An airplane travels in a straight line directly from washington, d. c., to atlanta, georgia. ignoring take off and landing, what is constant throughout the majority of the flight? a. distance b. time c. velocity d. temperature

Velocity

Explanation:

As we know that for the equilibrium of flight in air the force due to air pressure must counterbalance the weight of flight.

Now here the force due to air pressure is generated by the condition of air flow above the wings

Now in order to maintain a sufficient pressure on the wings so that it will counterbalance the weight it requires a fixed flow rate of air above and below the wings

Now in order to maintain this flow speed of air the velocity of flight must have to maintain at a fixed value.

So here we can say for any flight to move from one point to other its velocity in air must remains constant throughout the motion.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
