9 Airplane Takeoff
When an airplane takes off, its speed increases from 300 km/h to 600 km/h, and its
altitude with respect to the ground becomes 600 m.
9.1. What is the nature of the motion of the airplane? Justily.
9.2. Does the kinetic energy of the airplane increase or decrease?
9.3. How do its gravitational potential energy and
mechanical energy vary?
9.4. Where does the mechanical energy gained by
the airplane come from?

Well the magnitude of its acceleration related to that car starts with the oil change like when you have to change the oil in your car you have to make sure that your precious car is starting really propley and very well

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.

Electrical charge is measured in coulomb.(c). the amount of an electrical charge that moves in a circuit depends on the current flow and how long it flows for. a current of 10 a flows for 30 s,then 10 x=300 coulombs of electrical charge moves
