Form 5

Resultant force

The single force that represent the vector sum of two or more forces acting on an object

Free body diagram

Diagram that show all the forces acting on abject only

Resolution of forces

Process of revolving a force into two components

Equilibrium of forces

Forces acting on it produce a zero resultant force

Elasticity

Property of material that enables an object to return to its original shape and size after the force applied is removed

Hookes law

The extension of a spring is directly proportional to the force applied on the spring provided the elastic limit of the spring is not exceeded
