|
if there is a constant velocity, will there be acceleration?
|
NO
|
|
|
if there is no acceleration, will there be a net force?
|
NO
|
|

surface area has __ effect on frictional force
|
NO
|
|
|

|
|
|
Which is greater... static frictional force or the kinetic frictional force?
|
Static frictional force

|
|
What is the relationship between mass of an object and the force needed to keep it moving at a constant rate?
