Question

Mass and Inertia (2)

Not quite remember

I easily remember

Example of inertia (2)

- When the train moves, the passenger will move forward together with the train - When the trains stop suddenly, the body of the passenger maintains its forward motion

Example of inertia (3)

-When the train stops suddenly, the body of the passenger maintain in its forward motion - Inertia of the passenger maintains the original state of passenger, that is being in motion

Relationship between mass and inertia (1)

The inertia of an object is affected by its mass

Relationship between mass and inertia (2)

The larger the mass of an object, the larger the inertia of an object

Situations showing relationship between mass and inertia (1)

- The mass of an empty trolly is small, therefore the inertia of the trolley is also small - This enables the trolley to be easily moved from its original state

Situations showing relationship between mass and inertia (2)

- The mass of the trolley filled with things is larger - Therefore its inertia is also larger - The trolley is more difficult to move

Tool to study the relationship between mass and inertia

Inertial balance

The party that created the inertia balance

Postive effects of inertia (1)

The loose head of hammer can be tightened by banging its handle against a hard surface

Positive effects of inertia (2)

A wet umbrella can be dried by spinning the umbrella quickly and stopping it suddenly
