Resultant Force

Two forces of the same magnitude in opposite directions applied on a stationary object

Object remains at rest

Two opposing forces have different magnitudes

Object will move in the direction of the larger force

Resultant Force

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

Practical means to determine magnited and direction of two forces that are at an angle with each other

Free body diagram of an object

Diagram that shows all the forces acting on that object only

Object in a stationary state

Weight, W=Normal reaction, R

Object moving with a uniform velocity

Engine thrust, T=Frictional force, Fr

Object moving with a uniform acceleration

Resultant force=T-Fr
