What happens to acceleration if both mass and force remian constant?

Answer 1

Since acceleration = force / mass, it will fall as mass increases.

Progressive loss of mass is much more likely to occur in real life - for instance with a rocket, which burns fuel as it goes. In this case, acceleration will increase.

Answer 2

Since the mass is constant, acceleration will increase linearly with the force applied.

This describes the ordinary non-relativistic situation described by Newton's 2nd law of motion, F=MA, or for this purpose: A=F/M

Answer 3

Newtons second Law says that F = M x A
That is; force is equal to mass times acceleration.
So, if an identical force is applied to two objects, one twice as heavy as the other, the light one will accelerate away twice as fast as the heavy one (ignoring trivialities such as friction and wind resistance)

In other words, if the force remains constant, a body's acceleration will decrease if its mass increases.

Answer 4

From the equation F=ma you can determine that force and acceleration are directly related. If force increases, acceleration must also increase by the same factor; for example, if you double the force, the acceleration will also double, provided the mass is constant.

Answer 5

Newtons second law of motion is basically F=ma. If you rearrange this to equal acceleration you get a=F/m. If the mass remains constant there will be no change in acceleration unless a force is applied. Because the applied force is increasing and acceleration is proportional to force the acceleration also increases

Answer 6

If the object was at constant velocity when the net force increased, then it will start to accelerate. If the object was already accelerating when the net force increased, then it will experience an increase in acceleration.

Answer 7

In Newtonian physics, force (F) is proportional to the mass (m) multiplied by the

acceleration (a): F= m*a. The question goes on to specify constant force and

increasing mass. Mathematically, this means decreasing acceleration. You will stop

soon.

==================================

Answer #2:

I can't imagine how you could increase the mass of a moving object, but . . .

The acceleration is directly proportional to the net force, and inversely proportional

to the mass. So if the force is constant and the mass changes by some factor, then

the acceleration changes by 1/the same factor . If the mass is increasing then the

acceleration is decreasing.

A rocket just after launch is the opposite situation . . . The rocket motors are

exerting a constant net force, but the rocket's mass is decreasing because the

fuel load is being burned. The rocket's acceleration increases as the fuel load

decreases. (And also because the force of gravity on it is decreasing as it gains

altitude, but that's another story.)

P.S. Returning to the punch-line in Answer #1 . . . There's no reason why you will

"stop soon". As long as there is a net force acting on you, your acceleration will

never become zero, no matter how large your mass becomes so long as it remains

finite. And even if the acceleration did become zero, that doesn't mean that you

would stop, only that your speed would stop increasing.

Answer 8

Fuel is used faster in larger cars than smaller cars if they will be having larger holes and fuel is lost through that hole

The chemical energy will be converted into kinetic energy and that is why cars are moving and they will be having more kinetic energy

Answer 9

If you double the mass then the acceleration is halved, with the same force.

Answer 10

Providing it is exactly the same the object's acceleration stays the same. If there aren't any other forces acting against it newtons laws of motion state that it will go on forever
