I had a question at 18:25 when the car is at the top of the vertical circle, I think the support force should act upwards rather than down if it is in the circle as it needs reaction upwards from the track otherwise the car would just fall and support force will contribute to it. can somebody pls reply quickly as i have an exam tomorrow, thanks

I believe the support force is just the reactive force of the structure onto the car so will act towards the centre due to the track being round

So imagine the diagram of the circle and how the line for the velocity is in a straight line. Due to this line being straight there is a small component of the velocity acting pushing the chair away from its circular path hence why the chair swings are being flung outward.

Is tension centripetal force, or is tension part of the centripetal force equation? For instance, mv^/r = T - mg for a string at the bottom of a circular path.
@ScienceShorts7 жыл бұрын
It's exactly the same as the support force of the track in the last example. For the bottom of a vertically circular path, the tension is solely responsible for the centripetal force, but also has to balance the weight, so T=mg+mv^2/r

a bit late but v= ms-1, if you square that you get m^2 ^-2, dividing it by r gives ms^-2 therefore giving acceleration.
@MrPiinQu7 жыл бұрын
how come at 15:34 you have divided by sin and cos, when Force is usually = cos x Theta not divided?
@ScienceShorts7 жыл бұрын
Because we know that the force responsible for circular motion must be greater than the centripetal force. For example, if centripetal force = 5N, it is impossible for say 3N of upthrust to provide this, which is what multiplying by cos or sin would get you.
@gooddeedsleadto74994 жыл бұрын
direction of resultant velocity would continually change toward the center? But magnitude of the resultant would never change? This means the acceleration would not change & point toward the center? because the velocity is continuously changing the direction & the direction of the resultant velocity remains toward the center, & the rate called centripetal acceleration? Is acceleration defined number of directional changes per unit time in this case?

@namename31302 жыл бұрын
A planes wing doesnt just generate lift in an upwards sense, it creates a force that is always perpendicular to it. In level flight all the force generated by the wing is matching the gravity - mg. But when the plane banks (rolls) the force generated by the wings changes direction accordingly. Also the wings lift changes depending on the application of the ailerons (up + down flight controlls). When the plane is banked the pilot will use the ailerons to increase the lift of the wing allowing for only the vertical component of lift to counter mg and the horizontal to provide the centripetal force. If the pilot didnt use the ailerons mg would be larger than the lift component and the plane would loose height.

Why does the International Space Station orbit the earth every 30 mins and why was a specific speed chosen for it?
@mauricegold93774 жыл бұрын
The ISS orbits the Earth every 90 minutes not 30, at an average altitude of 400 kilometres above the Earth. This was likely chosen as a safe minimum altitude that the Space Shuttle could reach, and that the ISS only required minimal occasional altitude boosts to avoid re-entry. The velocity it has is a function of its altitude. A higher altitude, less velocity. Lower altitude higher velocity. However, there is still some aerodynamic drag on the ISS due to residual atmosphere even at 400 kilometres, so it wouldn't be safe orbiting much lower, as the station is expected to remain in orbit for years, not just mere months.
