Question

what is the property of inertia​

Answer 1

Inertia

Inertia is the property of a body to keep its position, motion and direction unchanged until an external unbalanced force is applied on it.

Galileo's Law of Inertia

A body moving with a certain speed along a straight path will continue to move with same speed along the same straight path in the absence of external forces.

Inertia is of 3 types-

• Inertia of Rest

If a body is in rest, then it will remain in rest until an external force is applied on it.

• Inertia of Motion

If a body is in motion, then it will remain in motion until an external force is applied on it.

• Inertia of Direction

The tendency of a body to change by itself its direction of motion is called of inertia of direction.

Examples of Inertia

• A glass is broken into pieces when a stone strikes on it, but when a high speed bullet hits the glass it makes a clean hole.
• The persons sitting in the bus falls backward when bus suddenly starts.
• An athlete runs very fast before taking high jump.
• A man getting down of a moving bus falls forward.
• The dust particles fall off from a woollen blanket when it is beaten by a stick.

Answer 2

Explanation:

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. ... The mass of an object can be measured by observing the extent of its inertia.
