Circular and Gravitation FUNDAMENTAL APPLICATIONS

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

How does mass affect gravitational force?

Back

Gravitational force is directly proportional to the product of the two masses involved.

Front

What happens to gravitational force if the distance between two objects is doubled?

Back

The gravitational force becomes one-fourth as strong, since it is inversely proportional to the square of the distance.

Front

Define centripetal acceleration.

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, keeping an object moving in that path.

Front

What is the relationship between centripetal force and mass?

Back

Centripetal force is directly proportional to the mass of the object moving in a circular path.

Front

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

Back

The net force is directed towards the center of the circular path.

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where a_c is centripetal acceleration, v is the linear speed, and r is the radius of the circular path.

Front

What is the significance of the term 'tangent' in circular motion?

Back

The speed of a circular moving object is always directed tangent to the object's path.

Front

How does the radius of a circular path affect centripetal acceleration?

Back

Centripetal acceleration is inversely proportional to the radius; as the radius increases, the centripetal acceleration decreases for a constant speed.

Front

What is gravitational field strength (g)?

Back

Gravitational field strength is the force per unit mass experienced by a small test mass placed in a gravitational field.
