Ms. Newton's class was conducting experiments on forces and friction. The students set up the ramp seen here. They measured the force needed to pull a wood block up the wooden ramp. That was their control or standard of comparison. They used a force of 65 Newtons to pull the block to the top
of the name. Student groups took tums changing the surface of the ramp on the left beginning with carpet. Will there be more or less friction than the
wood tamo? Predict how the friction force will change on each of the trial surfaces Drag each surface to one of the two columns
