What is Gravity
What is gravity?
The force that pulls objects toward each other.
What happens if you drop an apple and a pencil at the same time?
They fall at the same speed (if there's no air resistance).
True or False: Gravity works in outer space.
True
What force slows a ball down after it’s thrown into the air?
Gravity.
What object has the strongest gravitational pull in our solar system?
The Sun.
Why do astronauts float in space?
Because they are in free fall, falling around the Earth.
True or False: A heavier object falls faster than a lighter one.
False – they fall at the same rate (if no air resistance).
What would happen if you threw a ball in space where there is no gravity or air?
It would keep moving in a straight line forever.
Who discovered that gravity is a force that pulls objects to Earth?
Isaac Newton.
What keeps the planets in orbit around the Sun?
The Sun’s gravity.
True or False: Gravity only works on Earth.
False – gravity is everywhere.
Why do objects bounce less and less after each bounce?
Gravity pulls them down and some energy is lost on impact.
Why do things fall to the ground instead of floating away?
Because Earth's gravity pulls them down.
What causes ocean tides on Earth?
The Moon’s gravity.
True or False: You don’t have gravity inside your body.
False – all matter has gravity, even you!
What causes a roller coaster to come back down after going up a hill?
Gravity pulls it downward.
What would happen to your weight if you went to the Moon?
You would weigh less because the Moon has less gravity.
If you jump up, why do you come back down?
Gravity pulls you back to Earth.
True or False: Gravity is weaker the farther you are from Earth.
True.
What is the invisible area around a planet or star where its gravity can pull on objects?
A gravitational field.
