A student predicts that a block sliding down a ramp inclined at 45 degrees should have an acceleration of approximately 7 m/s2 The block is released from rest, and the student measures the distance the block travels and the time it takes to travel that distance. The student determines that the block’s acceleration is only 5.5 m/s2. What is the most likely reason for the difference between the predicted and calculated accelerations?
The student’s model used to make the prediction did not account for all of the forces that are exerted on the block.
