@mensurmehmedagic8751 Well, my physics 1 teacher kind of sucked (no one in my class got above a 2 on the test). I think the hardest thing for me was contact forces, torque, and gravitation. Right now, I'm in physics C and it's not as bad with a better teacher.

you dont realize how much all your videos have saved me in physics for my grade 12 year. My friends and I all joke in class about how we're going to have to watch your videos since we can't understand whats really going on, so thank you !

The first part of this video helped me understand an extra credit question in my Geog605 class, remote sensing of the environment. We were asked how many times a certain satellite would orbit the earth in a day and we were only give the satellite altitude, earth's mass and radius, and the gravitational constant. The essential piece of missing info was the equation for the distance of a circular path. One question though, how did you translate your velocity value into m/s?

Extremely helpful 👍🏻

Sir, how you can cancel both R, In centripetal Force R is the radius of circle(i think it should be the distance between Surface of Earth and Satellite) and in Gravitational Force R is the separation between two masses (from center of Earth to the Satellite). Could you Please Explain

when do we use m/s and km/s when solving for velocity?

I enjoy this wonderful lesson from tanzania

I am in 9th grade and u made this soo easy

Tysm bro

This wonderful

while on a circular orbit if the velocity of the object is increased then it will go further away but a new balance can be achieved only if distance decrease. (Higher velocity means higher centrifugal force and it can be balanced only by a higher gravitational force which will happen only if distance decrease) in reality an elliptical orbit is created. how do you explain this by the above simple physics?

Isn't v the tangential velocity? So shouldn't T = 2pir/v/r since v/r = w which is the rotational velocity?

can u plz explain the variation of centripetal accl. and velocity of planets at different distances from sun?

He used the equation: v=square root (GM/r). This will give you the speed of the satellite which is in circular orbit. If it was in an elliptical orbit, you'd have to use a different equation.

I know I'm really late but in a circular orbit, the object is moving at a constant velocity. in elliptical orbits, the speed varies according to Kepler's second: faster when it is closer to the object the satellite is orbiting and slower when it is further away

@homeofsports3295

3 жыл бұрын

As far as I'm aware the radius of the earth doesn't change, so 6.38x10^6 meters or 6371 kilometers should be a constant. edit : "The scientists estimated the average change in Earth's radius to be 0.004 inches (0.1 millimeters) per year, or about the thickness of a human hair, a rate considered statistically insignificant." *Source : NASA* (www.nasa.gov/topics/earth/features/earth20110816.html#:~:text=The%20scientists%20estimated%20the%20average,a%20rate%20considered%20statistically%20insignificant.) edit 2 : at this rate of 0.1 milimeters per year, it would take 10 milions year just for the radius to go up by 1 kilometer, so I would say 6.38x10^6 meters or 6371 kilometers is good enough

Forces only do work if they have some vector component along the path of motion. This path of motion is the circular orbit, the force is the centripetal force directed towards the center of the Earth. These are perpendicular, so gravity does no work. It's a similar story for charged particles moving in a mass spectrometer, if you've seen that.

@rye-bread5236

if the earth is inside the system it cannot do work. hence 0. If it is outside the system like external forces. it does work. my prof has us set it up like so work= change in energy work= PE + KE ... on the left is external forces that create work (b0th pos. and neg. work has to be parallel though. Work that is perpendicular is 0. Torque is when there are perpendicular force and distance ) on the right is internal energies, Gravitational potential and kinetic. If 0 work that means the internal forces are equal and opposite (for this scenario) Hope this helps.

I keep getting 6.2543E10 for the speed on my calculator. I was wondering what am I doing wrong? I did convert the km into m by multiply it by 1000 and got the same radius in the video. I plugged the exact number in also.
