Place the wooden block on a flat horizontal surface. Attach the dynamometer and pull the block uniformly (at a constant speed).

Rougher surfaces like sandpaper will show a significantly higher friction force than smooth surfaces like glass. fizika 7klass laboratornaia rabota3 izuchenie sily treniia

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. Place the wooden block on a flat horizontal surface

Place one weight on top of the block and repeat the measurement. Add a second weight and measure again. When moving at a constant speed, the pulling

Such as a smooth wooden board, glass, and sandpaper. Round pencils or rollers: To demonstrate rolling friction. 2. Procedural Steps

Place the block on two round pencils and pull it uniformly.

To change the load (normal force) on the block.
