LAWS OF MOTION
LAW OF INERTIA
LAW OF ACCELERATION
LAW OF INTERACTION
IMPORTANCE
They form the most intuitively appealing physical theory.
They represent mankind’s first great success at describing diverse aspects of nature with simple mathematical formulas.
These laws actually work.
They lay the groundwork for later physics developments.
REAL LIFE EXAMPLES
Law of inertia: A body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it.
RIDING A BUS
Law of Acceleration: The net force experienced by a body is directly proportional to the rate of change of momentum of the body. It can be written as given below,
F = ma
TWO OBJECTS WITH DIFFERENT MASS
Law of Interaction: for every action, there is an equal and opposite reaction.
