All Flashcards
What is position?
Where an object is located; its 'address'.
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 the circular path in uniform circular motion.
What is centripetal force?
The net force that causes centripetal acceleration; it's directed towards the center of the circle.
What is the center of mass (COM)?
The average position of all the mass in a system; the point where the system would balance.

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 difference between uniform and non-uniform motion?
Uniform motion: constant velocity, zero acceleration. Non-uniform motion: changing velocity, non-zero acceleration.
What is the difference between speed and velocity?
Speed is the rate of motion. Velocity is the rate and direction of motion.
