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.

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

friction occurs because no surface is perfectly smooth.

I really hope this helps otherwise imma look like a complete idiot

i think so it’s will be b yes i believe its

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
