Gravity, weight and mass

Gravity, weight and mass

  • Gravity is a force that attracts everything in the universe.

  • The earth and the sun are attracted by more stronger force of gravity.

  • The more massive objects have high gravity.

  • Gravity between two objects becomes weaker as the objects move further apart.

  • High and low tides in the ocean are because of the moon's gravity.

  • gravitational field strength is measured in newtons per kilogram (N/kg).

  • Weight is measured in newtons.

  • Weight can change according to the location.

  • Mass is measured in kilogram.

  • Mass can't be zero.

  • The mass of an object always stays same, even when an object's location changes.

  • Mass is not affected by gravity.
