Questions and Answers

According to the law of gravitation, the force of attraction between two objects is proportional to:

  • The sum of their masses
  • The square of the distance between them (correct)
  • The square root of their masses
  • The cube of the distance between them

    • The force of gravity decreases with altitude because:

  • There is less mass at higher altitudes
  • The acceleration due to gravity decreases
  • The distance from the center of the Earth increases (correct)
  • There is more air resistance at higher altitudes

    • The weight of an object is equal to the product of its:

  • Mass and acceleration due to gravity (correct)
  • Mass and volume
  • Density and acceleration due to gravity
  • Volume and density

    Study Notes

    Law of Gravitation

    • The force of attraction between two objects is directly proportional to the product of their masses.
    • This means that as either mass increases, the gravitational force increases.

    Force of Gravity and Altitude

    • The force of gravity decreases with altitude due to the increase in distance from the Earth's center.
    • At higher altitudes, the gravitational pull diminishes as the distance increases, leading to reduced gravitational force.

    Weight of an Object

    • The weight of an object is equal to the product of its mass and the acceleration due to gravity (W = mg).
    • Weight is a force measured in newtons and varies depending on the gravitational field strength.

    Immersion in Fluids

    • When an object is immersed in a fluid with a density less than its own, it will float or remain suspended.
    • This principle relates to buoyancy, where the upward buoyant force is less than the object's weight.

    Variation of Gravitational Force on Earth's Surface

    • The force of gravitation varies slightly across the Earth's surface due to its shape and rotation.
    • Gravitational force is stronger at the poles compared to the equator because of the Earth's oblateness and the effects of centrifugal force.
