Question

Veronica observes how the force of friction causes an object to slow down. She writes the following observation: When an object moves across a smooth surface, there is less friction created than when an object moves across a rough surface. When the object stops moving, friction is created. Which statement corrects the error(s) in Veronica's observations?

It is not smooth or rough surfaces that affects friction. It is the size of the push.


When an object moves across a rough surface, there is no friction.


When an object moves across a smooth surface, the friction increases.


When an object stops moving, there is no friction.

Answer 1

Answer:

that explanation was true and false at the same time because if there is no friction then there is no pull

Explanation:

Answer 2

The correct answer is as follows:

When an object stops moving, there is no friction.

• Friction is created when an object starts moving on a surface.
• Veronica's conclusions regarding less friction on a smooth surface and more friction on a rough surface were correct.
• However, she said that friction is created when an object stops moving, which is wrong. Friction cannot be produced if an article is static.
