Acceleration remains the same. Remember that Force equals Mass times Acceleration, or Acceleration equals Force divided by Mass. So, if both Force and Mass double, Force Divided by Mass remains the same.
The acceleration is multiplied by four. a = F/m
force = mass x acceleration so if force doubles acceleration doubles to 8 m/s2
force = mass * acceleration if force is doubled, mass needs to be doubled to keep the same acceleration example: force = 6 mass = 2 acceleration = 3 6 = 2 * 3 12 = m * 3 12/3 = m 4 = mass
The force equal mass times acceleration, if force remains the same, and mass is doubled, then acceleration must be cut in half.
F=ma, if "a" doubles and "m" is the same, the resultant "F" will double. Acceleration is doubled if force is doubled, a1=f/m; a2= 2f/m= 2a1.
By F = ma, if the force remains constant, and the mass decreases, this would mean that the acceleration has increased by exactly the same factor as the decrease in mass. That is, if the mass of a substance was halved, its acceleration would have doubled exactly.
also doubled as long as mass is not changed: F = m a force and acceleration are directly proportional, with mass being what is called the proportionality constant. If mass is not changed, as you can see from Newton's second law to preserve the equality if force increases, the acceleration must increase.
Doubled.
It would depend on what force is driving the acceleration. If that force is gravity, then acceleration is constant irrespective of variations in mass. All else being equal and presuming the acceleration is by the same exerted force on both the larger and smaller object, the larger object would experience 1/3 the acceleration. (The formula for determining the force is F = ma , the mass times the acceleration. For the same F, and m2 is 3m, then a2 must equal a/3. )
The acceleration of an object is proportional to the net force acting on it. So if the force is reduced by half, the acceleration will also be halved. Of course, it will still be accelerating in the same direction as before, but not as quickly.
As force of gravity is directly proportional to the mass as mass is doubled then force on it also gets doubled.
The force also increases.
