Question

Explain how you can calculate the magnitude of friction between surfaces using only a block and force probe (i.e. a machine that only measures pulling.) be as specific as you can.

Answer 1

To calculate the magnitude of friction between surfaces using a block and force probe, measure the force needed to pull the block, divide by the weight of the block to find the coefficient of friction, and multiply by the normal force to calculate the magnitude of friction.

Step-by-step explanation:

To calculate the magnitude of friction between surfaces using only a block and force probe, you can use a few steps:

1. Measure the force needed to pull the block using the force probe.
2. Divide this force by the weight of the block to find the coefficient of friction.
3. Multiply the coefficient of friction by the normal force acting on the block to calculate the magnitude of friction.

For example, if the force measured by the force probe is 10 N and the weight of the block is 5 N, the coefficient of friction would be 10 N / 5 N = 2. The magnitude of friction would then be 2 (coefficient of friction) * Normal force.
