  • Statics

    deals with effect of force on bodies which are not moving

    Dynamics

    deals with force effect on moving bodies

    We will be studying the effect of force on objects (rigid-

    bodies) in this subject.

    So, Why is it important to study the effect of

    forces on objects?

  • Why do objects move as they do?

    Why do objects remain in rest as they do?

    Newtons Laws

    What happening when the Dad pushes the swing forward once?

    What are the action of forces we can identify around us?......Think!

  • 1st Law 1: An object persists to be in its original state unless acted upon by an external force.

    2nd Law: The acceleration of a body is directly proportional to the net applied force. F = ma.

    3rd Law: Every action has an equal and opposite reaction.

    Dimensional Homogeneity:

    Always use consistent units. Each term used in a physical process must be expressed in the same units.

    Units to be used:

  • Some points to note when using SI units:

    No Plurals (e.g., m = 5 kg not kgs )~might be confused with second(s)

    Separate Units with a dot (e.g., meter second=m s )

    Most symbols are in lowercase ( some exception are N, Pa, M and G)

    Exponential powers apply to units , e.g., cm2 = cm cm

    Three of the kinetic units, referred to as basic units,

    may be defined arbitrarily. The fourth unit, referred to

    as a derived unit, must have a definition compatible

    with Newtons 2nd Law,amF r

    MURPHY's Laws

    1. Nothing is as easy as it looks.2. Everything takes longer than you think.3. Anything that can go wrong will go wrong.4. If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong. Corollary: If there is a worse time for somethingto go wrong, it will happen then.5. If anything simply cannot go wrong, it will anyway.6. If you perceive that there are four possible ways in which a procedure can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.7. Left to themselves, things tend to go from b
