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 ...

  Activity: To Study the Variation of Potential Drop Along a Uniform Wire Using a Potentiometer Aim To study the variation of potential drop with length of a uniform wire and hence verify the principle of a potentiometer. Apparatus Required Potentiometer, driver cell (battery), rheostat, galvanometer, jockey, given cell, key, voltmeter (optional), connecting wires. Principle A potentiometer works on the principle that the potential drop across a uniform wire carrying steady current is directly proportional to its length . Mathematically: V ∝ l or V = k l where: V = potential drop l = length of wire k = potential gradient (potential drop per unit length) Theory When a steady current flows through a uniform potentiometer wire, the potential drop along the wire is uniform. Using the null deflection method, the potential difference across a cell can be measured accurately without drawing any current from it. This ensures high accuracy. The principle is verified by showing that the rati...
