The question asks for the definition of weight. We need to differentiate weight from related concepts like mass, volume, and density.
\[ W = m \times g \]
Correct Option: B) The force of gravity acting on an object
This definition accurately describes weight. Weight is fundamentally a force, specifically the gravitational force exerted on an object. This is why an object's weight can change depending on its location (e.g., on Earth vs. on the Moon), even though its mass remains constant.
The question asks for the correct formula to calculate weight. Weight is a measure of the force of gravity acting on an object's mass. We need to recall the fundamental definition of weight in physics.
B) Weight = Mass × Acceleration due to gravity
This option correctly defines weight as the product of an object's mass and the acceleration due to gravity acting on it. The standard unit for weight is the Newton (N).
The question asks for the SI unit of weight. To answer this, we need to recall the definition of weight and its relationship to mass and acceleration due to gravity, and then identify the standard unit for force in the International System of Units (SI).
Correct Option: A) Newton is the SI unit of force, and since weight is a force, its SI unit is also Newton.
To determine which factor affects an object's weight, we need to understand the definition of weight and its relationship with other physical properties of an object. Weight is a measure of the force of gravity acting on an object.
Correct Option: B) Mass of the object. Weight is directly proportional to the mass of the object, as given by the formula \(W = m \times g\).
The question asks to identify the correct statement about weight. We need to understand the definition of weight, its nature (scalar/vector), its units, and how it is affected by external factors like gravity.
A) Weight depends on the location of the object. This statement is correct. The acceleration due to gravity (\(g\)) varies depending on the location (e.g., different planets, different altitudes on Earth). Since weight \(W = m \times g\), a change in \(g\) will result in a change in weight, even if the mass \(m\) remains constant. For example, an object weighs less on the Moon than on Earth because the Moon's gravitational acceleration is weaker.
This question asks about the weight of an object in free-fall. It's crucial to understand the definition of weight and the conditions of free-fall. Weight is typically defined as the force exerted on an object due to gravity. However, in the context of free-fall, the concept of "apparent weight" becomes relevant.
A) 0N. In free-fall, an object experiences weightlessness because there is no normal force or supporting force acting on it. The object and any measuring device (like a scale) would be accelerating downwards together, resulting in an apparent weight of zero.
