Very Short Question and Answers - Mass and Weight

Mass is the measure of the amount of matter in an object and is constant regardless of its location.

Weight is the force exerted on an object due to gravity and depends on both the mass of the object and the acceleration due to gravity.

Weight is directly proportional to mass; it can be calculated using the formula W = m × g, where W is weight, m is mass, and g is the acceleration due to gravity.

Mass is a scalar quantity that measures the amount of matter in an object and remains constant, whereas weight is a vector quantity that measures the gravitational force on the object and varies with location.

The weight of an object on the Moon is one-sixth of its weight on Earth due to the lower gravitational pull of the Moon.

The weight of an object on the Moon is 1/6th its weight on Earth because the Moon's gravitational acceleration is approximately 1/6th that of Earth's.

Greater mass results in greater inertia, meaning it requires more force to change the object's state of motion.

No, the mass of an object remains constant regardless of its location.

A camel can run easily in the desert due to its specialized adaptations, such as wide feet that distribute its weight over sand.

An army tank rests on a continuous chain to distribute its weight evenly over a larger area, reducing pressure on the ground.

Trucks and buses have wider tires to distribute their weight over a larger area, which helps in reducing ground pressure.

The formula for calculating weight is W = m × g, where W is weight, m is mass, and g is the acceleration due to gravity.

An object's weight in outer space decreases significantly due to the reduced gravitational pull, but its mass remains unchanged.

Gravity affects the weight of an object by determining the force with which it is pulled towards the center of a celestial body.

Weight is a vector quantity because it has both magnitude and direction.

The weight of a 10 kg object on Earth is 98 N, calculated using W = m × g (10 kg × 9.8 m/s²).

The weight of a 10 N object on the Moon would be 1.67 N, as it is one-sixth of its weight on Earth.

Gravitational pull causes objects to attract each other, leading to phenomena such as falling objects and orbits of celestial bodies.

In the absence of air resistance, heavier and lighter objects fall at the same rate due to gravity.

Newton's thought about gravity led to the understanding that the same gravitational force that attracts an apple to the Earth also governs the motion of the Moon around the Earth.
