An experiment was done using a spring scale attached to a 1.00 kg wooden block on a horizontal surface. The force applied on the block through the scale was gradually increased until the block started to move, at which point the applied force decreased. The following data was collected: Applied force (N) Frictional force (N) Block 1.00 kg 2.0 2.0 Spring scale 3.0 3.0 4.0 4.0 3.5 3.5 3.5 3.5 An experiment was done using a spring scale attached to a 1.00 kg wooden block on a horizontal surface.
