Proportional Reasoning - Univ G & Circular

Front

What is centripetal acceleration?

Back

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

Front

How does doubling the mass of an object affect centripetal acceleration if the force applied is increased six times?

Back

Centripetal acceleration is 3 times greater.

Front

What happens to the period of an object in circular motion if the radius is tripled while keeping tangential velocity constant?

Back

The period is 3 times longer.

Front

How does tripling the distance between two objects affect the gravitational force between them?

Back

The gravitational force will be one ninth.

Front

What is the relationship between radius and centripetal acceleration?

Back

If the radius is tripled, centripetal acceleration is one third.

Front

If one mass in a gravitational interaction is tripled, how does that affect the gravitational force?

Back

The gravitational force will be 3 times stronger.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v^2 / r, where v is the tangential velocity and r is the radius.

Front

What is the effect of increasing the radius on the speed of an object in uniform circular motion?

Back

If the tangential velocity remains constant, increasing the radius does not affect the speed.

Front

Define gravitational force in the context of two masses.

Back

Gravitational force is the attractive force between two masses, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Front

What happens to centripetal force if the mass is doubled and the acceleration is increased?

Back

Centripetal force is directly proportional to mass and acceleration.
