If an object is not accelerating what can you determint about the sum of all the orces on the object?
In that case, the sum of all forces must be zero.
When forces do not balance the object will be?
Accelerating
Is free fall balanced or unbalanced?
An object in free fall is accelerating, so the forces on it must be unbalanced.
Does an object that has balanced forces or no force acting on it must be stationary?
No. An object that has no net force on it will simply not be accelerating. It can be in motion, but it can not have any change in its velocity.
What forces act on an object in a lift accelerating upwards?
=== ===
When an object floats the forces of weight and the force of upthrust are?
They must be equal. We know that, because if the vertical forces on the object didn't add up to zero, then it would be accelerating vertically, either up or down.
What does the term balance mean?
If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.
What are the conditions for the forces to be balanced?
That simply means that the sum (the vector sum) of forces acting on an object is zero. Note that for an object to remain in balance, there is also a second condition: the sum of all TORQUES on the object must also be zero.
When an object is at rest what are the forces acting on it?
You never know. The only thing you know about the forces on an object that's not accelerating is: They all add up to zero, and their effect on the object is the same as if no forces at all were acting on it. That's the same as saying that all the forces on the object are 'balanced'.
How can you tell visually if the forces on an object are balanced?
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
If the force acting upon an object are balanced then the object Amust not be moving Bmust be miving with constant velocity Cmust not be accelerating Dnone of these?
If the force acting upon an object are balanced then the object must not be accelerating
How do you identify balanced forces?
The object the forces are acting on will not move, or will be moving at a constant speed (e.g. not accelerating). This is called being in 'equilibrium'.
