I'm doing a lab where I had to use a cart and a pully, collecting data to compare the net force and the acceleration and again for acceleration vs mass. The acceleration vs mass graph was a curve, which we then straightened out to give us a graph of acceleration vs 1/mass. I am wondering how i...
They need help understanding the accepted values and percent errors for the velocity and they don't know where to find the information. They attempted to attach the equations from class but they don't seem to work. They are also having trouble working out the percent errors.
I have this question for homework and I'm well stuck! The specific heat capacity of a liquid was found by heating a measures quantity of the liquid for a certain length of time. The following results were obtained. Power of heater: ( 50.0 ± 0.5)W Mass of liquid: (200 ± 10)g Time of heating...
The equation for acceleration error, a = 2h/t^{2}, is based on the assumption that acceleration is constant. Therefore, it may not be applicable to scenarios where acceleration is not constant, such as in cases of changing velocity or acceleration due to external forces.
part b says derive the equation for a in the form a = F/m (f and m in terms of forces and messes in the ...
Mentor Note -- Thread moved from the technical forums, so no Homework Template is shown. So, we've conducted an experiment on resistors in a circuit. The theoretical calculation was based of on E-24 series color band table and the measured resistance of the resistor was measured by a meter...
In summary, To calculate the % change in momentum of a lorry traveling at a constant velocity of 13.41m/s from loaded to unloaded, you need to use the equation change = momentum_full - momentum_unloaded = v(m1-m2) and then use the formula percentage change = (change / momentum_full) * 100%.
Or since it's both +/- 1 degree, do you also do another equation multiplying by a negative pi/180 ...
Homework Equations Ki = 1/2mv^2 Kt = Ki + Kf The Attempt at a SolutionI think that the 93% is the amount lost in kinetic energy, but I am not sure.
Homework Statement There are two equations from which change in gravitaton potential energy of a system can be calculated. ΔEg = mgh and the other Eg = GmM/R The first equation is only correct if the gravitational force is constant over a change in height h. The second is always correct...
