[@JoséAntonioBottino]

In a Uniform Circular Motion, the speed v remains constant. If the object makes n revolutions (cycles) in a time t, then it travels a distance s: s = 2 • 𝜋 • r • n and v = s / t = (2 • 𝜋 • r • n) / t Since v = ω • r, then ω • r = (2 • 𝜋 • r • n) / t. This implies that ω = (2 • 𝜋 • n) / t If ω = 2 • 𝜋 • f where f is the frequency, then 2 • 𝜋 • f = (2 • 𝜋 • n) / t. This implies that f = n / t where n is the number of revolutions, n is dimensionless, n has unit rev/rev = 1. Since the period T = 1 / f, then T = t / n. Since the period T is the time it takes for the object to complete one revolution (one cycle), then the unit of T is: s/(rev/rev) = s equal to seconds per number of revolutions (second per number of cycles). Since the frequency f is the number of revolutions (cycles) per unit time (usually seconds), the unit of f is: (rev/rev)/s = Hz = 1/s equals the number of revolutions (number of cycles) per second [nrps = (rev/rev)/s, if you want to keep the custom], and not in revolutions per second (rps). The unit hertz (Hz) replaced the unit cycles per second, which is actually the number of cycles per second. Finally, it is understood that in the formula ω = 2 • 𝜋 • f the unit conversion is 1 (rad/rad) = 2 • 𝜋 • (rev/rev). This confirms the unit of angular velocity ω which is (rad/rad)/s = 1/s.

Such an amzing teacher .you are the brightest light for me in physics . Never get bored after watching your videos

[@cartoonic6039]

I have a very simple but question. Why doesnt the object collapse into the point. Since the centripetal force is an acceleration is increasing with time it should get to a point where its high enough to pull the object towards its centre. For example: The electron in an atom if not for its stationary state it should be pulled towards the nucleus since the proton and nucleus attract but what keeps it moving in a circular path is the fact that they have fixed energy called stationary States so they can't lose energy. But objects in the real world dont have fixed energy level so what keeps them in circular path? Another example is that if we change the mechanics occurring on the body interms of force, The centripetal force will be the F=m×a but converting the objects tangential velocity into force its F=0 since it has no acceleration.Resolving the 2 forces the object is supposed to move towards the center so why does it still move circular

[@codestickyt4695]

Centripetal force is constant. Unless the radius or mass is changed

[@kavitham9208]

If the applied force is constant then the acceleration will be also constant ❤❤❤

[@MickiyasMickiyas-j7w]

You are perfact❤

[@dandarte4062]

Uniform circular motion has no acceleration. There is no linear vector(except in the imagination), therefore no centripetal acceleration or force. The only force acting on the coin is away from the centre and is called the centrifugal force, that at sufficient speed of the table, will cause the overcoming of stiction and then a complete change of mechanism occurs. There are centrifuges manufactured but no centripetal machine exists.

[@JoséAntonioBottino]

Many people wonder why radians do not appear when we have radians*meters. Here is an attempt at an explanation: Let s denote the length of an arc of a circle whose radius measures r. If the arc subtends an angle measuring β = n°, we can pose a rule of three: 360° _______ 2 • 𝜋 • r n° _______ s Then s = (n° / 360°) • 2 • 𝜋 • r If β = 180° (which means that n = 180, the number of degrees), then s = (180° / 360°) • 2 • 𝜋 • r The units "degrees" cancel out and the result is s = (1 / 2) • 2 • 𝜋 • r s = 𝜋 • r that is, half of the circumference 2 • 𝜋 • r. If the arc subtends an angle measuring β = θ rad, we can pose a rule of three: 2 • 𝜋 rad _______ 2 • 𝜋 • r θ rad _______ s Then s = (θ rad / 2 • 𝜋 rad) • 2 • 𝜋 • r If β = 𝜋 rad (which means that θ = 𝜋, the number of radians), then s = (𝜋 rad / 2 • 𝜋 rad) • 2 • 𝜋 • r The units "radians" cancel out and the result is s = (1 / 2) • 2 • 𝜋 • r s = 𝜋 • r that is, half of the circumference 2 • 𝜋 • r. If we take the formula with the angles measured in radians, we can simplify s = (θ rad / 2 • 𝜋 rad) • 2 • 𝜋 • r s = θ • r where θ denotes the "number of radians" (it does not have the unit "rad"). θ = β / (1 rad) and θ is a dimensionless variable [rad/rad = 1]. However, many consider θ to denote the measure of the angle and for the example believe that θ = 𝜋 rad and radians*meter results in meters rad • m = m since, according to them, the radian is a dimensionless unit. This solves the problem of units for them and, as it has served them for a long time, they see no need to change it. But the truth is that the solution is simpler, what they have to take into account is the meaning of the variables that appear in the formulas, i.e. θ is just the number of radians without the unit rad. Mathematics and Physics textbooks state that s = θ • r and then θ = s / r It seems that this formula led to the error of believing that 1 rad = 1 m/m = 1 and that the radian is a dimensionless derived unit as it appears in the International System of Units (SI), when in reality θ = 1 m/m = 1 and knowing θ = 1, the angle measures β = 1 rad. In the formula s = θ • r the variable θ is a dimensionless variable, it is a number without units, it is the number of radians. When confusing what θ represents in the formula, some mistakes are made in Physics in the units of certain quantities, such as angular speed. My guess is that actually the angular speed ω is not measured in rad/s but in (rad/rad)/s = 1/s = s^(-1).
