Weight and Mass

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

What happens to gravitational force as distance increases?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is the SI unit of mass?

Back

Kilogram (kg).

Front

What is the SI unit of weight?

Back

Newton (N).

Front

How does the mass of an object affect its weight on different planets?

Back

The mass remains constant, but weight varies due to different gravitational accelerations on each planet.

Front

What is the relationship between mass and inertia?

Back

Inertia is the resistance of an object to change its state of motion, and it is directly proportional to mass.

Front

What is the concept of gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, proportional to their masses and inversely proportional to the square of the distance between them.
