Did Hooke discover gravity?

Did Hooke discover gravity?

Everyone knows that Isaac Newton came up with the law of gravity after seeing an apple fall from a tree in his mother’s garden. They were penned by his scientific rival Robert Hooke in 1670, decades before Newton started telling people the apple story.

How is Newton derived the law of gravitation?

Sir Isaac Newton’s inspiration for the Law of Universal Gravitation was from the dropping of an apple from a tree. Newton’s insight on the inverse-square property of gravitational force was from intuition about the motion of the earth and the moon.

Who actually found out about gravity?

Sir Isaac Newton
Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.

Who found gravity before Newton?

The Indian mathematician/astronomer Brahmagupta (c. 598 – c.

What is the value of g’on Earth?

9.8 m/s2
In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.

What would happen if gravity wasn’t invented?

Dialing down the scalar field to zero everywhere would essentially flatten the universe. Objects would no longer be drawn toward each other, because there would be no sloping surface for them to fall down. Instead, they would fly off in whatever direction gravity was keeping them from going.

What would happen if gravity wasn’t discovered?

Without gravity, humans and other objects would become weightless. That’s because the planet would continue spinning, without exerting gravity to keep objects tied to it [source: Domanico]. A loss of gravity would also mean that the planet would stop pulling down air, water and Earth’s atmosphere.

Who found gravity India?

In the 7th century, Indian astronomer Brahmagupta spoke of gravity as an attractive force.

How did Einstein prove E mc2?

In his 1905 paper, Einstein examined the change in the translational kinetic energy of an extended body when it emits a pair of light pulses in opposite directions. To determine the implications of this emission process for the rest mass of the body, he needed a definition of the kinetic energy of the body.

Where is gravity strongest on earth?

Lots of places state that the Earth’s gravity is stronger at the poles than the equator for two reasons:

• The centrifugal force cancels out the gravity minimally, more so at the equator than at the poles.
• The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
