Physics paper 2 (edexcel gcse) Flashcards

There are changes in the way energy is stored when a system changes. For example: an object projected upwards - The object''s energy is slowly transferred from the kinetic store to the gravitational potential store as it slows down and climbs higher. Describe an example of how work done in electrical equipment can change the energy of a system.

Lockout/Tagout-Employer Hazardous Energy Control Procedures

Locations of disconnect points (energy isolating devices) are identified, and; The sequence of steps to safely lockout or tagout the machinery or equipment are similar. OR. Machinery or equipment has a single energy supply that is readily identified and isolated and has no stored or residual hazardous energy.

Energy Changes in a System

Work is done whenever energy is transferred, so whenever you see this phrase, it just means that energy has been transferred. Electrical work done just means that energy has been transferred when a current flows. This also means that the unit of work done is the same as energy, so is measured in joules.

What is stored energy?

Stored energy (also residual or potential energy) is energy that resides or remains in the power supply system. When stored energy is released in an uncontrolled manner, individuals may be crushed or struck by objects, moving machinery, equipment or other items. How does it work? Stored energy is energy in the system which is not being used.

Is stored energy a hazard?

While most people think about lockout hazards when discussing “stored energy,” potential and elastic stored energy can also be very dangerous. This new video is designed to raise your employees’ awareness of all types of stored energy hazards in the work environments where they can be found.

What is stored energy & how does it affect workplace safety?

The Occupational Safety and Health Administration recognizes the risks that stored energy poses to workplace safety. They have created a standard that addresses the practices and procedures necessary to disable machinery or equipment and prevent the release of hazardous energy, mainly when employees perform servicing and maintenance activities.
