This will create an acceleration up the slope making the ski decelerate as it travels down the slope. Making a Ski Decelerate as it Slides Down a Slopeįor this to happen the vertical component of the reaction force needs to be greater than the gravitational force, and there to be a sideways force acting up the slope. To make the ski continue down the slope as a constant speed, the vertical component of the reaction forces due to both gravity and momentum combined cancel out the gravitational force, with the acceleration due to gravity and deceleration due to momentum also canceling each other out. As the reaction force is not vertical the vertical component of the reaction force due to gravity is not strong enough to counteract the gravitational force, but as the ski is opposing momentum as well there is a reaction force due to momentum that needs to be added. This component acts as resistance against the skis velocity and makes the skis momentum produce a force. The other ways is to have the ski leant up the slope slightly so that the reaction force from the snow has a component that acts sideways up the slope. This leaves no left over forces and will keep the ski traveling at a constant velocity. The first way is very simple, the ski is flat to the gravitational force, with the reaction force is in the opposite direction to gravity, and the snow supporting the ski so that the reaction force is the same magnitude as the gravitational force. Again there are 2 main ways in which this can happen. Making a Ski Slide Down a Slope at a Constant Velocityįor this to happen the reaction force must cancel out the gravitational force and leave no forces left over to cause an acceleration in any direction. The snow then gets pushed down the slope by the ski, letting the ski accelerate down the slope.

The other way is for the ski to be flat to the gravitational force, with the reaction force created acting in the opposite direction to gravity, but with the snow not being strong enough to support the full gravitational force. This means that the vertical component of the reaction force must be smaller than the gravitational force, and that there is a sideways component that will also push the ski down the slope, resulting with the ski accelerating down the slope. The ski can be tilted at an angle down the slope, so that the reaction force is not acting in the opposite direction. There are 2 main ways in which this happens. In order for a ski to accelerate sideways as it travels down a slope, the gravitational force must be greater than the vertical component of the reaction force from the snow. Making a Ski Accelerate as it Travels Down a Slope To show how these work to we are going to use the situation where the ski is sideways to a slope, and only consider the sideways forces and movement. Put simply the effects are make a ski accelerate down a slope, keep a ski at a constant velocity as it travels down a slope, make a ski decelerate as it travels down a slope, and stop a ski so that it doesn't travel any further sideways down a slope. See where other lines get stacked with angle chart and that you can see your angle degrees.There are 4 different effects an edge can produce as you are skiing, the effects depend on the forces going through the edge, the angle the edge is at, and the snow conditions.

One line of the angle must be on 0 angles of the chart. Stack it then you need to move and align the center of the protractor with the center point of the angle. How can I measure an angle with a protractor?įirst, you need to align your protractor with the angle that you wanna measure. You can also measure an angle with a 360-degree chart protractor. Also, a reflex angle that had an angle between 180 and 360 degrees. The fourth angle called a straight angle that had 180 degrees angle. Third, an obtuse angle that had an angle between 90 and 180 degrees. Second, the right angle, it had 90 degrees angle. First, an acute angle that had an angle between 0 and 90 degrees. An angle in geometry is when two lines meet and share the same point. It is easier with a full circle protractor than using a half-circle protractor. You can use a half-circle protractor that has a 180-degree chart or full circle protractor that has a 360-degree chart. It will really help you to draw an angle.

There are so many ways to draw a circle like: A circle is a figure that has a round shape with no corners and edges.
