Defining Gravity

The video explains the concept of gravity, its significance in keeping everything grounded on Earth, and how it was first studied by Isaac Newton. It recounts the famous story of Newton and the apple, illustrating how gravity acts on all objects regardless of their weight. The video also includes a simple demonstration using a tennis ball to show how gravity pulls objects down, regardless of the direction they are thrown.

What is the primary role of gravity on Earth?

• To pull objects towards the ground

• To create wind currents

• To push objects away from the ground

• To make objects float in the air

Who was the first person to study gravity seriously?

• Isaac Newton

• Galileo Galilei

• Albert Einstein

• Nikola Tesla

According to the story, what event led Newton to think about gravity?

• A bird flying overhead

• An apple falling on his head

• A strong gust of wind

• A sudden rain shower

What did Newton conclude about objects of different weights?

• Heavier objects remain stationary

• Lighter objects float upwards

• All objects fall at the same rate regardless of weight

• Heavier objects fall faster than lighter ones

What happens when you throw a ball in any direction?

• It will move upwards continuously

• It will eventually fall to the ground

• It will float indefinitely

• It will disappear
