Sum of forces in any one direction is zero c) A block of known mass, M is placed on a flat table and connected to a scale pan using a light string. A weight is placed on the scale pan and block given a slight push. More weights are added, block given a slight push until the block slides with uniform velocity. Weight of scale pan and contents is obtained. Experiment is repeated for blocks of different masses. A graph of weight scale pan and content against weight of block is plotted. The slope is calculated. The co efficient of kinetic friction, NR = S, [Y] = d) When a body in stable equilibrium is titled, its c.o.g is raised and on release it returns to the original position. When a body in unstable equilibrium is titled slightly, its c.o.g is lowered, P.E is reduced and on release, it falls down. 1 [A] [e] = SET ONE PRE REGISTRATION EXAMINATIONS 2024 2 Fe ; e = ∝𝒾∆ 𝜃 A.e e. i) Y = 1 Uganda Advanced Certificate of Education MLT−1L 2 x 640 x 7.68 x 10-6 ; e = 1.6x10-7 x 0.6 x 80 ∴ E = 2.46 x 10-3 J PHYSICS P510/1 MARKING GUIDE 2 a i) Inertia is the reluctance of a body to start moving when at rest or to stop moving when in motion. = L2 L ii) Is a point where the resultant gravitational f
