This is in accordance with Newton’s first law which states that a body moving in a straight line continues to move in a straight line unless acted by an external force. Passengers swinging in a turning bus: Whenever a bus turns sharply, we can feel ourselves moving in the opposite direction.
Let us discuss each of the examples and see how they are consistent with Newton’s first law of motion. The resistance to this external force is called inertia. An external force is necessary for causing a change in speed, direction, or state of motion. This law shows that all objects have a tendency to maintain their original state of motion. Newton’s first law statementĪn object in rest or uniform motion in a straight will continue to be in rest or uniform motion unless and until acted upon by an external force.
Example of newton’s first law: The change in direction, speed, and state of motion by external forces (muscular force and frictional force).
