What is rolling friction?
Answer
-
When round objects roll across a flat floor and both the object and floor are bent slightly out of shape.
-
Air resistance acted on in both gases and liquids.
-
A force that acts on objects that are NOT MOVING and is ALWAYS OPPOSING movement

Question 22
Question
How do sprinklers apply Newton's 3rd law of Motion? Choose the BEST answer.
Answer
-
The greater the mass of the sprinkler, the harder it is for the sprinkler to turn.
-
The sprinkler stays in motion unless you turn it off to make it at rest.
-
Sprinklers spray out water, causing the sprinkler to move in the opposite direction in the shape of a circle.
-
The lesser the mass of the sprinkler, the harder it is for the sprinkler to turn.
