At which point can the weight force be considered to act for an extended object?
The weight force can be considered to act at the center of mass for an extended object.
What is the weight objects act?
The weight of an object is the force exerted by gravity on that object. It is typically measured in units such as pounds or kilograms. Weight can vary depending on the gravitational force acting on the object.
How does weight affect center of gravity?
Weight directly impacts the position of an object's center of gravity. The center of gravity is the point where the weight of an object can be considered to act. As an object's weight increases, the center of gravity shifts towards the heavier end of the object.
Does An object's buoyant force and weight mean the same thing?
No, an object's buoyant force and weight are not the same thing. Weight is the force with which gravity pulls an object downward, while buoyant force is the force exerted by a fluid on an object immersed in it that opposes the object's weight. buoyant force can act in the opposite direction of weight if the object is floating in a fluid.
Does weight disappear if the air disappears?
No, weight is a measure of the force due to gravity acting on an object. Even if air disappears, the force of gravity will still act on the object, so its weight will not disappear.
How does buoyant force act on an object?
The buoyant force acts in an upward direction on an object immersed in a fluid. It is equal to the weight of the fluid displaced by the object. If the buoyant force is greater than the object's weight, the object will float; if it is less, the object will sink.
What direction does weight act in?
Weight acts in the vertical direction, pulling an object towards the center of the Earth. It is a force due to gravity and is proportional to the mass of the object.
What is in the center of gravity?
The centre of gravity is the point trough which the whole weight of the object seems to act.
What directions Do the forces of air resistance and weight act on a falling object?
The weight of a falling object acts downwards, while air resistance acts in the opposite direction of the object's motion. Weight is the force of gravity pulling the object toward the ground, while air resistance is the frictional force that opposes the object's motion through the air.
What is an objects center of mass?
An object's center of mass is the point at which all of its mass can be considered to be concentrated. It is the average position of all the mass in the object, where the object's weight can be considered to act as if it were concentrated.
Are weight and normal force action-reaction pairs?
No, weight is the force of gravity acting on an object due to its mass. Normal force is the force exerted by a surface to support the weight of an object resting on it. They are not action-reaction pairs as they act on different objects - weight acts on the object itself, while the normal force acts on the surface supporting the object.
Are normal force and weight not a third law pair?
Normal force and weight are not a third law pair because they act on the same object in opposite directions. The normal force acts perpendicular to the surface the object is in contact with to support the object's weight, which acts vertically downward due to gravity.
