What is gravitational force?

Back

Gravitational force is the natural force that pulls objects toward each other. It is what keeps us on the ground and causes objects to fall.

Why do objects fall at different speeds on Earth?

Back

Objects fall at different speeds due to air resistance, which can slow down lighter or larger objects more than heavier or smaller ones.

What causes day and night?

Back

Day and night are caused by the Earth's rotation on its axis, which makes different parts of the Earth face the Sun or move away from it.

Back

The force of attraction between any two objects is called gravity.

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, affecting how fast it falls.

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull. This is why Earth has a strong gravitational force.

What happens to gravity as distance increases?

Back

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

Front

What is weight?

Back

Weight is the measure of the gravitational force acting on an object, usually measured in newtons or pounds.

Front

How does gravity affect the motion of planets?

Back

Gravity keeps planets in orbit around the Sun by pulling them toward it while they move forward.

What is the relationship between gravity and falling objects?

Back

Gravity causes all objects to fall toward the Earth at the same rate, regardless of their mass, unless affected by air resistance.
