Upon arrival, you measure the actual force of gravity to be 6x105 N, which is different from your calculated value in question 1. Identify 2 specific possible causes that would account for the difference in expected vs. actual values, and why they would affect the calculation.

Why is there friction between objects

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j
