Solution
The type of friction that has to be overcome to put an object into motion is D. static friction.
Here's why:
-
Static friction is the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest.
-
It must be overcome to start moving the object. If you've ever tried to push a heavy object like a piece of furniture, you've felt static friction in action.
-
Once the object is in motion, it then experiences sliding friction (also known as kinetic friction).
-
Rolling friction and fluid friction are not typically involved in simply putting an object into motion from a standstill on a solid surface. Rolling friction occurs when an object rolls over a surface, and fluid friction occurs when an object moves through a fluid or when a fluid moves past an object.
So, the answer is D. static friction.
