Want this question answered?
the velocity is decreased
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
A 20-newton force would cause acceleration at 6 m/sec The acceleration is given by the formula F=ma (Force = mass x acceleration) so for the same mass, doubling the force doubles the acceleration for the same mass.
If both the mass and the net force on an object are doubled, then the object's acceleration will not change.
the velocity is decreased
Just the opposite. It will cause the acceleration to drop by 50%.

The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.

As mass increases acceleration decreases.
If the mass of an object increases, what happens to the acceleration?
