If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
Is the satellite accelerating?
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
Assume that the moon travel at constant speed in a circular orbit around the earth is the moon's velocity is constant.explain your answer.?
Speed is a scalar measure. That means that it is represented by a single number. Velocity is a vector measure. That means that it is represented by a pair of numbers (speed and direction).Even though the Moon has approximately constant speed in its revolution around Earth, its velocity is constantly changing due to the pull of Earth's gravity.Do a thought experiment: imagine a stone tied to a length of string. Imagine pulling the string in such a way that the stone travels around you in a circle. This shows that an orbit is established by a pulling force (a centripetal force). If the string broke, the stone would continue moving in the same direction it was already traveling, but its path would become approximately a straight line because there is no longer a centripetal force pulling it into a circular orbit.
Why an object in a circular orbit at constant speed is experiencing an accelaratiopn?
An object in circular orbit at constant speed is experiencing an acceleration because the orbit is circular. That is, an object is accelerating not just when its speed is changing but also when its direction is changing. In physics, acceleration refers to a change in velocity which is composed of speed and direction. Hence both a change in speed and a change in direction are, by definition, a form of acceleration.
Is orbital velocity the velocity a rocket must reach to fly off into space?
No.Orbital Velocity is the velocity required by a body to achieve a circular orbit around its primary.Escape velocity is the minimum velocity needed to escape a gravitational field
How circular velocity is constant in circular motion?
Velocity constantly changes as so does the direction around a circle...
An object traveling at a constant rate in a circular path is changing its?
velocity continuously because velocity has both magnitude and direction. In a circular path, the direction of the object's velocity is constantly changing as it moves around the circle, even though its speed (magnitude of velocity) may remain constant.
Explain why velocity changes while driving around a circular track even if the speed is constant?
While the speed may be constant, the velocity changes because velocity is a vector quantity that includes direction. As the car drives around the circular track, its direction constantly changes, causing the velocity to change even though the speed remains the same. This change in velocity is due to the centripetal acceleration required to keep the car moving in a circular path.
Is the velocity constant for an object in uniform circular?
Answer: No, the speed is constant, but the velocity changes, since the direction changes. Please be sure you understand the difference between "speed" and "velocity", as used in physics. Speed is scalar which has only magnitude but not direction Whereas velocity is having both. So is a vector quantitiy
Why a circular motion is said to be uniform when the angular velocity is constant?
A circular motion is called uniform when the object travels around a fixed point at a constant angular velocity. This means that the speed and direction of the object remains constant throughout its motion, leading to a uniform circular movement.
What remain constant in uniform circular motion?
In uniform circular motion, the speed of the object remains constant as it moves around the circle. However, the velocity of the object changes because the direction of the velocity vector is constantly changing. The centripetal acceleration remains constant in magnitude and always points towards the center of the circle.
Why is a person running around a circular track at a constant speed accelerating?
Even though the person is moving at a constant speed, they are changing direction constantly as they go around the track. Since acceleration is defined as any change in velocity, and velocity includes both speed and direction, the person running on a circular track is experiencing acceleration.
Can you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
Going around a ferris wheel without stopping is an example of what type of circular motion?
Ferris wheel goes around in uniform circular motion. The wheel traverses in a circular path at a constant speed and distance of the body from the axis of rotation is fixed as constant at all times. While the speed is constant, its velocity is not constant but changing. It is an example of centripetal force constant in magnitude acting towards the axis of rotation.
What is the formula for calculating the circular orbit velocity of an object around a central body?
The formula for calculating the circular orbit velocity of an object around a central body is v (GM/r), where v is the velocity, G is the gravitational constant, M is the mass of the central body, and r is the distance between the object and the central body.
Which physical quantity changes continuously during uniform circular motion?
The direction of velocity changes continuously during uniform circular motion. The magnitude of velocity remains constant, but its direction is constantly changing as the object moves around the circle.
