The acceleration of any object due to Earth’s gravity is -9.81 m/s2. For every second an object falls, its velocity changes by 9.81 meters per second. For several different times on the table, multiply the time by the acceleration.

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?
