  1. Centripetal Force. LSWl 3.2-5. The key to imderstanding uniform circular motion is identif)'ing the forces respon­ sible for the centripetal acceleration, and remembering that the centripetal acceler­ ation is always directed toward the centre of the circle around which the object moves.

  2. 3 Μαρ 2024 · Centripetal force is the force that acts toward the center of a circular path. The force is always perpendicular to the direction of movement. The formula for centripetal force is F c = mv 2 /r. The force pushes or pulls an object toward the center of rotation, for example, in planets orbiting the Sun, turning a car, or spinning a ball on a string.

  3. The moon's mass is 7.35 × 1022 kg, and it moves around the earth approximately in a circle or radius 3.82 × 105 km. The time required for one revolution is 27.3 days. Calculate the centripetal force that must act on the moon.

  4. Define centripetal force. Can any type of force (for example, tension, gravitational force, friction, and so on) be a centripetal force? Can any combination of forces be a centripetal force? If centripetal force is directed toward the center, why do you feel that you are ‘thrown’ away from the center as a car goes around a curve? Explain.

  5. What is the centripetal force acting on the car, and which force provides it? 9. A 2.0 kg object is tied to the end of a cord and whirled in a horizontal circle of radius 4.0 m completing 2 revolutions in 6 seconds.

  6. Centripetal Forces Worksheet. 1. A 20 gram ball around in a horizontal circle 80 times per minute if the ball is attached to a 60 cm long string. a) Find the angular speed of the ball. b) Find the force in the string – (assume no gravity). 2. The same ball is now whirled in a vertical circle (now there is gravity).

  7. CENTRIPETAL FORCE. Purpose. To study the characteristics of uniform circular motion. To experimentally measure centripetal force in a circular motion. Theory. When an object of mass M is revolving in a circular motion of radius R, the object is in accelerating motion.
