How could you keep an objects a acceleration the same if the force acting on the object were doubled?

Answer 1

Mass doesn't change. The relative appearance of that mass from the "stationary" observer does. Thus, a bus traveling at 50Mph weighs 20,000lbs, but at 95% the speed of light it's relative mass would be over 100,000 tons to the stationary observer. However, to the person traveling within or alongside the bus at the same speed, it's mass has not changed.

"Changing mass" implies that the object acquires new mass as it travels faster, which it cannot. It simply "appears" to change mass.

Answer 2

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

Answer 3

Change the environment the object is moving through. For instance, powering a boat through mud is slower than water which is slower than air (drop from a plane)

Answer 4

Create an equal force on the opposing side to balance out the doubled force so that it will remain at the same level of acceleration

Answer 5

Force is mass times acceleration. If the force is doubled, then the mass must be cut in half to keep the acceleration the same.

Answer 6

You can't. The acceleration is equal to the force divided by the mass; since you basically can't change the object's mass, the acceleration - for a given object - depends only on the force.

Answer 7

Sit a rock on it.
