measures the effect of a force through displacement, energy is the capacity to do work, and power is the rate at which work is done. The chapter also explains

Machines are devices that help overcome a large resistive force by applying a smaller force at a convenient point and in a desired direction, or by giving gain in speed. A machine may act as a force multiplier, speed multiplier, or simply change the direction of effort. The chapter covers the main i
