g = 9.8 m/s/s for falling objects on Earth. This means that for every second that passes,

• an object's speed gets faster by 9.8 m/s

• An object has the same speed the whole time it falls - 9.8 m/s

• An object slows down 9.8 m/s when it falls

An astronaut floats away from Earth. The astronaut would weigh LESS because

• the distance between the astronaut and Earth is increasing, and gravity's pull is weaker

• the Astronaut's mass is getting smaller

• there is no gravity when you are in space

Weight is.. (choose all that apply)

• a measure of the force of gravity on an object

• measured in Newtons

• measured in g or kg

• the amount of matter in an object
