Gravity + Magnets

Front

What is mass?

Back

Mass is the amount of matter in an object, measured in kilograms or grams.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

How does mass affect gravitational force?

Back

As mass increases, the gravitational force between two objects also increases.

Front

What is gravity?

Back

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

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, attracting certain metals like iron.

Front

What is the Earth's magnetic field?

Back

The Earth's magnetic field is the magnetic field that extends from the Earth's interior out into space, affecting compass needles.

Front

Why does a compass needle point north?

Back

A compass needle points north because it aligns with the Earth's magnetic field.

Front

What is the difference between mass and weight?

Back

Mass is a measure of matter, while weight is the force of gravity on that mass.

Front

What happens to gravitational force as distance increases?

Back

As distance between two objects increases, the gravitational force between them decreases.

Front

What is a bar magnet?

Back

A bar magnet is a rectangular piece of magnetized material with a north and south pole.
