To conduct this experiment, the following tools are typically required:
When moving at a constant speed, the pulling force shown on the dynamometer is equal to the sliding friction force ( Record this initial value in your data table.
Pull the block across different surfaces (e.g., glass vs. sandpaper) while keeping the weight constant. fizika 7klass laboratornaia rabota3 izuchenie sily treniia
To change the load (normal force) on the block.
Place one weight on top of the block and repeat the measurement. Add a second weight and measure again. To conduct this experiment, the following tools are
Rougher surfaces like sandpaper will show a significantly higher friction force than smooth surfaces like glass.
Used to measure the force applied to the object. Wooden block: The primary object being moved. To change the load (normal force) on the block
Place the block on two round pencils and pull it uniformly.
