we are closer to center of sun
we are closer to center of Earth
If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?
Neither, there is no gravity on the moon.
hammer because it has more mass
feather because it has less mass
both will hit at the same time, there is no wind resistance
The force of gravity (mass x gravity) is also known as...
mass
weight
distance
acceleration
Gravity on moon is less than the gravity on earth because
a. moon's mass is less
b. moon's mass is more
c. moon's mass is equal to Earth
d. moon has no mass

If a door was left open between the bedroom (74 degrees) and the living room (68 degrees), what would likely happen to the temperatures after several hours?
nothing, they would not change
both rooms would become hotter

the bedroom temp. would lower and the living room temp. would rise
After holding an ice pack against his skin for 20 minutes, the man notices the ice pack is melting. Why is this happening?
radiation - the ice pack is now all melted
conduction - body heat transferred to the cold ice pack
convection - the water in the ice pack flowed in a circle pattern
conduction - heat came from the bigger object to the smaller

radiation - from the sun is heating the glass
conduction - the table beneath the glass is heating
convection - the air is moving in a circle pattern around
conduction - the straw is heating up
