The tangential force acting on an object that opposes it from sliding freely on the adjacent surface is called
A
Weight
B
Upthrust
C
Frictional force
D
Normal force
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Frictional force is the tangential force opposing an object's free sliding on an adjacent surface. It originates from surface irregularities and intermolecular attractions between materials, resisting relative motion or its initiation.
