What is weight and how does it vary on different celestial bodies?

Back

Weight is the force exerted by gravity on an object. It varies depending on the mass of the celestial body and the distance from its center. For example, a 12kg dog weighs more on Earth than on the Moon due to Earth's stronger gravitational pull.

Which celestial body has the greatest gravitational force?

Back

The Sun has the greatest gravitational force among the options provided (the Moon, Earth, and Mars) due to its massive size and mass.

In which direction does a magnetic field move?

Back

A magnetic field moves from the North pole to the South pole of a magnet.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be felt, causing attraction or repulsion of magnetic materials.

Front

What happens when two north poles of magnets are brought together?

Back

They repel each other.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force of gravity acting on that mass, measured in newtons.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g). On Earth, g is approximately 9.81 m/s².

Front

What is the role of gravity in the solar system?

Back

Gravity keeps planets in orbit around the Sun and governs the motion of celestial bodies.

What is the significance of the Earth's gravitational force?

Back

Earth's gravitational force is essential for keeping the atmosphere, water, and life on the planet.
