Force, Mass Accelleration questions (2) Basic stuff!?

Question

1. In order to compare the effects of a changing net force on acceleration, what must be kept constant?

2. In order to compare the effect of changing the mass on acceleration, what must be kept constant?

Thanks!

Answer 1

1. if you are changing Force, and comparing the effect on Acceleration, then the only thing remaining to keep constand is Mass

2. Similarly, all that's left is Force

Answer 2

Force = mass x acceleration. Therefore if the force increases and the mass remains constant then the acceleration will increase.

If the force is kept constant, the acceleration will be that force divided by the mass.

Answer 3

Don't quote me for it, but im almost certain number 1 is mass, because you're looking for changes on the force and acceleration...

and number 2 i think is the force that needs to stay constant, because different masses are going to accelerate at different rates.

hope this helps

Answer 4

while the hammer hits the nut, it decelerates in an particularly couple of minutes from 5m/s to 0. think it does so in 1ms, then the acceleration is -5000m/s^2. this is unfavorable because of fact the hammer is slowing down. a huge impulsive stress is exerted upon the two the hammer and the nut: equivalent forces and in opposite guidelines. you could calculate the stress because of fact the made from the 1kg mass and besides the fact that acceleration you have. the subject in this problem is estimating how long the hammer takes to come lower back to relax. If the nut is squishy then the stress would be under if this is rock reliable.
