Determine the net force on a car moving in a straight line at constant speed?

If traveling at constant speed in a constant direction then net force is zero as
there is no acceleration. Acceleration would change one or the other, or both.
F = ma = m (0) = 0

air resistance and friction.

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.
Is it impossible when an object moving in a straight line has no acceleration?
If a body is moving at constant velocity in a straight line, the acceleration is zero and the net force acting on it is zero. F = ma F = m x 0 F = 0
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.
Desciption of newtons first law of motion in everyday terms?
Anything that's moving keeps moving in a straight line at constant speed, unless a force acts on it.Anything that's not moving can't start moving, unless a force acts on it.Any change of speed or direction needs a force to make it happen.
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.
Objects moving at a constant speed in a straight are said to be in?
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
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 describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
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 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 must you know about an object that is 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.
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.
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.
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.
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.
Is a balanced force moving?
A balanced force is either not moving or at a constant velocity
