How does skidding sideways to stop remove energy from a skier?

Skidding sideways to stop increases friction between the skis and the snow, which converts the skier's kinetic energy into heat through friction. This loss of energy slows down the skier's forward motion and brings them to a stop.


Explain how a skier gliding down a hill illustrates the conservation of energy.?

because the skis are on the snow it causes friction which turns in to heat causing the skier to stop


How can a skier achieve greater velocity than a skydiver?

If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.


Does skiing have static friction?

Yes, skiing involves static friction, particularly when the skis are at rest or moving slowly on the snow. Static friction occurs between the ski base and the snow, helping to grip the surface and prevent slipping. As the skier gains speed, kinetic friction takes over, allowing for smoother gliding. Proper ski maintenance, including waxing, can reduce friction for better performance.


When is friction not useful in skiing?

Friction is not useful in skiing when a skier wants to maintain high speeds or glide smoothly over snow. In these situations, reducing friction through techniques like waxing the skis or using a smoother ski base is beneficial. Additionally, when performing tricks or jumps, minimizing friction can help the skier achieve more fluid movements.


What role does friction have in the energy transformations of a person skiing downhill?

Friction plays a crucial role in the energy transformations of a person skiing downhill by converting some of the skier's kinetic energy into thermal energy. As the skis glide over the snow, friction between the skis and the snow surface generates heat, which can slow the skier down. While this energy loss can reduce speed, it also helps control the skier's descent, allowing for maneuverability and stability. Overall, friction is essential for balancing speed and control while skiing.


What are the forces of a skier?

The forces acting on a skier include gravity, which pulls them downward, and normal force, which is the upward force exerted by the snow. Additionally, friction between the skis and the snow resists motion, while aerodynamic drag opposes forward movement as the skier descends. These forces interact dynamically as the skier navigates slopes and turns.


Explain the role of friction has in the energy transformation of a person skiing downhill?

Friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. ur welcome. you have to give me 5 bucks.


A skier slides horizontally along the snow for a distance of 21 meters before coming to rest The coefficient of kinetic friction is 0.050 how fast was the skier going?

For the skier to come to rest, it has to lose all its kinetic energy. Ignoring the drag force caused by air, kinetic energy is strictly lost through friction with the snow. The kinetic friction force Fk is mu, the kinetic friction coefficient, times the normal to the surface, in that case the total weight M*g of the skier. The total work the friction does against the skier is thus Fk times x, where x is the distance over which the friction force acted. Remembering the formula for kinetic energy, the principle of energy conservation thus dictates the following equality : 1/2*M*v^2 = mu*M*g*x We see the total mass of the skier becomes irrelevent since it cancels out of the right and left hand side of the equality. Therefore, the speed at which the skier was going before starting to slow down is v = sqrt(2*mu*g*x) and since mu = 0.050 g = 9.81 m/s^2 x = 21 m then v = 4.539 m/s, which is equivalent to 16.332 km/h once you multiply by 3.6 km/h per m/s.

What force is used when skiing?

When skiing, the primary forces that are utilized include gravity, friction, and centripetal force. Gravity pulls the skier down the slope, while friction between the skis and the snow aids in controlling speed and direction. Centripetal force comes into play when turning, allowing the skier to navigate around curves.


What two forces slows down skiers when going down a hill?

The two forces that slow down skiers when going down a hill are friction and air resistance. Friction occurs between the skis and the snow, as well as between the skis and the boots, causing a resistance that reduces the speed. Air resistance is the force exerted by the air on the skier as they move downhill, acting in the opposite direction to the skier's motion and further slowing them down.
