AI Thread Summary
Power provided at a constant rate to an object does not result in constant acceleration due to the relationship between power, work, and force. As power is defined as the rate of change of work, it varies over time, leading to an increase in work done on the object. This implies that the force acting on the object, calculated as force equals mass times acceleration (f=ma), changes as energy is applied. Additionally, the discussion notes that this analysis assumes the object has not reached terminal velocity. Therefore, the acceleration of the object remains non-constant as energy and work change over time.

Homework Statement


Power is being provided at a constant rate to an object. Suggest why the accelration of the object is not constant.


The Attempt at a Solution



power is defined as the rate of change of work

P=W/T

Power is changing with respect to time. This increases the work done by the object. Since work done=fs (f=ma)
The acceleration is not constant.

Are my points valid or wrong

Power is changing with respect to time.
Perhaps it would be better if you reworded your answer.
 
ok so energy is changing with respect to time ?

Much better :approve: This of course assumes that the object has not reached its terminal velocity.
 
since energy=work done
and workdone=fs
the acceleration of the object is not constant

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
