Force is a crucial concept in physics, defined as a push or pull that can alter the state of motion or shape of an object. It can result in acceleration, deceleration, or change of direction. The chapter covers various types of forces, the principle of moments, equilibrium, and mechanical advantages of machines, providing essential knowledge for understanding physical interactions and simple machines.
A force can change the speed, direction, or shape of an object.
Resultant force is the single force equivalent to multiple forces acting on a body.
The principle of moments states that for equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments.
A physical cause that can change the state of motion or shape of a body.
The single force that produces the same effect as multiple forces acting on a body.
The turning effect of a force about a point or axis, calculated as Moment = Force × Perpendicular distance from pivot.
A state in which a body experiences no net force, meaning the resultant force acting on it is zero.
The ratio of the load to the effort applied in a machine.
The ratio of useful work done by a machine to the total energy expended, expressed as a percentage.
