Converting Forces from Grams to Newtons
In this section, you will practice converting forces from grams to newtons. Recall that the force in newtons (N) can be calculated using the formula F = m * g, where m is the mass in kilograms and g is the acceleration due to gravity (approximately 9.8 m/s²). To convert grams to kilograms, divide the mass in grams by 1000.
