Review of motion

The Earth produces its own ________ field.

• spectrum

• electric

• magnetic

• progressive

Every magnet has both a _________ pole and a __________ pole.

• North, South

• East, West

• Positive, Negative

• Positive, South

If two magnets are placed so that two ____________ poles or two ____________ poles are facing each other, they will repel each other.

• North, South

• external, internal

• positive, negative

• North, West

The force that causes objects with mass to attract one another.

• Weight

• Gravity

• Mass

• Magnetism

Any object with mass has gravity.

• True
• Sometimes
• False
• Never

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less 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 closer two objects are to each other

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

Two objects with a greater mass have

• less gravitational force
• stronger gravitational force
• no clue
• a way to break apart

A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity
• Jupiter has less mass, and therefore more gravity
• Jupiter has more mass, and therefore less gravity
• Jupiter has less mass and therefore less gravity
