Which of these would you expect to require the most force increasing acceleration of a small mass or decreasing acceleration of a small mass?

Any amount of force, no matter how large or small, will increase or decrease the
speed of any mass, no matter how large or small.
But if you specify how much you want the object's speed changed and how quickly
you want it done, then you have specified the acceleration you want. In that case,
the larger the mass is, the more force it will take to accomplish that assignment.

Would you expect to require the most force?
Absolutely. Always assume the worst.
How does temperature affect metals?
Temperature affects metals in several ways:they expand with increasing temperaturetheir electrical resistance changes - we expect their resistance to increase with increasing temperaturetheir mechanical properties (such as ductility, hardness. tensile strength, yeild stress, etc) change - for example usually becoming softer and more ductile with increasing temperaturesome metals will undergo solid state phase changes with changes in temperature - especially alloys
Why you have second square in the unit of acceleration?
Square seconds, by itself, doesn't make much sense. On the other hand, please note that acceleration is not the same as speed or velocity, therefore you would expect the units to be different between the two. Speed or velocity is measured in meters / second; since acceleration is the change of rate of a velocity (in symbols: dv/dt), its units are velocity / time. Using SI units, that would be (meters / second) / second, and this is commonly written as meters / second2, which makes sense since the seconds appear twice in the denominator.
Why does mass of a body vary with velocity?
Here's one way of looking at it: you have to consider the problem from two different frames of reference. Let's set one as a spaceship accelerating at some speed above 0.5c. The other will be a rest frame, the inertial frame from which the ship departed. Each frame contains an identical clock. Each clock, tested before separation, ticks off identical seconds. If I send the ship out and back at high acceleration, then compare the elapsed time on both clocks, I will find that the times vary. Seconds on the moving clock were stretched when compared with those of the rest clock, though time appeared to pass normally on the ship. Consider all of this in terms of fuel consumption. From my frame of reference within the ship, all clocks run normally, so I register a constant fuel consumption for what I expect to be constant acceleration. But from the external (rest) frame, I can calculate that the moving clock has stretched each second in proportion to each increase in speed by the Lorenz time dilation factor, so I record the ship's fuel consumption as being stretched over longer and longer intervals as the ship accelerates. In fact, what is perceived in the ship as constant fuel usage appears to be decreasing usage from the rest frame. It will take longer and longer intervals (or an increasing rate of fuel consumption) to accomplish each increasing increment of velocity as the same amount of energy is expended over increasing intervals. From the ship, I see progressively smaller increases in velocity from the same rate of fuel expenditure. By any method of measurement, this equates to an increase in mass. It appears to take progressively more energy to accelerate the ship by any given increment.
Which of these would you expect to require the most force?
increasing acceleration of a large mass
What kind of changes would you expect to see in an ecosystem over time?
you would expect that the populations of animals are increasing or decreasing or because of no rainfall the plants will get dried.
What do you expect the value of the acceleration of gravity to be?
9.81
Does a radio require radiation?
Only if you expect to hear anything on it.
Would you expect to require the most force?
Absolutely. Always assume the worst.
How fast does a 6.5 hp engine run with 200 lbs?
Depending on the gears used, it can run as fast as you want, dont expect good acceleration tho, unless the gear ratio is ment for acceleration and not speed.
Why are gas prices increasing but the cost per gallon oil is declining?
ummm why do u expect me to know if you don't
What benefits should I expect from a decreasing term life insurance policy?
A decreasing term life insurance policy has the benefit of lower premiums. It also can be adjusted to provide exactly what coverage is needed (for example to cover a mortgage as the total amount due decreases over time).
When heart attack occurs heart tissue enzyme begin to show up in the bloodstream on the third day physicians expect to find what?
Physicians expect to find increasing levels of lactate dehydrogenase (ldh).
What is the difference between the words anticipate and expect?
Anticipating something means to both to expect something and take action for that reason. Expecting something does not necessarily require any action.
What shape do you expect for a graph showing the position of a motorcycle versus time if the motorcycle is speeding up with a constant acceleration?
The position versus time graph is parabolic.
Cosmologists expect the universe to?
They expect the Universe to continue expanding. Right now, the evidence is that the expansion is speeding up. They also expect entropy to continue increasing, so in the distant future, there will not be any free energy left to support life, for example. They also expect quite a few other things; the Wikipedia article on the "future of the Universe" can give you some ideas.
