Uniform Circular Motion
Über den Vortrag
Der Vortrag „Uniform Circular Motion“ von Jared Rovny, PhD ist Bestandteil des Kurses „Force“.
Quiz zum Vortrag
In the equation a꜀ = v²/r , what does v stand for?
- The speed of the object along its circular path
- The speed of the object perpendicular to the circular path
- The speed of the object towards the center of the circle
- The vertical component of the acceleration
- The speed which allows the object to escape a circular motion
An object of mass m has three forces F₁ , F₂ and F₃ acting on it and has a uniform circular motion with speed v. The radius of the circular path is r. Which of the following is an accurate way to write Newton’s second law for this object?
- |F₁ + F₂ + F₃| = mv²/r
- |F₁ + F₂ + F₃| + mv²/r = ma
- F₁ = ma
- mv²/r = ma꜀
- |F₁ + F₂| + |F₃| = mv²/r
Which of the following is TRUE about the acceleration of an object undergoing uniform circular motion?
- It is always directed towards the center of the circular motion.
- It is always directed outwards from the center of the circular motion.
- It is always directed along the direction of the circular motion.
- An object with a uniform motion has no acceleration.
- It is equal to 2v²/r with v being the speed of the object and r the radius of circular path.
