## What happens to the strength of the gravitational field at the surface of a star that shrinks?

gravity) around an object instead of gravitational attraction as Newton saw it. What happens to the strength of the gravitational field at the surface of a star that shrinks? radius half the size as before will have a gravitational field 4 times as strong at the surface.

## How does the brightness of light change when a point source of light is brought twice as far away?

How does the brightness of light change when a point soure of light is brought twice as far away? If its twice as far the light will be twice as bright. At what distance from earth is the gravitational force on an object zero? No matter how far away, the earth’s gravitational force approaches, but never reaches zero.

## What connection did Newton make between a falling apple and the moon?

Terms in this set (5) what connection did newton make between a falling apple and the moon? newton reasoned that the moon is falling for the same reason the apple is falling. They both are being pulled by earths gravity.

## Which pulls with the greater force on Earth’s oceans?

The moon’s gravitational pull is the primary tidal force. The moon’s gravity pulls the ocean toward it during high high tides. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet.

## Where on Earth’s surface is gravity the strongest?

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.

## What is value of G?

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. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

## Is luminance dependent on distance?

And Luminance is a property of a light source; so it does not vary at all, with distance from the light source.

## What is the relationship between mass and distance?

Newton’s law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them.

## What is the mathematical relationship between the intensity brightness and distance to the source of light?

The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. Suppose you were to use a light meter to measure an initial intensity Ii, or brightness, a distance r from a light source.

## What did Newton say when the apple fell?

-an apple hits him on the head. “Aha!” he shouts, or perhaps, “Eureka! ” In a flash he understands that the very same force that brought the apple crashing toward the ground also keeps the moon falling toward the Earth and the Earth falling toward the sun: gravity.

## Why do we not see earth moving towards the apple?

According to the third law of motion, the apple does attract the earth. But according to the second law of motion, for a given force, acceleration is inversely proportional to the mass of an object. So, we do not see the earth moving towards the apple.

## Can you name the three laws of motion?

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction.

## What keeps the oceans in place?

As gravitational force acts to draw the water closer to the moon, inertia attempts to keep the water in place. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge.

## What is the greatest contributor to tide generation?

What is the greatest contributor to tide generation? Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

## What are the 4 types of tides?

The Four Different Types of Tides

• Diurnal Tide. ••• A diurnal tide has one episode of high water and one episode of low water each day.
• Semi-diurnal Tide. ••• A semi-diurnal tide has two episodes of equal high water and two episodes of low equal water each day.
• Mixed Tide. •••
• Meteorological Tide. •••
