What causes the skier to move forward?

The force from the snow pushes on the ski causing the skier to change direction. The skier responds with muscular tension to resist and balance against that force.

What type of energy is sledding down a hill?

At the bottom of the hill, you have the most kinetic energy because you are moving the fastest and all the potential energy has turned into kinetic. Sledding only works when there is snow on the ground, if you try to go sledding on a grassy hill it won’t be as fun because snow helps to eliminate friction.

What forces limit the speed of a skier going down a slope?

The more friction, the more heat you generate instead of speed, and the slower you go down the slope. Skiers wax the bottom of their skis to reduce friction as they go down the slope.

What is the net force of the skier?

zero
As the skier is being pulled up and out of the water, her velocity is increasing. Thus, she is accelerating, and the net force acting on her is not zero. The skier is not in equilibrium….

(a)	The skier is floating motionless in the water.
(d)	The skier has let go of the tow rope and is slowing down.

What is the normal force on the skier?

While gravity is acting straight down on the skier, a normal force is exerted on the skier that opposes gravity. As the skier skis down the hill, he or she will encounter an acceleration. This acceleration is due to gravity caused by a change in the skiers velocity.

What is the mechanical energy of the skier?

potential energy
If starting from rest, the mechanical energy of the skier is entirely in the form of potential energy. As the skier begins the descent down the hill, potential energy is lost and kinetic energy (i.e., energy of motion) is gained.

What type of energy is standing on top of a mountain?

Potential Energy is defined as the energy stored by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. When you (or a rock) are standing at the top of a hill, you possess more potential energy than when standing at the bottom.

What happens to that energy after the skier races down the slope of the mountain?

What happens to the potential energy after the skier races down the slope of the mountain? it is converted to kinetic energy.

What energy transformations occur as a skier glides down a gentle slope at constant speed?

When a skier glides down on a gentle slope with constant speed, the acceleration remains zero. Hence, the velocity remains constant ensuring the kinetic energy to be constant throughout the process.
