Why walk the vertical component of velocity for a projectile adjust with time, whereas the horizontal component of velocity doesn"t change?
The vertical component changes since vertical activity is influenced by the gravitational pressure (which plot in the upright direction). The horizontal component of velocity doesn"t adjust because the gravitational force is perpendicular to this component(not along it). And also therefore can"t affect it. (A pressure needs to have a component along the motion in bespeak to influence that motion)
The stone is thrown upward at one angle. What happens to the horizontal component of its velocity as it rises? together it falls?
With no waiting resistance the horizontal component of velocity will continue to be constant, both in rising and also falling.

You are watching: Why does the force of gravity change the speed of a satellite in an elliptical orbit?

A stone is thrown increase at one angle. What wake up to the upright component the its velocity as it rises? as it falls?
A projectile is launched upward in ~ an edge of 70° from the horizontal and strikes the soil a details distance under range. For what various other angle of launch at the same speed will this projectile Land just as much away?
A projectile is introduced vertically in ~ 100 m/s. If wait resistance deserve to be ignored, at what rate will it return to its initial level?
The rate of the satellite doesn"t change because there is no component of gravitational pressure in the direction that its motion.
When a satellite is in an elliptical orbit, the gravitational pressure will have a component follow me the direction of motion at every points that the orbit, other than for the perigee and also apogee.
At what part of one elliptical orbit doesn"t planet satellite have actually the best speed? The lowest speed?
The satellite has its greatest speed as soon as its nearest the earth, and also its shortest speed as soon as it"s the furthest away indigenous the earth.

Why is Kenetic power a constant for a satellite in a circular orbit but not because that a satellite in one elliptical orbit?
The Kenetic energy is constant in a circular orbit since no work is done by gravity on the satellite.
Is the amount of kinetic and potential power a continuous for satellites in circular orbits, in elliptical orbits, or in both?
At a details point in the orbit, a satellite in one elliptical orbit has a gravitational potential energy of 5000 MJ with respect come earths surface and also a Kinetic power of 4500 MJ. Later on in that orbit, the satellites potential power is 6000 MJ. What is that kinetic power at that point?
A details satellite has actually a kinetic energy of 8 billion joules at perigee (The suggest closest to earth) and 5 billion joules at apogee(Point farthest from earth). Together the satellite travels from apogee come Parigi, just how much job-related does the gravitational force due on it? does its potential power increase or decrease throughout this time, and by how much?
3,000,000,000 J of work was done by the gravitational force. When traveling indigenous the apogee come perigee, the gravitational pressure does 3,000,000,000 J of work. As soon as traveling native the apogee come perigee, the Potential energy decreases by 3 billion joules(on this path, the gravitational pressure is convert 3,000,000,000 J of power from potential energy to kinetic energy)
