Proportional Reasoning - Univ G & Circular

Front

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

Back

The gravitational force will be one ninth.

Front

What is the effect on gravitational force if one mass is tripled and the distance is also tripled?

Back

The gravitational force will be one third.

Front

How does halving the tangential velocity affect the period of an object in circular motion with constant radius?

Back

The period is doubled.

Front

What is the effect on centripetal acceleration if the radius is doubled?

Back

Centripetal acceleration is halved.

Front

How does halving the tangential velocity affect centripetal acceleration?

Back

Centripetal acceleration is one fourth.

Front

Define gravitational force in the context of two masses and distance.

Back

Gravitational force is the attractive force between two masses, inversely proportional to the square of the distance between them.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

Front

Explain the relationship between tangential velocity and period in circular motion.

Back

The period is the time taken for one complete revolution; as tangential velocity decreases, the period increases.

Front

What is the formula for gravitational force?

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 increasing the radius of a circular path affect the speed of an object moving at constant tangential velocity?

Back

Increasing the radius allows the object to maintain the same tangential velocity while requiring less centripetal acceleration.
