Answer to Question #80204 in Physics for Jackie

Question

given f= ma, f= force, m= mass, and a= acceleration, describe what happens for each situation when the mass of an object remains the same. (mass is the constant of variation)

f increases by 4 times

f decreases by 1/2 times

a increases by 2 times

a decreases by 1/3 times

Answer 1

The Newton’s second law states
ma=f
So, for constant mass
a~f
Therefore
acceleration increases by 4 times
acceleration decreases by 1/2 times
force increases by 2 times
force decreases by 1/3 times
