Questions and Answers

What is matter?

Matter is everything that has mass and volume.

How is mass measured?

Mass is measured in grams or kilograms using balances and comparing it to standard masses.

What is the difference between mass and weight?

Mass is the amount of matter in a body that does not change, while weight is a measure of the Earth's attraction to a body.

How can weight be measured?

Weight is measured using a spring scale in units called newtons. Signup and view all the answers

Why do objects weigh differently on the moon compared to Earth?

Objects weigh less on the moon because the Moon's gravitational force is less than Earth's. Signup and view all the answers

Study Notes

Matter and Mass

Matter is everything that has mass and volume.
Mass is the amount of matter in a body and remains unchanged.
Mass is measured in grams or kilograms (1 kg = 1000 g).
Scientists use balances to measure mass by comparing it to standard masses.

Weight

Weight is a measure of the Earth's attraction to a body.
Weight varies on different planets and moons due to differences in gravitational forces.
Weight on the moon is less than on Earth because the Moon's mass is less than the Earth's mass.

Measurement of Weight

Weight is measured using a spring scale.
Weight is measured in newtons (1 newton = the force of Earth’s attraction for a mass of approximately 1.1 kg).

States of Matter

In solid bodies, molecules are closely aligned.
As energy increases, molecules begin to move and spread out, occupying more space.
