Back
The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

FLASHCARD QUESTION
Front
What is the relationship between velocity and acceleration in circular motion?
Back
In circular motion, even if the speed is constant, the direction of the velocity vector changes, resulting in centripetal acceleration.

FLASHCARD QUESTION
Front
What does it mean for an object to be in uniform circular motion?
Back
An object is in uniform circular motion when it moves in a circular path at a constant speed, meaning its velocity is constant in magnitude but changing in direction.

FLASHCARD QUESTION
Front
How does the radius of a circle affect centripetal acceleration?
Back
Centripetal acceleration is inversely proportional to the radius; as the radius increases, the centripetal acceleration decreases for a constant speed.
