For example, if a mobile phone is kept somewhere on a tabletop, it will remain there until someone else picks it up or displaces it. Inertia is a property of a body by which it resists any force applied to it. This law of inertia was later used by Newton, who said, “If a body is in a state of motion, it keeps moving in the same direction, and if it is in a state of rest, it remains in a state of rest until an external force is applied on it.” This is known as Newton’s first law of motion. InertiaĪccording to the inertia, or Galileo’s law of inertia, a body in a state of rest continues to be in a state of rest, and a body in a state of motion continues to be so until an external force is applied to it. This concept was objected to by Galileo, who found out through his experiments that a body can keep moving even without applying an external force on it. These observations supported that force was required to keep a body moving. They thought that a body stops as soon as the force applied to it is withdrawn.įor example, if we are rowing a boat, it keeps moving in water, but the boat stops moving forward as soon as we stop rowing. Before Galileo Galilei found the concept of the moment of inertia, scientists believed that an external force is required to move a body, keep it in motion, and stop a body. ![]()
