All objects are attracted to each other by the force of:

• Gravity 
• Inertia 
• Orbital Speed 
• Terminal Velocity

The strength of the force of gravity depends on:

• the masses of the objects and their speeds.
• the masses of the objects and the distance between them.
• the weight of the objects and their speeds.
• the masses of the objects and their weights.

What did Kepler discover about planets and their orbital speed?

• Planets closest to the Sun will orbit with the fastest orbital speed.
• Planets with the greatest mass will orbit the Sun with the fastest orbital speed.
• Planets furthest from the Sun will orbit with the fastest orbital speed.
• Planets with the least mass will orbit the Sun with the fastest orbital speed.
