Understanding Gravity and Satellites

What is the effect of gravity on objects?

• Gravity causes objects to float in the air.

• Gravity pulls objects towards the center of the Earth.

• Gravity has no effect on objects in space.

• Gravity is only felt by large objects like planets.

What role does gravity play in the movement of objects on Earth?

• Gravity pulls objects towards the Earth, affecting their speed and direction of movement.

• Gravity only influences the motion of celestial bodies, not objects on Earth.

• Gravity repels objects from the Earth, causing them to float.

• Gravity does not impact the movement of objects, only their temperature.

What is a natural satellite?

• A natural satellite is a man-made object in space.

• A natural satellite is a planet that orbits the sun.

• A natural satellite is a type of star.

• A natural satellite is a celestial body that orbits a planet.

Can you name a natural satellite of Earth?

• Jupiter

• Mars

• Moon

• Venus

What is the primary purpose of an artificial satellite?

• To provide communication services on Earth.

• To explore the surface of other planets.

• To collect data about the Earth's atmosphere.

• To serve as a natural satellite for a planet.

Give an example of an artificial satellite.

• Hubble Space Telescope

• International Space Station

• Mars Rover

• Voyager 1

How do satellites stay in orbit around Earth?

• Satellites are powered by solar panels that push them forward.

• Satellites float in space without any need for speed or gravity.

• Satellites are held in place by large thrusters that counteract gravity.

• Satellites stay in orbit because of a perfect balance between gravity and inertia (forward motion).

What happens to a satellite if there is no gravity?

• The satellite would drift away into space.

• The satellite would gain speed and return to the ground.

• The satellite would orbit the Earth indefinitely.

• The satellite would be pulled towards the nearest planet.

How do scientists launch artificial satellites into space?

• Using drones to carry satellites

• Launching satellites with balloons

• Deploying satellites from submarines

• Scientists launch artificial satellites into space using rockets.

What is the primary purpose of placing satellites in orbit around the Earth?

• To ensure they can communicate with ground stations without interruption.

• To allow them to observe and collect data from space.

• To prevent them from colliding with other space debris.

• To enable them to travel to other planets.
