Therefore
Distance from A-A
Therefore
Time Required to travel trough d is mathematically given as
a wedge is a small inclined plane
a screw is an inclined lane wkich goes round a centrral axis ... like a 'spiral' or helical staircase
easier per step ... more steps
When the planet is closest to the Sun, speed v and kinetic energy are the highest, and gravitational potential energy is the lowest. When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases.
