WRITE ABOUT HAZARDS, RISK AND PREVENTION

Force, Mass and Acceleration:

1. _{Cut an interrupt card to a known length and attach it to an air track glider.}
2. _{Set up the equipment, making sure that the air track is level, and that the card will pass through both gates before the masses strike the floor.}
3. _{Set the data logging software to calculate acceleration.}
4. _{Use scales to measure the total mass of the glider, string and weight stack. Record this value.}
5. _{Attach the full weight stack to the end of the string.}
6. _{Make sure the glider is in position and switch on the air blower. The glider should accelerate.}
7. _{Remove one weight and attach it to the glider using blu-tack. This will keep the total mass constant. (The weight stack is being accelerated too.)}
8. _{Repeat steps 6-7 removing one weight from the stack each time. Remember to attach each weight to the glider as it is removed from the weight stack.}

Measuring Waves in Solids and in Liquids:

1. ^{Set up the ripple tank as shown in the diagram with about 5 cm depth of water.}
2. ^{Adjust the height of the wooden rod so that it just touches the surface of the water.}
3. ^{Switch on the lamp and motor and adjust until low frequency waves can be clearly observed.}
4. ^{Measure the length of a number of waves then divide by the number of waves to record wavelength. It may}…
