Gravity!

Interactive Lesson on Gravity and What we have earned so far and what we should know!

What is Gravity?

• the force by which a planet or other body draws objects toward its center.

• ALL matter that has MASS or ENERGY has Gravitational Pull

Poll

What makes an object have stronger gravitational pull?

• it's size: if the object is large

• it's mass: if it's heavier

• it's distance from another object

What makes Gravitational Pull Stronger?

Mass, Distance, and Size

Mass

As the mass between two interacting objects increases, the gravity will also increase.

Distance

As the distance between objects decreases, or get closer, the gravity between the objects increases.

Multiple Choice

If the distance between the objects INCREASES and gets further apart, the gravity will:

• Increase

• decrease

• stay the same

Multiple Choice

If the distance between objects DECREASES and they get closer together, the gravity will:

• increase

• decrease

• stay the same

The Law of Universal Gravitation

gravitational force between masses decreases with the distance between them, according to an inverse-square law. In addition, the theory notes that the greater an object's mass, the greater its gravitational force on another mass

Multiple Select

Check ALL the statements that are TRUE about gravitational pull!

• The smaller the mass the LESS gravitational pull an object has

• The closer objects are the LESS gravitational pull an object has

• The closer objects are the MORE gravity there is

• The larger the mass the MORE gravitational pull it has
