SUMMARY

The discussion focuses on identifying the forces acting on a skier sliding down a 15-degree slope with friction. The relevant forces include Kinetic Friction, Weight, and Normal Force. Static Friction is not applicable as it pertains to initiating movement, while Tension and Thrust are deemed irrelevant in this context. The consensus is that Kinetic Friction, Weight, and Normal Force are the primary forces acting on the skier.

PREREQUISITES
  • Understanding of basic physics concepts related to forces
  • Familiarity with Newton's laws of motion
  • Knowledge of friction types: Kinetic and Static Friction
  • Basic trigonometry for analyzing slopes and angles
NEXT STEPS
  • Study the effects of friction on inclined planes in physics
  • Learn about the decomposition of forces on inclined surfaces
  • Explore the role of Normal Force in various scenarios
  • Investigate the concept of Thrust in physics and its applications
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the dynamics of forces acting on objects in motion on inclined surfaces.

Quick question about forces!

Homework Statement



A skier is sliding down a 15 degree slope. Friction is not negligible. Identify all forces on the skier.

Homework Equations



n/a

The Attempt at a Solution



The choices are: Tension, Kinetic Friction, Weight, Static Friction, Thrust, and Normal Force.

I drew a picture and assumed Kin. Friction, Weight, Thrust, and normal force were the answers but I got it wrong.

I don't think static friction is the answer because that is used to determine the force that must be overcome to initiate movement. Tension seems like a cable or string thing and not something that would affect a skier. I guess I don't know what thrust is but would it be correct to say that K. Friction, weight, and N. Force are the only forces on the skier or am I missing something? Thank you for your help!

Looks right.

There might be thrust if they were pushing with their arms with their poles, but that sounds beyond the scope of the question.
