3. Laws of Motion

The chapter outlines the fundamental Laws of Motion established by Sir Isaac Newton, which describe the relationship between motion and the forces acting upon objects. Key concepts include the distinction between balanced and unbalanced forces, Newton's three laws, the role of friction, and the differences between mass and weight. Furthermore, the chapter discusses the implications of these laws in real-world applications, demonstrating their relevance in everyday scenarios.

    Introduction To Laws Of Motion

    This section introduces the Laws of Motion formulated by Sir Isaac Newton, outlining their significance and the fundamental relationship between motion and forces.

    Learning Practice

  • 3.2

    Force

    Force is a push or pull acting on an object that can change its motion or shape.

    Learning Practice

  • 3.3

    Balanced And Unbalanced Forces

    This section discusses balanced and unbalanced forces, highlighting their definitions and implications for an object's motion.

    Learning Practice

  • 3.4

    Newton’s First Law Of Motion (Law Of Inertia)

    Newton's First Law states that an object at rest will stay at rest, and an object in motion will remain in motion unless acted upon by an external force.

    Learning Practice

  • 3.5

    Newton’s Second Law Of Motion

    Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass.

    Learning Practice

  • 3.6

    Newton’s Third Law Of Motion

    Newton’s Third Law states that for every action, there is an equal and opposite reaction.

    Learning Practice

  • 3.7

    Friction As A Force

    Friction is a force that opposes the motion of an object and can be beneficial or detrimental depending on the situation.

    Learning Practice

  • 3.8

    Mass And Weight

    Mass is the measure of matter in an object, while weight is the force with which gravity pulls on that mass.

    Learning Practice

  • 3.9

    Momentum

    Momentum refers to the quantity of motion possessed by a body, calculated as the product of its mass and velocity.
