  • A force is an external agency (push or pull)
    which changes the state of rest or of uniform
    motion of a body.
  • (i) Produces motion in a body at rest, (ii) Stops
    or tries to stop a moving body, or (iii) changes
    or tries to change the direction of motion of the
    body.
  • Newton's first law states that every object will
    remain at rest or in uniform motion in a straight
    line unless compelled to change its state by the
    action of an external force.
  • Newton's second law of motion states that the
    rate of change of momentum is equal to the force
    acting on the particle.
  • Force ? rate of change of momentum
  • ? rate of change of (mass velocity)
  • Force ? mass rate of change of velocity
  • ? mass acceleration
  • F ? ma

  • A force system is a collection of forces acting
    at specified locations in one or more planes.
  • When two or more forces act on a body, they are
    called for a system of force.
  • Concurrent / Non-concurrent Point
  • Coplanar / Non-coplanar Plane
  • Collinear/ Non-collinear Linear
  • Parallel/ Non-Parallel llel or Not

Concurrent forces The forces, which meet at one
point.

  • Non-concurrent Forces The forces, which act at
    different points.
  • Coplanar forces The forces, whose lines of
    action lie on the same plane.
  • Non-coplanar Forces The forces, whose lines of
    action lie on the different plane.

Collinear forces The forces acting along the
same line of action. Non-collinear
forces The forces acting along the different
lines of action.

Parallel Forces The forces line of action are
parallel to each other is called parallel forces.
