  • 3.1

    Introduction

    This section introduces the significance of motion and the influence of forces, primarily governed by Newton’s Laws of Motion.

    Learning Practice

  • 3.2

    Force

    Force is defined as a push or pull that alters the motion or rest of a body.

  • 3.3

    Newton’s Laws Of Motion

    Newton’s Laws of Motion describe the relationship between the motion of an object and the forces acting on it.

    Learning Practice

  • 3.3.1

    First Law (Law Of Inertia)

    The First Law of Motion, or Law of Inertia, states that an object remains at rest or in motion unless acted upon by an external force.

    Learning Practice

  • 3.3.2

    Second Law (Law Of Acceleration)

    The Second Law of Motion states that the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass.

    Learning Practice

  • 3.3.3

    Third Law (Action-Reaction Law)

    The Third Law of Motion states that every action has an equal and opposite reaction, emphasizing the interaction between forces.

  • 3.4

    Inertia And Its Types

    Inertia refers to the property of an object to resist changes in its state of motion or rest.

    Learning Practice

  • 3.4.1

    Inertia Of Rest

    The inertia of rest describes a body’s tendency to stay at rest unless acted upon by an external force.

    Learning Practice

  • 3.4.2

    Inertia Of Motion

    Inertia of motion describes how a body continues to move in a straight line at a constant speed unless acted upon by an external force.

    Learning Practice

  • 3.4.3

    Inertia Of Direction

    The inertia of direction describes the tendency of a body to maintain its direction of motion unless acted upon by an external force.

    Learning Practice

  • 3.5

    Momentum

    Momentum is the product of mass and velocity, representing the quantity of motion an object possesses.

    Learning Practice

  • 3.6

    Impulse

    Impulse is the product of force and time, which results in a change in momentum.
