Worked Solution & Example Answer:The teacher pulls a wooden block through a fixed distance and calculates the work done from their measurements - OCR Gateway - GCSE Physics - Question 15 - 2022 - Paper 1
Step 1
Describe how the teacher can do this experiment, including any equipment used. Use the Data Sheet.
Answer
To conduct the experiment of pulling a wooden block, the teacher should use the following equipment:
-
Wooden Block: This is the object being pulled and has a measurable mass.
-
Masses: Additional weights can be added to the wooden block to increase its mass, allowing for various trials.
-
Measuring Tape or Ruler: This helps in measuring the fixed distance through which the block is pulled.
-
Force Meter (Newton Meter): This device should be used to measure the force applied when pulling the block.
-
Data Sheet: A table or sheet is required to record the mass and the corresponding work done, which is calculated using the formula:
-
Surface: A smooth surface is necessary to reduce friction, allowing for accurate measurements of work done.
Experimental Steps:
- Set up the apparatus with the wooden block on a horizontal surface.
- Attach the masses to the block and record the total mass.
- Use the force meter to pull the block over a set distance and measure the force applied.
- Calculate the work done for each mass using the formula provided and record the results in the data sheet.
