After completion of this lesson, student must be able to:

  • Describe the uses and effects of force on objects at rest and motion.
  • Define and explain inertia of rest and inertia of motion.
  • Explain scalars and vectors.
  • Describe acceleration and retardation with example.
  • Explain the equations of motion and solve simple mathematical problems.
  • Explain Newton's Laws of motion with examples. 



Force is an external agency which changes or tends to change the state of a body from rest to motion or vice versa. When a number of forces acting on a body do not change its states of rest or uniform motion in a straight line, the force are said to be balanced forces.This note provide us further information about the force.

Inertia and Momentum

Inertia is the property of a body due to which it remains or tends to remain in the state of rest are uniform motion in a straight line unless an unbalanced forces act on it. This note provides us the information about inertia of force and different forms of inertia and momentum. Learn More

Equation of Motion of Uniform Acceleration

Equations involving displacement, initial velocity, final velocity, acceleration and time of motion of a moving body are equations of motion. This note gives us the information about equation of motion of uniform acceleration and its derivation. Learn More

Newton’s Laws of Motion

Newton’s first law states that ‘everybody continues in its state of rest or of uniform motion in a straight line unless an unbalanced force acts on it.' This notes provides an information about Newton’s laws of motion. Learn More
