SUMMARY

The discussion centers on the distinction between two types of forces involved in tennis: linear force and torque. Linear force is responsible for changing the ball's velocity and momentum, while torque affects angular velocity and angular momentum. The tennis coach seeks terminology to describe these forces more accurately, suggesting the use of "increase the torque" when referring to adding spin to the ball. The conversation references Newton's laws of motion and the concept of torque as foundational principles in understanding these forces.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of linear momentum and velocity
  • Familiarity with angular momentum and angular velocity
  • Concept of torque in physics
NEXT STEPS
  • Research the application of Newton's laws of motion in sports
  • Explore the relationship between torque and angular momentum
  • Study the effects of linear force on ball trajectory in tennis
  • Learn about advanced techniques for generating spin in tennis
USEFUL FOR

Tennis coaches, sports scientists, and players looking to enhance their understanding of the physics behind ball movement and improve their game strategy.

Hi, I am a tennis coach and not very sciency, so if there's a simple answer to this question rather than a crazy physics answer it would be much appreciated.

I hit the ball, some of the energy from my racket "pushes" thru the ball creating momentum, another part of the energy from my racket "brushes" around the ball creating spin.

Are there 2 different names for these kinds of force and what are they?

So for instace rather than saying " put more spin on the ball. " i could say "increase the ... " or something like that


Thanks for the help.
