FAQs on What is Weight? Video Lecture - Mathematics for Class 3: NCERT

1. What is weight in physics?
Ans. In physics, weight is the force exerted on an object due to gravity. It is the measure of the force of gravity pulling on an object.
2. How is weight different from mass?
Ans. Mass is the amount of matter in an object, while weight is the force exerted on that object due to gravity. Mass is a scalar quantity, while weight is a vector quantity.
3. Does an object's weight change in space?
Ans. An object's mass remains constant in space, but its weight can change depending on the gravitational pull of the celestial body it is near. For example, an object will weigh less on the moon compared to Earth due to the moon's lower gravitational force.
4. How is weight measured?
Ans. Weight is typically measured using a scale or balance. The unit of measurement for weight is the Newton (N) or pound (lb), depending on the system of measurement being used.
5. Can weight be negative?
Ans. In most cases, weight is considered a positive value as it is a force exerted in a specific direction. However, in certain scenarios, weight can be negative when considering the direction of the force relative to a reference point.
