Two large rocks, a 1,000 kg rock and a 500 kg rock, are rolling downhill. According to Newton's 1st Law, which rock has more inertia?

• The 1,000 kg rock

• The 500 kg rock

• They have the same amount of inertia

• There's not enough information to answer this question

After bringing a scale to the moon, the astronaut discovers they have a lower weight than they do on Earth. Why is this the case?

• Because gravity is higher on the moon

• Because the moon is larger than the Earth

• Because gravity is lower on the moon

• The scale is broken; your weight is the same everywhere

Newton's First Law States:

•  $F\ =\ ma$  

• For every action, there is an equal and opposite reation.

• An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.

Newton's Second Law States:

•  $F\ =\ ma$  

• For every action, there is an equal and opposite reation.

• An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.
