Weight is the force exerted on an object due to gravity. Without gravity, there would be no weight experienced by an object.
A static object does not move downwards because the force of gravity acting on it is equal and opposite to the normal force exerted by the surface it rests on. This results in a state of equilibrium where the net force on the object is zero, preventing it from moving downwards.
In a floating object, the weight of the object is balanced by the buoyant force exerted by the fluid it displaces. This equilibrium occurs because the weight of the object is equal to the weight of the fluid it displaces, resulting in a net force of zero and causing the object to float.
Work done by a force is zero when the force is applied perpendicular to the direction of motion of the object. Another scenario is when the force is applied but there is no displacement of the object.
The sum of all the forces acting on an object is called the net force, not bank force. The net force determines the object's acceleration according to Newton's second law, F = ma. If the net force is zero, the object will remain at constant velocity or at rest.
This is called a net force. The net force is the combined effect of all forces acting on an object, and it determines the object's acceleration according to Newton's second law of motion.
In deep space where the gravitational force is zero, you would be essentially weightless. Weight is the force exerted by gravity on an object, so in the absence of gravity, there would be no force acting on you to give you weight.
Net force is the overall force acting on an object when all individual forces are taken into account. Balanced forces occur when the net force on an object is zero, meaning the object remains at rest or moves at a constant velocity. In contrast, unbalanced forces cause acceleration or deceleration of an object.
FALSE
In classical physics, weight is the force exerted on an object due to gravity. If an object has zero mass, it would not experience weight as weight is proportional to mass. So, for a body to have zero weight, it would need to have zero mass.
