Why is force needed to keep the planets orbiting the sun at constant velocity?

orbits occur if either a ring of asteroid rock and dust collects into a ball, or a body travelling a a high velocity passes by the larger body and is pulled in by the gravitational field. I this case, the velocity is required to produce central fugal force on the object, otherwise it will be pulled into the larger body.

Is a force needed to keep a moving spacecraft moving in a straight line?
It depends where the space craft is. If it is in deep space far away from any large mass (like a planet, star, etc) then the answer is no. If it is close to a mass then the answer is yes. An equal and opposite force is required to balance the gravitational force to keep it moving in a straight line.
What force is needed to slide a mass of 54 kg at a constant velocity along a surface on which the coeffcient of friction is 0.43?
As mass is to be moved with constant velocity, so a=0; F(net)=0; F-f=0; F=f; F=u*N; F=u*m*g; F=.43*54*9.8=227.556N...
What type of celestial body is venus is it rocky or a gas giant?
All four of the inner planets are relatively small, rocky planets, like Earth. The gas giants needed to be farther away from the sun to form. Scientists have observed evidence of gas giants orbiting very close to their stars in other star systems, but they are not believed to have originated there.
How do you calculate distance when given velocity and weight?
More information is needed.
How does the sun hold the planets in orbit?
The Sun's gravity is trying to pull the planets towards it. But the planets have their own velocities and all the Sun's gravitational attraction is needed to stop the planets moving away from the Sun. The result is that the planets orbit the Sun.
Where does force needed to keep planets orbiting the sun come from?
The force is provided by the Sun's gravitational attraction.
Before the 17th century what ideas did people have concerning motion velocity and acceleration?
There were many different ideas, but they all went something like this: Most people thought that the natural state of an object was at rest, and that force needed to be applied in order to keep an object moving at constant velocity. Of course, we now know that no force is needed for constant velocity, only acceleration.

A car goes forward along a level road at constant velocity The additional force needed to bring the car into equilibrium is?
Zero.
What equals to the constant velocity needed to cover the given displacement in a given time interval?
The required velocity is the given displacement/the given time intervalin the direction from the starting point to the end point.
Does an unbalanced force needed to change the direction of a things motion?
Yes. An unbalanced force is needed to change the direction of an object's motion. This is an example of Newton's first law of motion which states that a body at rest will remain at rest and a body in motion will remain in motion in a straight line at constant velocity unless acted upon by an unbalanced force. Constant velocity means the same speed and direction. So if the direction changes, so does the velocity.
What is a cvc joint?
A Constant Velocity Joints or CV joints are attached to each end of a drive shaft The CV joints are needed to transfer the torque at a constant speed to steered wheels as well as to accommodate up and down motions of the suspension
Are all stars and planets are about the same age?
All of the planets are in the same atmosphere. All of the planets are unique. All of the planets are considered planets. All of the planets have moons. All of the planets are named after a mythical person or thing.

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
