FLASHCARD QUESTION

Front

What is the formula for centripetal force?

Back

F_c = (m * v^2) / r, where F_c is centripetal force, m is mass, v is tangential velocity, and r is radius.

FLASHCARD QUESTION

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, calculated as a_c = v^2 / r.

FLASHCARD QUESTION

Front

What is the relationship between tangential speed and radius in circular motion?

Back

Tangential speed (v) is directly proportional to the radius (r) and the angular velocity (ω): v = r * ω.

FLASHCARD QUESTION

Front

Calculate the centripetal force required to make a 5 kg ball move 4 m/s in a circle with a radius of 2 m.

Back

40 N
