In this activity you will have to use the gravitational field strength (g) to perform calculations. The value of g is 9.8 N/kg. However, some Physics classes will round g to 10 N/kg in order to shorten the calculating time and complexity with only minimal sacrifices to accuracy. This Concept Builder is equipped to use either value of g … so it’s your choice.
Which value of g do you wish to use?
g = 9.8 N/kg
g = 10 N/kg
