A student attached a spring balance to a block of wood and gently pulled it outwards. She found that a force of 120 gf is needed to just slide the block. However, as the block slides, the spring balance registers a force of 100 gf. This means that the force of 120 gf and 100 gf are respectively _______ and________.
(a) static friction, limiting friction (b) limiting friction, sliding friction
(c) sliding friction, limiting friction (d) static friction, sliding friction

Answer 1

Answer:

I Think C) Sliding And Limiting Friction Is The Answer...
