Use your data (attachment) from Part 3 and Newton’s laws to explain why the force meter measures a force if the cart is moving a
t 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.
• Graph F versus mass + cart.

No force contributes to density, the density is a physical quantity that is defined as being 
the raport between the mass of the object and its volume. However if you want to measure the density of an object you might want to determine its gravity force (weight) 
from which knowing the gravitational acceleratin you can find its mass

Explanation:
The loss in potential energy of the boy is given by:
where
m = 40 kg is the mass of the boy
g = 9.8 m/s^2 is the acceleration of gravity
is the total change in the height of the boy (4 metres + 2 cm due to the compression of the spring)
Substituting, we find
