  3. FORCE It is a push or pull which either changes or tends to change the state of rest or of uniform motion of a body.
  4. INERTIA In the absence of external force, the inability of a body to change its state by itself is called INERTIA.
  5. NEWTON’S FIRST LAW OF MOTIONor LAW OF INERTIA It states that every body continues in its state of rest or of uniform motion in a straight line , unless it is compelled by some external force to change that state.
  6. NEWTON’S SECOND LAW OF MOTION The rate of change of momentum of a body is directly proportional to the applied force and change takes place in the direction of applied force. F = ma
  7. NEWTONS THIRD LAW OF MOTION According to Newton third law of motion , it states that to every action their is equal and opposite reaction. F’ = - F”
  8. VECTORS Those physical quantities which need magnitude as well as direction for there complete representation is called a vector quantity.
  9. Laws of vector addition Triangle law of vector addition Parallelogram law of vector addition
  10. Triangle law of vector addition Let two vectors P and Q be represented both in magnitude and direction by sides AB and BC of triangle ABC taken in same order, Then, Acco. To triangle law, the resultant R is given by the closing side AC taken in opposite order. Here in triangle ADC AC= AD + CD R= (AB+BD) + CD R = AB + BD + 2AB.BD + CD R = P +BC +2.AB.BD R= P + Q 2P.Q Cos0 R= P + Q + 2PQ Cos0 c R Q B D A B
