What we have learnt

  • The historical evolution of motion theory from Aristotle to Newton laid the groundwork for modern physics.
  • Newton’s three laws of motion provide a framework for understanding the effects of forces on the movement of objects.
  • The ability to distinguish between scalar and vector quantities is crucial for accurate motion analysis.

Key Concepts

-- Force
A vector quantity representing an interaction that can change an object's motion, measured in newtons (N).
-- Mass
A scalar quantity indicating the amount of matter in an object, related to inertia and measured in kilograms (kg).
-- Inertia
The tendency of an object to resist changes in its state of motion, fundamentally linked to mass.
-- Newton's Second Law
States that acceleration is directly proportional to net force and inversely proportional to mass, expressed as F = m × a.
-- Scalar and Vector Quantities
Scalars have magnitude only, while vectors have both magnitude and direction.
