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.
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
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.
The velocity a rocket must reach to establish an orbit around earth is called?
Orbital velocity, or Close orbital velocity.
Why do planets rotate around the sun in the same direction?
They don't rotate in the same direction. But most of the rotation comes about from the conservation of angular momentum. Angular momentum is given by L=m*w*r2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). Hope I answered your question...

How circular velocity is constant in circular motion?
Velocity constantly changes as so does the direction around a circle...
Explain why velocity changes while driving around a circular track even if the speed is constant?
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
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 type of circular motion is going around on a Ferris wheel without stopping an example of?
The type of circular motion on a Ferris wheel without stopping is an example of uniform circular motion. In this type of motion, the speed of the object remains constant, but its direction changes continuously, moving in a circle at a consistent rate.
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.
When you run around a track at 5 km h your velocity is constant?
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.
The velocity required to keed a satellite in orbit around the Earth is called?
circular velocity
Is the velocity constant if a car is going around a curve?
NO,velocity changes.
When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
Can a car move with changing velocity while maintaining constant speed?
Constant speed around a curve is changing velocity.
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.
What is nature of velocity in constant speed?
Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.
