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.

To keep an object moving in a straight line at a constant speed, you need to apply a force equal to the force of friction or any other resistive forces acting on the object. This force is called the net external force and is equal in magnitude but opposite in direction to the sum of all resistive forces.

If an object has no net force acting on it?
If an object has no net force acting on it, it will either remain at rest or continue moving at a constant velocity in a straight line, following Newton's first law of motion.
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 happens to the motion of an object if the net force acting on it is 0 n?
If the net force acting on an object is 0 N, the object will continue to move at a constant velocity in a straight line according to Newton's First Law of Motion.
What is Motion without acceleration?
Motion without acceleration is when an object is moving at a constant speed in a straight line. In this scenario, the object's velocity remains constant and there is no change in its speed or direction.
Is a force needed to keep a moving spacecraft moving in a straight line?
No, a force is not needed to keep a moving spacecraft moving in a straight line in the vacuum of space. According to Newton's first law of motion, an object in motion will remain in motion with a constant velocity unless acted upon by an external force.
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
What does inertia cause a moving object to do?
Inertia causes a moving object to continue moving in a straight line at a constant speed unless acted upon by an external force.
The net force on an object moving with constant speed in circular motion is in which direction?
The net force on an object moving with constant speed in circular motion is directed towards the center of the circle. This force is called the centripetal force and is required to keep the object moving in a circular path instead of moving in a straight line.
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.
Since an object moving in uniform circular moyton keeps a constant speed there is no force necessary to keep it in motion?
While the speed of an object moving in uniform circular motion remains constant, there is a centripetal force required to constantly change the direction of the object's velocity. This force is responsible for keeping the object moving in a circular path rather than a straight line. Without this centripetal force, the object would move in a straight line tangent to the circle.
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.
What describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
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.
If an object has no net force acting on it?
If an object has no net force acting on it, it will either remain at rest or continue moving at a constant velocity in a straight line, following Newton's first law of motion.
What is the tendency of a moving object to keep moving in a straight line?
It is known as inertia, the tendency of an object to resist changes in its velocity. This means that an object in motion will continue moving at a constant speed in a straight line unless acted upon by an external force.
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.
