An object in space is observed to have an altitude of 1200 nary (2209 km), a velocity of 7000 m/s, and an elevation angle (phi) of +40 degree. give a complete description of the trajectory. is there anything special or different about this trajectory? find v, v, and phi when r = 6.378 x 10^6 m. sketch the trajectory and locate this point.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the force on the thing and the distance the force moves the thing

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
