Precautions during physics practical ~ Avoid parallax error by placing the eye such that the line of view is perpendicular to the scale of the ruler. Students are advised to perform their experiments under safety care. Primary science coordinators should consider these in the production of their own safety rules for practical work in their school classrooms. Precautions for ALL experiments.
Use lids where possible to reduce heat loss by convection. Boards and strings are frequently used and if they. 7162016 Avoid heat transfer by convection by switching off the fans and closing windows and doors. Dont perform experiments at home if they have been forbidden by your teacher.
Spring return to original length when load is taken off. It is an essential property of fluids which describes a liquids confrontation to flow and is related to the inner friction within the fluid. Points should be marked only when weights are at rest. It carries a total of 30 marks.
Make sure the spring is not loaded beyond the elastic limit. Weights may not be accurate. The pulleys should be frictionless. Safety goggles should be worn due to the chance of an object accelerating into someones face.
So students must perform their Class 11 Physics practical exams diligently to perform better in the final exam. Gain a mastery of essential scientific skills. Experiments should be very structured and organized when it comes to the final physics practical class 12 examination when it comes to scoring high. A geometrical set with set-squares and protractor O level entry proof.
