Newton's Third Law of Motion
For every action there is an equal and opposite reacion.
Force
Vector Quantity.
has both magnitude and direction
push and pull of an object.
F = ma
Weight
a force exerted on a body under gravitational field.
Vector Quantity
depends on where it is measured due to the gravitational force
same direction as acceleration due to gravity and directed to the centre of Earth.
S.I. Unit: Newton (N)
Newton's First Law of Motion
Law of Inertia
Mass
measure of the initial property of the object of the amount of matter it contains.
mass will be the same at any place
Scalar Quantity
S.I. Unit: Kilograms (kg)
