Gravitation Assessment Alternative

What states that "every object in the universe attracts every other object"?

• Law of Universal Gravitation

• Newton's First Law of Motion

• Conservation of Momentum

• Inertia & gravity

Two factors effecting the magnitude of the force of gravity between 2 objects are...

• mass and distance 
• mass and matter
• distance and weight 
• weight and mass

The law of universal gravitation is credited to whom?

• Newton

• Da Vinci

The definition of gravitational field strength is:

• The region of space surrounding a body where other bodies will feel an attractive force due to it.
• The region of space surrounding a body where other bodies will feel an repulsive force due to it.
• The region of space surrounding a charge where other charges will feel an attractive force due to it.
• The region of space surrounding a charge where other charges will feel an repulsive force due to it.

How far out from a mass should the gravitational field lines go....

• to where the gravitational field becomes negligable
• to twice the diameter of the mass
• infinitely far
• to four times the diameter of the mass

The closer two objects are to each other

• the harder they will land
• have no gravitational force
• have a stronger gravitational force
• yep

What best describes the mass and weight of a person as they move around the universe?

• mass and weight changes
• Mass and weight stays constant
• weight remains constant, mass changes
• Mass stays constant, weight changes

What force keeps objects in our solar system orbiting our Sun?

• push
• gravity
• motion
• pull 

Which of the following best explains why a person has less weight on top of a mountain?

• They are closer to space.

• The atmosphere is lighter.

• The mountain adds more mass.

• The mountain adds more distance.
