Gravity is the force that pulls objects together.

Everything that has mass has gravity.

The more mass an object has the stronger the force of Gravity.

The closer you are to an object the more powerful the force.

Weight and distance

Multiple Choice

Name one way to increase the gravity between objects.

Increase distance

Decrease distance

Decrease volume

Remove atoms

Multiple Choice

Where is the planet moving faster?

impossible to know

Multiple Choice

The picture shows the gravitational field in the space surrounding the Earth. What is creating this gravitational field?

The gravitational force.

The mass of the Earth.

The distance of the Earth.

The universal gravitational constant.

Multiple Choice

What is the definition of an ellipse?

All points equidistant from a single point.

All points that are equidistant to the sum of the distance between two points.

All points equidistant to the difference of the distance between two points.

All points equidistant to the sum of the distance between a fixed point and a line.

Multiple Choice

What is the physical reasoning behind Kepler's 2nd law (equal areas in equal times)?

Gravity is weaker as the distance between objects increase, and is stronger as they move closer together.

The sun is pulling the sattelite forwards in the orbit as it moves closer, and pulls backwards as it movevs away.

Because calculus.

The sattelite is pulling on the sun with an equal and opposite force.

Multiple Choice

Earth's orbit follows an elliptical path.
