2.Based on your observations of the spring scale in Part 2, describe all the forces actingon an elevator as it moves from rest upward and stops at its floor.
(8 points)3.Use your data from Part 3 and Newton’s laws to explain why the force meter measures aforce if the cart is moving at a constant velocity. You should cover the following points. State Newton’s first law.Identify the forces acting on the cart.Describe the relationships between applied force and mass and between applied force and weight as linear (from data or mathematical derivation by applying Newton’s first law).Explain why the data are linear in terms of Newton’s first law.
