What must be the orbital speed of a satellite?

To maintain an orbit that is 22,223 miles (35,786 kilometers) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph). That orbital speed and distance permit the satellite to make one revolution in 24 hours.

How do you calculate orbital speed GCSE?

momentum = mass X velocity p = mv.
(kg m/s) (kg) (m/s)
Orbital speed = 2 X π X orbital radius / time period v = 2 π r / T.
(m / s) (m) (s)
Power = work done / time taken P = W / t.
(Watt, W) (J) (s)
(no unit) (J) (J)
electrical energy = voltage X current X time E = I t V.

What is the orbital velocity of satellite derive its equation?

The expression for orbital velocity is √g( R+h) = √gr. Orbital velocity is the velocity needed to balance the pull of gravity on the satellite with the inertia of the motion of the satellite, the tendency of the satellite to continue.

What is the equation for orbital velocity?

The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth’s radius plus the height above the earth – in this case, 6.59 x 106 m.

What are Kepler’s 3 laws in simple terms?

There are actually three, Kepler’s laws that is, of planetary motion: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its …

What is K in Kepler’s third law?

The Gaussian constant, k, is defined in terms of the Earth’s orbit around the Sun. The Newtonian constant, G, is defined in terms of the force between two two masses separated by some fixed distance.

How do you calculate Kepler’s constant?

“The square of the period of orbit, divided by the cube of the radius of the orbit, is equal to a constant (Kepler’s Constant) for that one object being orbited.”

Is Kepler’s third law universal?

Kepler’s third law (in fact, all three) works not only for the planets in our solar system, but also for the moons of all planets, dwarf planets and asteroids, satellites going round the Earth, etc. …

What does T stand for in Kepler’s law?

Kepler’s Third Law – Periods. ● For all planets, the square of the orbital. period (T) of a planet is proportional to the. cube of the average orbital radius (R), or.

Why are Kepler’s three laws important?

Kepler’s laws of planetary motion mark an important turning point in the transition from geocentrism to heliocentrism. They provide the first quantitative connection between the planets, including earth. But even more they mark a time when the important questions of the times were changing.

Do Kepler’s laws apply to moons?

Kepler’s Laws are wonderful as a description of the motions of the planets. Moreover, Kepler’s Third Law only works for planets around the Sun and does not apply to the Moon’s orbit around the Earth or the moons of Jupiter.

Are Kepler’s laws True?

Kepler’s laws are useful for making predictions of planetary motion. Observations of a planet can determine its Keplerian orbit, and from that we can compute its future path. That the laws are false indicates only that the predictions won’t be perfect.

What are Newton’s three laws?

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

What is another name for Newton’s 3 law?

noun. action and reaction are equal and opposite. synonyms: Newton’s third law of motion, law of action and reaction, third law of motion.

What are the examples of 3 laws of motion?

Examples of Newton’s third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

What is the first rule of physics?

The focus of Lesson 1 is Newton’s first law of motion – sometimes referred to as the law of inertia. Newton’s first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Law 2: Never Put Too Much Trust In Friends, Learn How To Use Enemies. Be wary of friends — they will betray you more quickly, for they are easily aroused to envy. But hire a former enemy and he will be more loyal than a friend, because he has more to prove. In fact, you have more to fear from friends than from enemies.
