On account of the way gravity works, any satellite in any orbit of any shape moves faster

when it's nearer the central body, and slower when it's farther from the central body. If it's in

a circular orbit, then its speed is constant.

But kinetic energy is 1/2MV2 ... 'M' is mass, and 'V' is speed ... so if the speed doesn't change,

then the kinetic energy doesn't change.

Which physical quantity remains constant in an elastic collision?

In a uniform circular motion,the magnitude of velocity remains constant,that is speed is constant,however due to change in direction in circular path constantly the motion is accelerated due to change in velocity.


What is the relationship between centripetal kinetic energy and the motion of an object in circular motion?

Centripetal kinetic energy is the energy associated with an object's motion in a circular path. It is directly related to the speed and mass of the object, as well as the radius of the circular path. As the object moves in a circular motion, centripetal kinetic energy is constantly changing to keep the object moving in a curved path.


When is kinetic energy conserved in a system?

Kinetic energy is conserved in a system when there are no external forces acting on the system, meaning that the total amount of kinetic energy remains constant.


Does gases have kinetic energy?

Yes, gases have kinetic energy because the particles in gases are in constant motion. This motion is a form of kinetic energy, which increases as the temperature of the gas increases.


What is the opposite of kinetic?

Normally, in most contexts, the opposite of "kinetic" (moving) could be "static" (not moving). When talking about 'energy' the opposite of "kinetic" can be "potential", i.e., kinetic energy vs potential energy. An object in ballistic motion (i.e., moving only under the influence of a simple gravitational field) may exchange its energy between kinetic and potential forms, perhaps even repeatedly, but the sum of the two will remain constant. Examples (neglecting friction) include a pendulum, a roller coaster and a satellite in an elliptical orbit.

What does the work-energy theorem say about the speed of a satellite in circular orbit?

Not very much, I would say. There is no work being done in this situation so there's no change in kinetic energy. So the satellite's speed remains constant. But we already knew the speed was constant. Perhaps I'm missing something.


The potential energy of a satellite in an elliptical orbit is?

The total energy of a satellite doesn't change. At its closest approach to the planet, it has the most kinetic energy and the least potential, whereas at its furthest retreat from the planet, it has the least kinetic energy and the most potential. But their sum ... the satellite's total mechanical energy ... is always the same. (It may gain heat energy when the sun is shining directly on it, and lose it when it's in the planet's cold shadow, but neither of those changes affects its orbit.)


Which physical quantity is conserved of an earth satellite?

Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.

Does a body in circular motion have kinetic energy?

Yes, a body in circular motion does have kinetic energy. This kinetic energy is known as rotational kinetic energy and depends on factors such as the mass of the object, its radius of rotation, and its angular velocity.


What two quantities is necessary for uniform circular motion?

The only thing required for an object to show uniform circular motion is a constant centripetal force. The object will have constant speed and kinetic energy, but its velocity, acceleration, momentum, and displacement will change continuously.

What happens to the kinetic energy when you increase the speed but keep the mass constant?

When you increase the speed while keeping mass constant, the kinetic energy increases. Kinetic energy is directly proportional to the square of the velocity, so as speed increases, kinetic energy increases even more rapidly.


What happens to kinetic energy and potential energy in a closed system?

In a closed system, the total energy (kinetic + potential) remains constant, following the principle of conservation of energy. As kinetic energy increases, potential energy decreases, and vice versa. This continuous exchange between kinetic and potential energy allows the system to maintain a constant total energy.
