61
A water drop has 3 parts (2 parts hydrogen and 1 part oxygen). How many parts are there in 5 drops of water?
15 parts
What weighs more a pound of cotton or 3 pounds of iron?

35
A bottle has 10 parts of air. If 4 parts escape, how many parts of air are left?
6 parts
A ball has a speed of 3 m/s. After 4 seconds, how far did the ball travel?
12 meters
Because distance = speed x time

40.5
If 1 drop of water has 2 hydrogen parts, how many hydrogen parts are in 7 drops?
14 parts
Will a ball of mass 5 kg weigh more on the moon or on the earth? HINT: weight (W) = mass (m) x acceleration due to gravity (g) where g is larger on Earth than on the moon
On the Earth
Because W = mg, mass is the same, and g is larger on Earth than on the moon
A rocket needs 500 pounds of fuel for every 10,000 miles it travels in space. If the Moon to the Earth is 240,000 miles, how much fuel is needed to get to the Moon from Earth?

5 parts
If a car is dropped from a height of 100 m, and a ball is dropped from a height of 200 m, which would hit the ground first? HINT: you can solve without the equation: change in height = (1/2)gt^2, g = 10 m/s^2, and t is time in seconds
The car would hit the ground first
Because weight does not play a factor is position vs. time, so being released from a higher height, the ball takes more time to hit the ground
An astronaut weighs 180 pounds on Earth. They travel to a planet with only half of Earth’s gravity. What is their weight on that planet?
90 Pounds
