Explain the motion of a hockey puck in terms of Newton's first law

1 answer:

3 0

Newton's first law is the law of inertia stating that an object in motion stays in motion at the same speed unless acted on by an equal and opposite force and an object at rest stays at rest unless acted upon by an external force.

If a hockey puck is hit on ice (without friction), it will continue to move until friction or another force stops it. If a hockey puck is sitting in one place, the puck will not move until some external force moves it.

The motion of the hockey puck is a result of the sum of external forces on the hockey puck being unequal.

There is a need for a more sophisticated means of managing and tracking the complex movement of goods from place to place throug

saw5 [17]

The mechanism that can be used to manage and track inventory is a barcode system.

<h3>What is Inventory?</h3>

This refers to the stock-taking of goods and products in a given warehouse in order to keep records of them.

Hence, we can see that based on the need for more sophisticated means of inventory taking, we can see that the need of a barcode system is needed as tags would be given to the goods, for easier tracking.
