1,2 A 10 N falling object encounters 4 N of air resistance. What is the magnitude of the net force acting on the object. What is 6 N?

1,3 A force which is always in the opposite direction compared to an object’s motion. What is friction?

1,4 If a baseball player bats a ball with a force of 1000 N, the ball exerts a _____reaction force against the bat. What is 1000 N?

2,1 Your gravitational attraction to the earth is a measure of your _____. What is weight (or gravitational force)?
