not sure if this question has been asked before, but is the weight of an object the same in a vacuum compared to weight in an atmosphere. the concerns of this question is that do we need to consider that our atmosphere provides some boyancy on our mass to change the value of weight.
yes the concept described appears to be simple harmonics when you talk about the period of an oscillation. hmmm, remind me if I'm wrong but mass is not in the period of an ocsillation in simple harmonics
T = 2(pi)(sq. root)(length/g)
As we have been instructed for years that there is no energy that can be obtained (perpetual motion) so how can we expect that the increase of wind power is electrical energy for free? If we use wind to obtain energy will this wind energy loss from our environment have an adverse affect on our...
i believe the sum of the forces applied will compensate the resultant impulse.
m.a = (20 + 40) + (fg + air resistance)
therefore the increased impulse is directly proportional to the increased mass.
yes!
first thing i would look at is the aspect of net forces applied to a mass. Newton's second law f = m.a we note that the net force is directly proportional to the mass therefore the net force may be affected.
m.a = fa + ff
ok, now let's look at impulse. the real question is will the time...
this is a similar question to an earlier queestion but an interesting relationship occured.
when finding an experiemental coefficient of friction between a brick and a wooden ramp we can determine this coefficient by applying a measureable force at a constant velocity and the weight of the...
is this F value you are indicating the net F ? We have a measured value for the force up the incline, how is this value
F = m*g*sinθ + μ*m*g*cosθ
included into my equation to find the coefficient value?
we are conducting a lab where measurement of force on an incline is necessary. the mass which is pulled is a small concrete block (15.8 kg) on a wooden ramp. as the ramp is increased the force changes (increasing) which is expected. last we need to look at the coefficient of friction at...
this may be true, but you also need to consider the net force on the object and thus with an increased mass the force normal at that angle would be higher on the larger mass object resulting in an larger frictional force as long as the force applied are reasonalby the same. I would then have to...
