The discussion centers on the dynamics of a ball moving in a horizontal circle while attached to a string. It is established that the force acting on the ball changes its direction but not its speed, as the speed remains constant throughout the motion. Participants confirm their understanding of scalar speed, which lacks direction, and vector velocity, which includes direction, reinforcing the distinction between these two concepts.
PREREQUISITESStudents studying physics, educators teaching circular motion concepts, and anyone interested in understanding the dynamics of forces in motion.
Correct. Are you familiar with the definitions of scalar speed and vector velocity?talknerdy2me said:Homework Statement
While a string is attached to a ball and the ball moves in a horizontal circle at a constant speed, does the force change both the direction and speed of the ball? Explain.
Homework Equations
No equations necessary.
The Attempt at a Solution
*I think* the force changes the direction but not the speed since the speed is constant?
Yes I am scaler = no direction and vector = with direction.berkeman said:Correct. Are you familiar with the definitions of scalar speed and vector velocity?
