FLASHCARD QUESTION

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

2.

FLASHCARD QUESTION

Front

How is centripetal acceleration calculated?

Back

Centripetal acceleration (a_c) is calculated using the formula: a_c = v^2 / r, where v is the tangential speed and r is the radius of the circular path.

FLASHCARD QUESTION

Front

What is the relationship between mass, velocity, and centripetal force?

Back

The centripetal force (F_c) can be calculated using the formula: F_c = m * a_c, where m is the mass of the object and a_c is the centripetal acceleration.

FLASHCARD QUESTION

Front

What is the formula for calculating the distance fallen by an object under gravity?

Back

The distance (d) fallen by an object under gravity can be calculated using the formula: d = 0.5 * g * t^2, where g is the acceleration due to gravity (approximately 9.81 m/s²) and t is the time in seconds.

FLASHCARD QUESTION

Front

What is the significance of the radius in circular motion?

Back

The radius of the circular path affects both the centripetal acceleration and the centripetal force required to maintain circular motion; a larger radius results in lower centripetal acceleration for the same speed.

6.

FLASHCARD QUESTION

Front

How does speed affect centripetal acceleration?

Back

Centripetal acceleration increases with the square of the speed; if the speed doubles, the centripetal acceleration increases by a factor of four.

7.

FLASHCARD QUESTION

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration always points towards the center of the circular path, perpendicular to the object's velocity.
