All flashcards

Flashcard 1: Find frequency: $T=0.1$ s.

Answer: $10$ Hz. Using $f = 1/T = 1/0.1 = 10$ Hz.

Flashcard 2: What is the relationship between period and angular velocity?

Answer: $\omega = \frac{2\pi}{T}$ . One complete revolution takes period $T$ .

Flashcard 3: Identify the force responsible for circular motion.

Answer: Centripetal force. Net inward force maintains circular path.

Flashcard 4: Calculate period: $f=0.5$ Hz.

Answer: $2$ s. Using $T = 1/f = 1/0.5 = 2$ s.

Flashcard 5: Calculate frequency: $T=0.25$ s.

Answer: $4$ Hz. Using $f = 1/T = 1/0.25 = 4$ Hz.

Flashcard 6: What is centripetal acceleration?

Answer: Acceleration directed towards the center of circular path. Always points inward, creating circular motion.

Flashcard 7: What is angular velocity?

Answer: Rate of change of angular displacement. How fast angle changes with time.

Flashcard 8: Define period in circular motion.

Answer: Time to complete one full revolution. Complete cycle duration in circular motion.

Flashcard 9: State the formula for angular displacement.

Answer: $\theta = \omega t$ . Angle equals angular velocity times time.

Flashcard 10: State the relationship between period and frequency.

Answer: $T = \frac{1}{f}$ . Period and frequency are reciprocals.

Flashcard 11: Calculate tangential velocity: $r=3$ m, $\omega=2$ rad/s.

Answer: $6$ m/s. Using $v = r\omega = 3 \times 2 = 6$ m/s.

Flashcard 12: What is the relationship between tangential speed and radius?

Answer: Directly proportional. Larger radius gives higher tangential speed.

Flashcard 13: Identify the cause of centripetal acceleration.

Answer: Change in direction of velocity. Velocity direction changes continuously in circles.

Flashcard 14: Define radial acceleration.

Answer: Acceleration towards the center of circular path. Same as centripetal acceleration definition.

Answer: $12$ N. Using $F = ma = 3 \times 4 = 12$ N.

Flashcard 16: State the formula for angular velocity.

Answer: $\omega = \frac{\Delta\theta}{\Delta t}$ . Change in angle divided by time interval.

Flashcard 17: Calculate centripetal force: $m=2$ kg, $v=3$ m/s, $r=1$ m.

Answer: $18$ N. Using $F_c = mv^2/r = 2(3^2)/1 = 18$ N.

Flashcard 18: Describe the relationship between frequency and angular velocity.

Answer: $\omega = 2\pi f$ . One revolution equals $2\pi$ radians.

Flashcard 19: Find the period given frequency of 2 Hz.

Flashcard 20: State the formula for centripetal force.

Answer: $F_c = \frac{mv^2}{r}$ . Newton's second law applied to circular motion.

Flashcard 21: What is uniform circular motion?

Answer: Motion in a circle with constant speed. Constant speed but changing direction.

Flashcard 22: What is the unit of angular velocity?

Answer: Radians per second (rad/s). Standard unit for rotational speed.

Flashcard 23: Define angular displacement.

Answer: Angle through which a point or line is rotated. Measures rotational position change.

Flashcard 24: State the formula for centripetal acceleration.

Answer: $a_c = \frac{v^2}{r}$ . Speed squared divided by radius gives centripetal acceleration.

Flashcard 25: What is the direction of centripetal force?

Answer: Towards the center of the circular path. Always points inward to maintain circular path.

Flashcard 26: Define frequency in circular motion.

Answer: Number of revolutions per unit time. How many cycles occur per second.

Flashcard 27: What is tangential velocity?

Answer: Velocity tangent to the circular path. Speed along the circular path's edge.

Flashcard 28: Calculate centripetal acceleration: $v=4$ m/s, $r=2$ m.

Answer: $8$ m/s². Using $a_c = v^2/r = 4^2/2 = 8$ m/s².

Flashcard 29: Find angular velocity: $\theta=\pi/2$ rad, $t=2$ s.

Answer: $\pi/4$ rad/s. Using $\omega = \theta/t = (\pi/2)/2 = \pi/4$ rad/s.

Flashcard 30: What is the effect of increasing radius on centripetal force?

Answer: Decreases centripetal force for constant velocity. Force inversely proportional to radius.
