What is the net force or the resultant force acting on an object in equilibrium?
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
If this acts on an object the object will change speed and direction?
You mean a force I guess. A force acting on an object will make it accelerate or decelerate, and if it is acting at an angle to the existing line of motion will make it change direction.
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.
Can balanced forces act on a moving object explain your answer?
When the forces on an object are balanced, then they have the same effect on itas NO FORCE at all would have. That means that the object does not accelerate,and THAT means that it continues moving in a straight line, at a constant speed.If that didn't blow your mind, then please read it again. One of the things it tells usis that it doesn't take ANY FORCE to keep an object moving.
Explain why the polygon of forces must close when a body is in equilibrium?
The answer is in the definition: polygon of forces(plural polygons of forces) # (mechanics) A polygonal figure the sides of which are vectors representing several forces acting simultaneously upon one point, so that the vector necessary to make the figure closed is the resultant of those forces.

unbalanced
When the forces acting on an object are balanced the net force on the object is?
This is called balanced forces and no acceleration is present.
What term best describes the forces acting on an object with the net force of zero?
An object at rest, or an object with a constant velocity are the two possible states of an object with zero net force. An object with zero acceleration has zero net force. There many be several forces acting on the object, such as the force of gravity and the normal force of the ground. Even though an object sitting on the ground has two forces acting on it (gravity, and the normal force) the object does not accelerate because these forces are equal and opposite. An object with zero net force has all forces acting on it equally balanced and cancelling out
Are there forces acting on an object that's at rest?
Yes, there are always forces acting upon things, even when at rest (although all motion is relative so nothing is really "at rest"). There are some that are visible to the naked eye. For example, wind and corrosion. There are also forces that are not visible to the naked eye. Like the forces that make the electrons spin around the nucleus, the forces that hold the object together, etc....
Why is the acceleration of an object moving at a constant velocity always 0?
Acceleration is the change in velocity of an object. If an object is travelling at an unchanging speed, its speed is neither increasing (which would make a positive acceleration) nor decreasing (which would make a negative acceleration). Thus, the acceleration is 0.
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.
When forces acting on a moving object are what the object will travel at a constant speed?
You're fishing for "balanced", but that still doesn't make the statement true.An object on a curved path can have constant speed even though the forceson it are not balanced.
How can you make and object accelerate?
An object will accelerate if and only if there is a net force acting on the object.
What is the net force or the resultant force acting on an object in equilibrium?
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
Can unbalanced forces stop a moving object?
Yes.For the velocity of an obejct to change (e.g. to make a moving object slow down and stop) there must be a resultant force acting on it. This only occurs if the forces acting on it are unbalanced.Yes.For example :When we cycle fast and while going if we cross a speed breaker or an area of the road which is not smooth , there will be more friction thereby reducing the speed of the object or otherwise stopping it.
If this acts on an object the object will change speed and direction?
You mean a force I guess. A force acting on an object will make it accelerate or decelerate, and if it is acting at an angle to the existing line of motion will make it change direction.
What forces make things float?
Gravity. When you place something on a liquid, and it is less dense than the liquid, gravity pulling down on the liquid forces the object to float.
