Question

if you double the mass of an object while leaving the net force unchanged what is the result of the acceleration

Answer 1

Force = mass*acceleration
acceleration = Force/mass

If you double the mass then acceleration will be halved in order for the equation to still equal.

New acceleration = Force/(2)mass
New acceleration = (1/2)* Force/mass------->if you compare this to original acceleration equation above it is 1/2
