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.

<h3>What are the species of butterflies?</h3>

Butterflies usually are identified by the colors and patterns shown on their wings. However, for us to identify an organism using a dichotomous key, we must compare the traits of the organism to the first pair of descriptive statements on the key as follows;

1) A swallowtail butterfly is either classified as Papilio glaucus ( where the wings are mainly yellow) or Papilio polyxenes(where the wings are mainly black)

Now, the image of the butterfly given shows that the wings are mainly black, and as a result, we will say that the butterfly specie is called Papilio Polyxenes.
