Is more gas needed to get a car moving or to keep the car moving at a constant speed?

More gas is used when you accelerate, that's why using cruise control is a gas saver, it keeps your vehicle at a constant speed.

How much force is needed to move an object?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What magnitude pushing force is needed to keep a box moving at a constant 8 meter per sec if there is a static friction of 5 lb and kinetic friction of 4 lb?
While the box is moving in a straight line at a constant speed, the push only has to overcome the kinetic friction. Whatever the speed is, and whatever the weight of the box is, 4 pounds of push IN THE DIRECTION THE BOX IS MOVING will keep this one going.
How much force is needed to keep a 2kg object moving?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What force keeps an object in free space going a constant speed?
No force is required to keep an object moving at constant speed in a straight line. Force is required only to change its speed or direction.
How can a body be accelerating when moving at constant speed?
A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
What will happen to an object if the sum of all the forces acting on a moving object is zero?
it will keep movin at a constant speed
Is there an angle for the plane at which no horizontal force can keep the mass moving at constant speed?
Sorry it is impossible to understand your question.
Since an object moving in uniform circular motion keeps a constant speed there is no force necessary to keep it in motion?
false
Will it be correct to say that the car moving in a circular path with constant speed has uniform acceleration?
No, a car moving in a circular path at a constant speed does not have uniform acceleration. While its speed remains constant, its direction is constantly changing, resulting in a non-uniform acceleration due to the centripetal force required to keep it moving in a circle.
Since an object moving in uniform circular moyton keeps a constant speed there is no force necessary to keep it in motion?
False (apex)
Why is force needed to keep object moving in a circle?
Because if there's no force acting on an object, then the object continues moving with constant speed in a straight line. Newton made that simple statement a little over 300 years ago, and nothing in our everyday experience has ever disproved it.
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.
