To calculate the speed of a skier going down a slope, you can use the conservation of energy principle. The potential energy at the top of the slope (mgh, where m is mass, g is gravitational acceleration, and h is height) converts to kinetic energy (0.5 mv²) at the bottom. By setting these two energies equal, you can solve for the speed (v) using the formula v = √(2gh). Additionally, factors like friction and air resistance can affect the actual speed, so they may need to be considered for a more accurate calculation.

How do you calculate speed from slope?
To calculate speed from a slope on a graph, you first determine the rise over run, which is the change in vertical distance (rise) divided by the change in horizontal distance (run). If the graph represents distance over time, the slope indicates speed, calculated as speed = distance/time. A steeper slope indicates a higher speed, while a flatter slope indicates a lower speed.
What does the slope of speed-time graph calculate?
The slope of a speed-time graph represents acceleration. It indicates how quickly an object’s speed is changing over time. A positive slope shows an increase in speed (acceleration), while a negative slope indicates a decrease in speed (deceleration). A slope of zero means the object is moving at a constant speed.
Can you calculate speed from a motion graph?
If you graph distance vs. time, the slope of the line will be the average speed.
Does changing the height of a ramp affect the speed of the car going down the ramp?
Changing the slope of the ramp will affect the speed of the vehicle going down it.
What is the speed of a slope?
A slope does not have any speed.
Why is a skier going down hill a slope?
A skier going downhill on a slope is due to gravity pulling the skier downwards. The angle of the slope causes the skier to accelerate as they descend. By controlling their speed and direction using their skills and equipment, the skier can navigate the slope safely.

How do you calculate speed of a distance time graph?
Speed (in the radial direction) = slope of the graph.
What does the slope of speed-time graph calculate?

A positive slope shows an increase in speed (acceleration), while a negative slope indicates a decrease in speed (deceleration). A slope of zero means the object is moving at a constant speed.

How do you determine the speed of an object by looking at a graph?
To determine the speed of an object from a graph, you can calculate the average speed by finding the slope of the line connecting two points on the graph. The steeper the slope, the higher the speed. Alternatively, you can also find the instantaneous speed by looking at the slope of the tangent line at a specific point on the graph.
What does a skier has a top of a hill and coming down a hill?
A skier at the top of a hill has potential energy due to their height above the ground. As they come down the hill, this potential energy is transformed into kinetic energy, allowing them to slide down the slope thanks to gravity. The skier's speed will increase as they descend due to the conversion of potential energy into kinetic energy.
Does changing the height of a ramp affect the speed of the car going down the ramp?
Changing the slope of the ramp will affect the speed of the vehicle going down it.
What is the speed of a slope?
A slope does not have any speed.
Why area below the distance-time graph is used to calculate speed?
That's not correct. If you have a graph of distance as a function of time, the speed is the slope of the graph.
A car distance time graph is a straight line with a steep slope. How would you describe the car's speed?
If the slope is 'uphill' then the car is going faster
Which is travelling faster a cyclist who travels 400m in 20s or a skier who travels 1500m in 1 min workings?
The cyclist is traveling faster as they cover 400m in 20 seconds, which means they are going at a speed of 20m/s. The skier covers 1500m in 1 minute, which is equivalent to 25m/s. Therefore, the skier is traveling faster.
