Gravitational Forces

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two objects with mass. It pulls objects toward each other.

Front

What factors affect gravitational force?

Back

Gravitational force is affected by the masses of the objects and the distance between them.

Front

What happens to gravitational force as distance increases?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What does it mean to be 'weightless'?

Back

Being 'weightless' means that an object is in free fall, experiencing no net gravitational force acting on it.

Front

How does gravity affect satellites in orbit?

Back

Gravity pulls satellites toward the Earth, but their high speed allows them to stay in orbit instead of falling.

Front

What is escape velocity?

Back

Escape velocity is the minimum speed needed for an object to break free from a planet's gravitational pull.

Front

Why is it important to make satellites lightweight?

Back

Making satellites lightweight reduces the energy needed to overcome Earth's gravitational pull, making them more energy-efficient.

Front

What is the role of forces in launching a rocket?

Back

Forces, including thrust from engines, must overcome gravitational force to launch a rocket into space.

Front

What is the net electrical charge's effect on gravitational force?

Back

The net electrical charge does not affect gravitational force; only mass and distance do.
