GRAVITY BASICS
What is gravity?
Gravity is the force that pulls objects toward each other.
How does gravity affect shape?
Gravity can cause objects to change shape, like how a rubber ball compresses when thrown.
Who discovered gravity?
Sir Isaac Newton is credited with discovering gravity.
Name a sport that uses gravity
Basketball uses gravity when players jump to shoot the ball.
How does gravity affect falling objects?
Gravity pulls objects down toward the Earth, causing them to fall.
What happens to an object in space with no gravity?
An object would float freely and not fall to the ground.
What is the gravitational force
It is the force that attracts two bodies towards each other.
How do roller coasters use gravity?
Roller coasters use gravity to pull cars down steep drops, creating thrilling rides.
What is weight?
Weight is the measure of the force of gravity acting on an object.
How is gravity related to mass?
The more mass an object has, the stronger its gravitational pull.
How does gravity change with distance?
Gravity decreases as the distance between two objects increases.
What is a gravity well?
A gravity well is a model of the gravitational field around a massive body.
Describe an example of gravity in everyday life
An example is dropping a ball; it falls to the ground because of gravity.
Explain how gravity affects tides.
The gravitational pull of the moon causes the ocean tides to rise and fall.
Describe how gravity was tested by astronauts
Astronauts tested gravity by dropping objects on the moon, where gravity is weaker.
Explain a fun experiment to show gravity.
Drop two objects of different weights from the same height to see that they hit the ground at the same time.
Why do planets orbit the sun?
Planets orbit the sun due to the gravitational pull between the sun and the planets.
How would life be different without gravity?
Without gravity, we wouldn't be able to stand, walk, or even breathe the same way.
What role does gravity play in black holes?
Gravity in black holes is so strong that nothing, not even light, can escape from them.
Create a short story involving gravity
Students can write their own short story that includes characters interacting with gravity, such as floating in space or jumping on the moon.
