3
Which type of friction rolling or sliding has the greater amount of friction occurring.
back
Click here for answer
What is sliding friction has more friction than rolling friction.
4
This is the formula for speed.

What is net force.
2
As the mass of an object increases …..what happens to the gravity of that object.
back
Click here for answer
The gravity increases as the mass increases.
3
