Why does a rough surface cause greater friction to an object moving across it than a smooth surface?
What is THERE IS MORE SURFACE AREA IN A ROUGH SURFACE SO THE ROUGH SUFACE GRABS HOLD OF THE OBJECT AND DOESN'T ALLOW IT TO SLIDE AS EASILY.

How can the speed of an object describe its velocity?
What is ADD THE OBJECT'S DIRECTION
400
How is acceleration related to velocity?
What is ACCELERATION IS A CHANGE IN AN OBJECTS SPEED OR DIRECTION. SINCE VELOCITY DESCRIBES AN OBJECTS SPEED AND DIRECTION, ACCELERATION IS A CHANGE IN VELOCITY.
