 LAW OF MOMENTS

Aim To determine the mass of a given body using a meter scale by principle of moments.

Apparatus A meter scale suspended at C.G., hanger with slotted weights, a body of unknown mass.

Diagram:

Mean mass=70 g

Result  The unknown mass of a body m1 = 70 g

PHYSICS11  Chapter No 4.Laws O f Motion Newton's first law: Statement every inanimate object continuous to be in a state of rest or of uniform uniform motion along a straight line unless it is acted upon by an external unbalance force. Newton second law: statement The rate of change of linear momentum of a rigid body is directly proportional to the applied (external unbalanced) force and takes place in the direction of force. Newton's third law statement To every action there is always an equal and opposite reaction. Inertial frame of reference Inertial frame of reference is a frame of reference in which Newton's laws of motion are verified. Non inertial frame of reference A frame of reference in which Newton's laws of motion are not verified. Kinematics In Which motion describe without it's cause. Dynamics In Which motion describe along with its cause. Contact force The force experienced by a body due to Physical contact is called contact force. Non contact ...
