Students associate pushes and pulls with moving or active objects they often believe that stationary or passive objects have no forces acting on them at all.
For example, students consider that an active object like a human hand can experience and produce forces, whereas a passive book lying at rest on a table is free from all forces. This view may be commonly held in the middle years and may be still be held by some students in the senior secondary years.
Students do have everyday experiences of objects breaking or bending when big forces are applied to them but they often fail to recognise that forces are present when there is no observable change or distortion as the force acts. For example, a chair collapsing under the weight force of a person or the stretching of a trampoline are seen to involve forces at work whereas an apple resting in a fruit bowl is not.
For both stationary and moving objects with unchanging speed and direction, all the forces acting on the objects are in balance with each other, i.e. they all cancel each other out.
Passive objects exert forces on objects that are exerting forces on them. For example, a heavy bag resting on a bed pushes on the bed because of its downward weight force and the bed pushes back up on the bag with a balancing force as it is squashed under the load.
All objects undergo some squashing (compression) or stretching and change shape when a force is applied to them. In the case of strong materials like concrete or steel table frames this compression is usually very small and not observable unless the applied force is very large.

∙ 14y agoif an object is stationary it means equal forces are being applied on the object i.e. equal and opposite. they cancel each other due to which the object does not move.

∙ 14y agoThere are a tremendous number of forces at work in the universe, but they can be broken down into four basic types, which are, the gravitational force, the electromagnetic force, the strong nuclear force, and the weak nuclear force.

What happens when balanced forces are applied to a non moving object?
It stays the same
The force exerted by a liquid on an immersed in it is called?
"What is the force exerted by a still liquid on an immersed non-moving object called? -- PressureOtherwise, if the object is moving, one could also have "shear forces".
Can there be forces that act on a car moving in a straight line with constant speed?
Yes, but the net force is ZERO! If an object is moving at constant velocity, the sum of the forces acting upon it is zero. If at any time the sum of the forces -- sometimes called the net force -- is non-zero, the object will accelerate in the direction of the resultant force.
Must there be an unbalanced net force acting on any moving objects?
Yes, whether an object will move or stay stationary in its place, or move in contant velocity depends on the NET force that is acting on it. * If there is a balanced force, ( all forces cancel each other out) , then the object will not move, or stay moving at a constant velocity (a=0) * If there is an unbalanced force, (forces donot cancel), then the object will move.
What does not happen to a non moving object in equilibrium?
it does not accelerate

Do force always got to cause motions?
No. A non-moving object has forces acting on it, but the forces are in balance in such a case.

What is non-contact frce?
Non-contact forces are forces exerted on an object by another object which is not in contact with it, a good example being gravitational force.
Must there be an unbalanced net force acting on any moving objects?
Yes, whether an object will move or stay stationary in its place, or move in contant velocity depends on the NET force that is acting on it. * If there is a balanced force, ( all forces cancel each other out) , then the object will not move, or stay moving at a constant velocity (a=0) * If there is an unbalanced force, (forces donot cancel), then the object will move.
What does not happen to a non moving object in equilibrium?
it does not accelerate
Can a can do the cancan?
No, it can't, for it is meerly a non moving object.
Does an object have net force if it is motionless?
Yes, but the net force is ZERO! If an object is moving at constant velocity, the sum of the forces acting upon it is zero. When an object is motionless, its constant velocity is zero. If at any time the sum of the forces -- sometimes called the net force -- is non-zero, the object will accelerate in the direction of the resultant force.
Is it true or false that unbalancing the forces acting on an object gives you net force?
It is true that if the forces on an object are not balanced then there will be a non-zero net force on that object.
Which are the interolecular forces that can act between non-polar molecules?
London dispersion forces
What are the similarities between balanced and unbalanced forces?
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
