Hiii I need help solving this experiment please thankyou so much in advance!

A. Calculate the box's gravitational potential energy, E, kinetic energy, Ex, and total mechanical energy, Em, for each position in Table 1: Table 3 Potential Energy Kinetic Energy TOTAL Mechanical Position ER (J) Ek (J) Energy Em (J) Initial Position A B C m [A:4] B. Draw ONE bar chart for all types of energy and answer the following. [C:4] 1. What energy changes take place in this part of the experiment? [A:2] 2. What evidence have you found that energy is conserved? [A:2]C. Answer the following questions: 1. For the box sliding down a ramp without friction, what are the relationships between: a. gravitational potential energy and position b. kinetic energy and position c. total mechanical energy and position 2. When friction is not ZERO, what effect does friction have on the : a. gravitational potential energy and position\f2. When friction is not ZERO, what effect does friction have on the : a. gravitational potential energy and position b. kinetic energy and position 3. Write the conservation of energy Law and Formula?
