All Flashcards
What is the effect of a net force acting towards the center of a circular path?
It causes centripetal acceleration, resulting in uniform circular motion.
What happens when the radius of a circular path increases, assuming constant speed?
The centripetal acceleration decreases.
What happens to the center of mass when external forces act on a system?
The center of mass accelerates as if all the mass is concentrated there and all external forces act on that point.
What happens when the velocity of an object in UCM increases?
The centripetal acceleration increases.
What is position?
Where an object is located.
What is displacement?
The change in position; a vector quantity.
What is velocity?
The rate of change of position; a vector quantity.
What is acceleration?
The rate of change of velocity; a vector quantity.
What is centripetal acceleration?
Acceleration directed towards the center of a circular path.
What is centripetal force?
The net force causing centripetal acceleration, directed towards the center of the circle.
What is the center of mass (COM)?
The average position of all the mass in a system.
What is the effect of a net force acting towards the center of a circular path?
It causes centripetal acceleration, resulting in uniform circular motion.
What is the effect of doubling the radius on centripetal acceleration, given constant speed?
The centripetal acceleration is halved (a_c = v^2/r).
What happens to the center of mass if one mass in a two-mass system is increased?
The center of mass shifts closer to the heavier mass.
What happens when an external force acts on a system of particles?
The center of mass of the system accelerates.
