GRAVITY

WHAT IS GRAVITY?

• When you have more matter you get more gravity.
• Mass is the main part of gravity
• Gravity makes everything stay on the ground and not float
• It has a gravitational pull on everything.

Isaac NEWTON

• He first studied gravity when an apple fell on his
• Head while laying on a bench.Then he started wondering why
• Apples fall.Then he was researching about mass and gravitational .
• Basically the first sight and sign of gravity was when an apple fell
• On Isaac newtons head.Isaac Newton and his law of gravitation

WHERE DOES GRAVITY COME FROM?

• Comes from all around us.
• From the Invisible forces .
• Once you are born the invisible forces bound u to earth .

WHAT WOULD HAPPEN IF WE DIDENT HAVE GRAVITY?

• Everything would be going up not down
• Gravity forms stars and planets.
• maintains the suns energy.
• Gravity makes the force around earth .
• No life would be on earth eaither.

WHY DOES EARTH HAVE SO MUCH GRAVITY?

• It is not as close to the sun as
• Mars and mercury.Because when you
• Are by the sun you have less mass.
• So that's why other planets have more
• Gravity then mars and mercury.

WHY DO WE HAVE GRAVITY?

• Because on earth we have mass so therefore we
• Have Gravity.
