Is there force acting on a rock moving in a straight line in outer space at constant speed give reasonswhat happens if this rock comes near a planet?
Chhaviekhandelwal
Yes -gravity. (please note that there's probably not any rocks traveling in a straight line)
If it comes near a planet it will be attracted,
if the attraction is sufficient, they will collide.

∙ 11y agoForce equals rate of change of momentum. And force means "net force", so if something is preventing such changes , there is no net force. Momentum is mass times velocity, so if that isn't changing there is no force. Coming near a planet there is an external gravitational force, which will cause changes to the speed in terms of direction and magnitude. In true "outer space", there can be philosophical questions about the meaning of "speed" or "velocity" in the sense of "relative to what?".

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.
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 result of balanced forces acting on an object?
The object's acceleration is zero ... it continues moving in a straight line at a constant speed.
What will happen to an object moving at constant velocity?
Such an object is traveling at a constant speed in a straight line. Nothing will happen to it until the forces acting on it become unbalanced, or it runs into something.
Is it posible to move in a curved path in the absence of a force?
No. With no external force acting on an object, 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.

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
If an object is moving away from you and left alone what happens?
If an object is moving away from you and there are no forces acting on it,then it continues moving in a straight line at constant speed.
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 result of balanced forces acting on an object?
The object's acceleration is zero ... it continues moving in a straight line at a constant speed.

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.
Is it posible to move in a curved path in the absence of a force?
No. With no external force acting on an object, it moves in a straight line at a constant speed.
A rock moves in a straight path in space with a constant speed.is there any force acting on the rock.is there any work done when the rock moves?
There is no force acting and therefore no work done.
What will happen to an object moving at a constant speed if no outside forces act on it?
It's not necessary to specify that the object is moving at a constant speed. Any object with no outside forces acting on it does that. It also continues moving in a straight line.
Which law is assocaited with inertia?
Newton's First Law - objects stay at rest or move in a straight line at constant velocity if not forces are acting on it. (Paraphrased).
