Question

Define inertia. Describe an activity to illustrate the property of inertia of rest.​

Answer 1

Answer:

Inertia is a state of rest or in motion until applied external force.

The activity can be an example when we travel in bus or train.when start we tend to move backward and when brakes are applied we tend to fall forward.

Answer 2

Answer:

• Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed when no forces act upon them. Inertia comes from the Latin word 'iners' meaning idle, sluggish. Inertia is one of the primary manifestations of mass, which is a quantitative property of physical systems. Isaac Newton defined inertia as his first law in his Philosophiæ Naturalis Principia Mathematica, which states.

Explanation:

• Make a pile of similar carom coins on a table, as shown in the figure.

• Attempt a sharp horizontal hit at the bottom of the pile using another carom coin or the striker. If the hit is strong enough, the bottom coin moves out quickly. Once the lowest coin is removed, the inertia of the other coins makes them ‘fall’ vertically on the table.

• The inertia of coins tries to maintain its state of rest even when one of the coins moves out.
