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.
What else can I help you with?
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.
How many planets does Arcturus have around it?
Arcturus is a star located in the constellation of Boötes and is not known to have any planets orbiting around it. It is a red giant star that is relatively close to Earth in astronomical terms, at a distance of about 36.7 light-years. While exoplanets have been discovered around many other stars in our galaxy, none have been confirmed around Arcturus.
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?
The force needed to slide the mass at a constant velocity is equal in magnitude and opposite in direction to the frictional force. The frictional force is calculated as the coefficient of friction multiplied by the normal force (frictional force = coefficient of friction * normal force). Hence, the force needed would be 0.43 times the weight of the mass (force = coefficient of friction * mass * gravity).
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
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.
Suppose the force of friction on a sliding object is 10N. what is the force needed to maintain a constant velocity is?
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
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?
The additional force needed to bring the car into equilibrium would be equal in magnitude and opposite in direction to the force that was providing the constant velocity. This force is the force of friction that acts to oppose the motion of the car.
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.
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 happens to your speed velocity and acceleration as you run circular laps?
As you run circular laps at a constant speed, your speed remains constant, but your velocity changes because velocity is a vector quantity that includes direction. Your acceleration points towards the center of the circle, providing the centripetal force needed to keep you moving in a circular path.
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.
Why is it necessary that a body move with uniform velocity?
Uniform velocity means constant speed and direction of motion. It is necessary for certain calculations in physics where a consistent rate of change is needed. In some cases, uniform velocity simplifies the analysis of motion as there are fewer variables to consider.
How many planets does Arcturus have around it?
Arcturus is a star located in the constellation of Boötes and is not known to have any planets orbiting around it. It is a red giant star that is relatively close to Earth in astronomical terms, at a distance of about 36.7 light-years. While exoplanets have been discovered around many other stars in our galaxy, none have been confirmed around Arcturus.
Driving along a road at a constant velocity of 100km h-1.the forces opposing the motion of the car total 800N. cars mass is 1200kg.what force do you need to maintain constant velocity?
It doesn't matter what the car's mass is, or for that matter, what speed you're talking about.If the total forces opposing its motion are 800 N, then you need to supply 800 N in the directionof motion in order to maintain a constant speed.
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
