Question

Can you tell me how any of these terms relate to the Olympic sport luge? inertia, free fall, terminal velocity, projectile motion, momentum, motion, force, static friction, kinetic friction

PLEASE HELP IF YOU CAN!!

Answer 1

I can attempt to help with a few of them.
inertia - the tendency of an object to remain in its state of motion until acted upon by some external force. Well, the luge is just gonna sit there unless the guy gets it moving to the slope where gravity can start it going down the run. As it is going down the run, it wants to keep moving until something stops it or turns it. Momentum is also close to this. Momentum is a product of an object's mass and inertia. If I were to throw a baseball at you and tell you to change it's direction with a bat, you would have no trouble. If I were to drive at you in my car and tell you to change the car's velocity with the same bat, you couldn't. The car having moremass, has more momentum. However, if I were to lob a ball at you and tell you to change the momentum with your bare hand, you could. Now, if Nolan Ryan threw that same baseball at you at over 120mph and you had to use just your bare hand to change the ball's velocity, you probaly could, but it'd sure hurt. The increase in speed increased the ball's momentum.
terminal velocity - absolutely maximum velocity an object can achieve relative to the environment it's moving through and forces that environment exerts upon the object factoring in object's mass
motion - movement
When it crests a hill in the track and comes back down the other side, if the luge's velocity is adequate, the rider may experience a feeling of free fall. The space shuttle does this when in orbit. It is falling to the ground all the time. But, it also has a "forward" instead of just "downward" velocity letting it arc out over the curavature of the earth and fall into nothing. Velocity is a combination of an object's speed AND direction.
There really is not enough room in this forum to fully explain all these aspects of your question. Try looking through your physics book at the definition of those terms to see what each could be talking about during a luge run.
