Front

What is the direction of the centripetal force acting on an object in circular motion?

Back

Towards the center of the circle.

Front

What is centripetal acceleration?

Back

The acceleration directed towards the center of a circular path, responsible for changing the direction of an object in circular motion.

Front

What is the formula for calculating the speed of an object in circular motion?

Back

v = 2πr/T, where v is speed, r is radius, and T is the period.

Front

What is the relationship between period and frequency in circular motion?

Back

Frequency (f) is the reciprocal of the period (T): f = 1/T.

Front

What is the formula for centripetal force?

Back

F_c = mv^2/r, where F_c is centripetal force, m is mass, v is speed, and r is radius.

Front

What is gravitational force?

Back

The attractive force between two masses, calculated using F = G(m1*m2)/r^2.

Front

What does the gravitational constant (G) represent?

Back

G is the proportionality constant in Newton's law of universal gravitation, approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases with the square of the distance between the centers of two masses.

Front

What is the formula for calculating the gravitational force between two objects?

Back

F = G(m1*m2)/r^2.
