How do I prepare for practical Viva?

Create a good impression: Appear neatly and decently dressed. Wish him with a confident smile and ask him if you can take the seat. Display respect and good attitude towards the examiner. Never give prepared speech as an answer to question; try to be short and to the point.

What is practical of physics?

Practical Physics is a collection of experiments that demonstrate a wide range of physical concepts and processes. These resources are for the use of teachers of physics in schools and colleges. Some of the experiments can be used as starting-points for investigations or for enhancement activities.

How do I study for practical board exam?

1. Be good with diagrams and circuits. Visualize and draw rough diagrams for the experiments to prepare.
2. Be confident during the practical examination. A student should be confident about whatever topic is given by the examiner.
3. Sharpen your senses.

What are the 3 types of experimental errors?

Three general types of errors occur in lab measurements: random error, systematic error, and gross errors. Random (or indeterminate) errors are caused by uncontrollable fluctuations in variables that affect experimental results.

What are 3 sources of error in an experiment?

Physical and chemical laboratory experiments include three primary sources of error: systematic error, random error and human error.

How do you reduce errors in physics?

1. Taking repeated measurements to obtain an average value.
2. Plotting a graph to establish a pattern and obtaining the line or curve of best fit. In this way, the discrepancies or errors are reduced.
3. Maintaining good experimental technique (e.g. reading from a correct position)

What is a precaution in an experiment?

Precautions refer to actions that can be taken by students to minimize effect on the result of experiment.

What are the precautions for simple pendulum?

• The bob of pendulum should be displaced with a small angle.
• The amplitude of the oscillation of a simple pendulum should be small.
• Fans should be switched off to reduce the air resistance.
• The simple pendulum should be oscillate in a vertical plane only.

What are the precautions of spring constant?

• Loading and unloading of weight must be done gently.
• Reading should be noted only when tip of pointer comes to rest.
• Pointer tip should not touch the scale surface.
• Loading should not be beyond elastic limit.

• Keep your used and unused cords tidy and secure to prevent damage.

What is basic electrical safety?

Electrical safety basics Don’t work with exposed conductors carrying 50 volts or more. Make sure electrical equipment is properly connected, grounded and in good working order. Extension cords may not be used as permanent wiring and should be removed after temporary use for an activity or event.

How can we prevent electrical accidents?

1. Never touch anything electrical with wet hands or while standing in water.
2. Don’t use frayed or broken cords or plug in anything with a missing prong.
3. Cover unused outlets.
4. Don’t overload sockets.
5. When unplugging, don’t yank! Pull by the plug, not the cord.

How can we prevent electric shock?

1. Never use a damaged extension cord.
2. Never use a defective electrical device.
3. Pull on the plug and not on the cable to unplug an electrical device.
4. Unplug the toaster before trying to dislodge stuck toast.
5. Before changing a lightbulb, switch the light off or unplug the lamp.

What is the importance of safety rules?

Safety rules in the workplace are important because they protect employees, customers and the company’s brand reputation. Enforcing safety rules can reduce on-the-job accidents and injuries and maximize productivity. Limiting risks can improve the work environment and job satisfaction of employees.

Why is practical physics important?

Effective practical physics enable learners to understand the connection between what can be seen and handled (hands-on) and scientific ideas that inform their observations (brains-on). Through practical activities, it is much easier to thread the connection between actions and observations.
