Instead of doing 'big jumps', if you could do a relatively large fall from a ledge, like a drop-off. You could do a simple projectile motion physics experiment?
Even if the fall is 1m, you could measure the distance you travelled, then convert that into your various velocity components etc.
The problem which I need help with is this, I've done an experiment in which there is a ramp. This ramp has a stationary ball bearing (B1) of mass (m) on it at a point, h. and there is another ball bearing (B2) at the lowest point of the ramp, of mass (m). Ball bearing (B1) is then released from...
If i cancle the kg out, then i am stuck with a '2' in the final equation instead of a kg unit. because if i try cancle the 2 out by halving that side, then the other side (left hand side) gets 2 in the denominator :/
Vt = (2mg/pA)1/2
Vt = Terminal Velocity (ms-1) as velocity = s/t = m/s(seconds, not distance).
m = mass in kg.
g = gravity in ms-2.
p = fluid density in kgm-3
A = Area in m2
Show that equation is dimesionally correct.
I seem to get my answer wrong on the end product; ill...
I just need some help understanding inertial frame of reference, is this when there is no acceleration acting on a body. such as, gravity.. but the body can be under constant velocity or at rest. Also, Could someone please help me with this senario: there is a guy in a rocket...
Hi all. I'm just wondering if it is possible to calculate the resistance in a coil without the amperage value? i've got voltage,coil-diametre, amount of turns, coils material type.
The only way i think it is possible if i set a ampmetre into the circuit. is there any way?
Hi all. I'm just wondering if anyone can give me some simple plan to make an electric motor?
The materials i have atm are:
2 x Perm magnets
2 x batteries
2 x aligator clips
2 x stands for the coil/armature to sit in
1 x various tools.
I need to be able to attach a string to the...
Hi. Im just wondering if I was going to attempt to find the coefficient friction of a book resting on a block off wood. How would I go about it?
The horizontal distance is 15cm and the vertical distance is 6cm. Would i just do trigonometry to find the...
2. Using your knowledge of circular motion and gravitation, derive an equation that shows the relationship between the orbital period (T) of a planet in a circular orbit and the radius of the planetary orbit (R).
4pi^2/GM = T^2/r^3
39.478/ 3.247E+14 = 1.08E+11/ 7.474E+21
1.215E-13 = 1.445E-11...
That's what i meant sorry, wouldn't that be like: F = 5*(mg) ? but then 2nd law says that if the force is 5 times as much, the acceleration will be directly proportional, therefore 5 times as great. So i thought that becase mv2/r = 5*mg and mass cancles out, so, v2/r = 5*g therefore r = v2/5*g ...
Hey inutard, Thanks for the information on the max Nforce, didnt know that! Okay, because the question states that the max force is 5times the pilots mass i would have thought that it means that the normal force is 5 times greater, and what this means to ME is that it is 5g's. therefore when...
