Note from the author:

A football coach wants to figure out which of his players can push a tackle sled with the most force. 

Plan an investigation that will help the coach. Be sure to address the questions below and include everything that needs to be measured and calculated before, during, and after his players run the drill.

Here is some data about the players:
Player           Weight         Speed (meters   in 10 seconds)   
Player 1        80 Kg           32 meters   
Player 2       100 Kg          25 meters   
Player 3       75 Kg            40 meters   
Player 4       95 Kg            35 meters

Which diagram best models the force(s) being applied to the tackle sled in the investigation?

What are the independent variables (What is changed on purpose)?

force applied to sled, length of the field

mass of player, acceleration of player

mass of player, mass of sled

mass of sled, acceleration of player

What are the dependent variables (What we are measuring)?

Force applied to sled

Mass of player, mass of sled

Distance the sled moves.

Distance sled moves, mass of sled

What are the controlled variables (Things that stay the same)?

length of field, players speed, wearing cleats

mass of sled, wearing cleats, length of field

players speed, length of field, mass of sled

players speed, wearing cleats, mass of sled

What information would you need to successfully solve the coaches problem (Choose all that apply)?

Which data table would be most helpful to record the data collected during the investigation?
