A resultant force would cause...

It can be calculated by addition or subtraction for parallel forces.

For every action there is anequal and opposite reaction

Action and reaction act on different objects

The resultant forces acting upon an object isequal to the product of the mass and theacceleration of the object.

Bad effects

Good effects

Reducing friction

Depends on

is proportional to the force pressing surfacestogether

1) An object at rest would remain at rest

2) An object in motion will continue to be inmotion at a constant speed in a straight line

3) In the absence of a resultingforce acting on it

In this law, the forces are balanced
