How much force does it take to keep an object moving in a straight line at a constant speed?

The absence of any force that affects speed and direction on the certain object. If there are none of these forces to affect the object, then the object will not be affected and will not change.

Can an object be moving if the net force is acting on zero?
Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
What is velocity if the net force is 0?
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
What happens to the motion of an object if the net force acting on it is 0 n?
Nothing happens to its motion, and it continues moving in a straight line at constant speed.
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.
Does an object moving in a constant speed in a straight line have any forces acting on it?
It will have zero force BUT, it WILL have a constant velocity
Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?
-- An object with no net force on it continues moving at constant speed in a straight line.If it's not moving in a straight line, then there must be net force acting on it.-- "Acceleration" is the word for the situation where either speed or direction of motion changes.Even if speed is constant, acceleration is present if the direction is changing.
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.
What is the net force on an object with constant velocity?
If the object is moving in a straight line, then the net force on it is zero. If the object is not moving in a straight path, then there is some non-zero net force acting on it even if its speed is constant. We don't have enough information to describe the magnitude or direction of the force.
What describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
Why there must be an unbalanced force acting if an object is moving in a circle at constant speed?
If an unbalanced force was not acting upon it, it wouldn't be moving in a circle.An object with no unbalanced force will either not be moving, or be moving in a straight line due to Isaac Newtons 1st law of motion.
What state do you called an object with a net force of 0?
The object is in constant, uniform motion. It's moving in a straight line, and at a constant speed ... which may be zero but doesn't need to be.
Can an object can be moving if the net force acting on the object is zero?
Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.
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.
Is it possible for an object to be in motion and have a zero net force?
Yes. The object will simply continue moving at a constant velocity, i.e. at a constant speed in a straight line. This is Newton's First Law.
What will an object in straight-line motion tend to do?
An object in motion tends to keep moving in a straight line at a constant speed,unless an external force acts on it to change its direction or speed.
What must you know about an object Moving in a straight line to calculate its acceleration?
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
