Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

Q1. Newton's second law is valid for an observer attached at the inertial frame. Usually, we make the
approximation in using Newton's law calculating accelerations with respect to an observer on earth.
Although -strictly speaking, this is wrong- the error made is often negligible. But how much of an
error do we really make in using these assumptions? Are they really negligible? The questions below
will help you find the answer.
Assume an aircraft flying from Istanbul straight south to Cape Town, South Africa at a constant speed
of 800 km/h. (Fig.1)
a. What is the average acceleration the aircraft will have due to earth's curvature only in order
to maintain constant altitude?
b. What is the average acceleration due to the earth's curvature and earth's rotation around
combined in order to maintain constant altitude?
(Assume perfect sphere, neglect rotation around sun)
Hint: You may calculate the acceleration by attaching a coordinate system at the airplane
(Tangential and normal coordinates).

On Mars, the acceleration due to gravity is 6.64 m/s2. What would a rock’s speed be 6 s after you dropped it on Mars?
The gravitational acceleration on Mars is 3.72 m/s2. The density of water is 1000 kg/m3. Starting from these assumptions, estimate the specific weight of water on Mars in lbf/ft3. Note that when converting lbm (pounds mass) to lbf (pounds force), a unit conversion called gc is required (1 lbf = 32.2 lbm ft s-2). The conversion factor ensures that (under normal gravity), a 100 lbm load generates 100 lbf of gravitational force
Five objects in a region where the acceleration due to gravity is 30.2 ft/s2 are as follows: x1 = 350 g of mass; x2 weighs 950gf; x3 weighs 25 poundals; x4 weighs 2lbf; x5 is 0.40 slug of mass. What is (a) the total mass expressed in gm, and (b) the total weight expressed in kgf.
