Define inertia and explain the three types with two examples each
Answers
Three types of inertia are:
1). Inertia of rest: The ability of a body to resist any change in its state of rest.
2). Inertia of motion: The ability of a body to resist any change in its state of motion.
3). Inertia of rotation/direction: The ability of a body to resist any change in its state of rotation (or direction) is inertia of rotation.
examples -
Inertia of rest: when the bus starts and moves forward we are pushed backward
Inertia of motion: when a moving bus stops suddenly we fall forwards
Inertia of direction: when the bus suddenly takes turn we fall in the direction opposite to it.
Answer:
The tendency of bodies to remain in their state of rest or uniform motion along a straight line in the absence of any external force is called inertia.
