Orbits in Space Quiz

What is an orbit?

• The shape of the Moon's surface

• The speed at which an object moves in space

• The force that pulls objects towards each other

• The path that an object follows around another object

What is the force that keeps the Moon in orbit around the Earth?

• Buoyancy

• Gravity

• Friction

• Magnetism

How long does it take for the Moon to fully orbit the Earth?

• 35 days

• 30 days

• 27 days

• 20 days

What is the International Space Station (ISS)?

• A satellite for weather forecasting

• A satellite where astronauts live and perform experiments

• A space telescope

• A satellite for communication

What is the cause that produces the effect of the Moon remaining in orbit around the Earth?

• Buoyant force

• Frictional force

• Balance between velocity and gravitational pull

• Magnetic force

What would happen if the Moon's speed was much faster?

• It would escape the Earth's gravity and fly off into space

• It would slow down and crash into the Earth

• It would start rotating around the Sun

• It would stop in its orbit around the Earth

What is the reason that artificial satellites don't crash into the Earth?

• They are moving too fast for Earth's gravity to pull them down

• They are made of lightweight materials

• They are too small to be affected by Earth's gravity

• They have a force field protecting them

What is the main purpose of the thousands of different satellites traveling around Earth?

• All of the above

• To monitor areas of drought

• To send signals to phones and TVs

• To forecast weather

What is the biggest factor that determines the orbit of a satellite?

• The color of the satellite

• The size of the satellite

• The gravitational pull of the Earth

• The distance from the Earth

What is the delicate balance that is super important for an object to remain in orbit?

• Balance between the object's weight and the Earth's gravity

• Balance between the object's speed and the Earth's magnetic force

• Balance between the object's velocity and the Earth's gravitational pull

• Balance between the object's shape and the Earth's atmosphere
