Units - Is a smallest measure of some quantity
Fundamental Units - Length (meter) Mass (Kilogram) Time (seconds)
Derived Units - Units that are derived ( some how arrived ) from fundamental Units
Derived Units - Area , Volume, Velocity, Acceleration
Dynamics
Velocity and Acceleration
Scalar Quantity
Vector Quantity
Motion, Speed, Uniform Speed, Variable Speed, Average Speed, Displacement, Velocity, Uniform Velocity, variable velocity, Average velocity, Acceleration, Uniform acceleration,Average acceleration
Newtons Laws of Motion
Moment of a body, Impulse of a force, Inertia of a body, force,
Law 1 Every body continues in its state of rest or uniform motion in a straight line unless it is compelled to change its state by external force.
Law 2 : The rate of change of moment of a body is directly proportional to the external force acting upon it.and takes place in the direction in which the force acts.
Law 3 : To every action there is an equal and opposite reaction.
Work Power and Energy
Work - work is said to be done when the point of application of force moves W = F x S
Power - Rate of doing work Power = work done / time
Energy - energy is the capacity to do work.
Kinetic Energy - The energy of a body which depends on its motion.
Potential Energy - The energy of a body which depends on its position.
Law of Conservation of Energy - Energy can neither be created nor destroyed nor reduced. It can be changed from one form to another with same quantity or measure. The total energy is constant in the universe.
Concurrent forces and Parallel forces.
