Question

when there is an increase in mass of an object you will have a decrease in _____________. gravity acceleration force friction

Explanation:

To solve this, we refer to Newton's second law of motion, \( F = ma \) (where \( F \) is force, \( m \) is mass, and \( a \) is acceleration). If force (\( F \)) is constant, and mass (\( m \)) increases, then acceleration (\( a=\frac{F}{m} \)) must decrease (since \( a \) is inversely proportional to \( m \) when \( F \) is constant). Gravity is related to mass but an increase in an object's mass doesn't decrease gravity in this context. Force would increase with mass (if acceleration is constant), and friction generally increases with mass (for sliding friction, \( f = \mu N \), and \( N \) (normal force) is related to mass). So the correct term is acceleration.

Answer:

B. acceleration
