For an object to be in static equilibrium, the sum of the forces acting on it must be zero (ΣF = 0) and the sum of the torques acting on it must be zero (Στ = 0). This means that the object is not moving and is also not rotating. The object's center of mass must also be directly above its base of support.
What else can I help you with?
Does it take more force to make a stationary object start sliding or to make sliding object continue sliding?
It takes more force to make a stationary object start sliding because you need to overcome the static friction between the object and the surface. Once an object is already sliding, it requires less force to keep it moving due to kinetic friction, which is typically lower than static friction.
How do you determine equilibrium and resultant?
To determine equilibrium, you need to check if the sum of all forces acting on an object is zero. If the forces cancel each other out, the object is in equilibrium. Resultant force is the overall force acting on an object, taking into account the magnitude and direction of all individual forces acting on it. Mathematically, it is calculated by adding or subtracting all individual forces vectorially.
If there are two equal and opposite forces on something you say the forces are?
You say that the two forces are in equilibrium.
What foce needs to overcome to move something?
To move an object, you need to overcome the force of static friction, which is the resistance encountered when trying to move an object at rest. Once the object is in motion, you need to continue overcoming the force of kinetic friction, which is the resistance encountered while the object is in motion.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
What is need of static method?
If you need to access a method without creating an object of corresponding class, it need to be a static method.
Why static is used in main method?
It is declared static because the JVM would need to execute the main method and if it is not static the JVM would need an object of the class to access the method. How can the JVM get an object of a class without invoking it. since it is static, the JVM can easily access it without this need to have an object of the class.
How would you make an object reach equilibrium if it's not moving?
If it isn't moving, it is already in equilibrium, and you don't need to do anything more.
Does it take more force to make a stationary object start sliding or to make sliding object continue sliding?
It takes more force to make a stationary object start sliding because you need to overcome the static friction between the object and the surface. Once an object is already sliding, it requires less force to keep it moving due to kinetic friction, which is typically lower than static friction.
Can an object be in equilibrium if the object is acted on by two forces that point in directions that are not perpendicular?
Yes, an object can still be in equilibrium even if it's acted on by two forces that are not perpendicular. The forces just need to have equal magnitudes and be in opposite directions along the same line of action. This condition ensures that the net force on the object is zero, leading to equilibrium.
Is the net force acting on an object always zero?
No because if it was, nothing would ever accelerate. If you apply a net force to an object, it accelerates. The net force acting on an object is always zero if and only if it is in static equilibrium; that is, the object is not moving (rotation or translation) or moving with constant velocity. Given that an object is in static equilibrium, you can say that the net force and moments in all three cartesian directions are zero.
How do you determine equilibrium and resultant?
To determine equilibrium, you need to check if the sum of all forces acting on an object is zero. If the forces cancel each other out, the object is in equilibrium. Resultant force is the overall force acting on an object, taking into account the magnitude and direction of all individual forces acting on it. Mathematically, it is calculated by adding or subtracting all individual forces vectorially.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
If there are two equal and opposite forces on something you say the forces are?
You say that the two forces are in equilibrium.

What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
