Aforce exerted on an object produces acceleration. if the mass remains the same and the acceleration is doubled, the force must be .

The force will be doubled.

Using Newton Law II,

So it can be seen in the formula that force is directly proportional to mass and acceleration.

if mass is doubled ---> force will be doubled, keeping acceleration constant.

Similarly,

if acceleration is doubled ---? force is will be doubled, keeping mass constant.

It is assumed that there is no friction, the object is in the air with no air resistance.

false

explanation:

boats, things on boats luggage are way more heavy then water.
