What would you do in order to find the normal force? List the materials you would use, along with the steps you would use to find it.

What would you do in order to find the friction force? List the materials you would use, along with the steps you would use to find it.

In an experiment, you pulled a 2 kg block with a constant velocity three times, and measured the following values for the force of friction: a. )Find the average friction force. (remember to use the correct units)

In an experiment, you pulled a 2 kg block with a constant velocity three times, and measured the following values for the force of friction: b.)Calculate the coefficient of friction between the block and the surface.

In an experiment, you pulled a 2 kg block with a constant velocity three times, and measured the following values for the force of friction: c) What are some possible sources of error that could have caused groups to get different answers for the same materials?

A metal block that has a mass of 2 kg has an additional 0.5 kg mass sitting on top of it. The block and mass system are pulled with a constant velocity on a surface where the coefficient of friction between the block and surface is 0.75. What is the friction force? Don't forget the unit for force.

You want to find the coefficient of friction between a book and the table it rests on, by dragging the book across the table with a constant velocity.

Draw the appropriate free body diagram for this situation.
