The higher the skater is the more potential energy he has. As his height decreases, his potential energy decreases and his kinetic energy increases.
How does the height of the skateboarder affect the amount of potential energy they have?
Potential energy is different depending on what force the skateboarder is feeling, but in this case that force is gravity. With gravity, the potential energy is proportional to how high from ground level the skateboarder is: the higher the skateboarder, the more potential energy she has.
How does potential energy affect a skater?
As the skateboarder moves, her potential energy is converted to kinetic energy (KE), or the energy of motion as her position changes along the track and the velocity changes. The maximum amount of kinetic energy the skateboarder can have is entirely dependent on the amount of potential energy of the system.
In what way is height related to potential energy?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
Does the skater hit the same height on the opposite sides of the track?
Yes, the skater hits the same height on both sides of the track.
What happens to the gravitational potential energy as you go along the track?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
Where does the skater have the most potential energy?
As previously discussed, the skater has the most potential energy at the top of the slope. As the skater moves down the slope, his potential energy decreases as the kinetic energy increases.
Why the skater rises to the same height on each side of the ramp?
The skater is going up and down the ramp without losing energy, because the ramp is frictionless. Due to this, he continues to reach the same height on each end of the ramp as his kinetic energy (energy of motion) is converted to gravitational potential energy (energy of position).
What happens to the potential energy as the skater goes from the top of the skate ramp to the bottom?
As the skateboarder goes down the ramp, potential energy is converted to kinetic energy. Because of friction, some of the energy in the system is converted to heat energy.
What happens to the potential energy as the skater goes up what happens to the kinetic energy as the skater goes up what happens to the total energy as the skater goes up?
The skater’s potential energy increases as he moves up the ramp, since the kinetic energy is being converted to potential energy. 9. How does the skater’s total energy change as he moves down the ramp? The total energy stays the same as he moves down the ramp, since energy is converting and not going anywhere.
What happens to potential energy when height is doubled?
Hence, when height is doubled, potential energy is also doubled.
How Does height affect potential and kinetic energy?
For instance, the kinetic energy of the object will be higher if the object is placed at a greater height. Potential energy isn’t transferrable and it depends on the height or distance and mass of the object.
Why is potential energy greater at higher height than on the ground?
Because potential energy is the maximum available energy that required to convert into other forms. At a higher altitude, you require more energy to make the object move. So as the height increases, the potential energy is also increase.
What variables seem to affect how the skater moves?
Friction. As we turn “friction” on, the difference about the skater’s motion with friction compared to without it is that there is more thermal energy. The more friction there is, the slower the skater will move. The less friction there is, the faster the skater will move.
What factors affect potential energy?
This energy is stored energy and means that it can be used at a later time to cause an object to move. Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.
What is the relationship between potential energy kinetic energy and speed?
Potential energy is position relative. In other words, it changes depending on an object’s height or distance and the mass of the object. Kinetic energy changes depending on an object’s speed and its mass. If we think about a waterfall, some still water at the top of the waterfall has potential energy.
What is the relationship of mass weight and height to the PE of an object?
For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
How can mass weight and height affect the PE of an object?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
How do you compare the potential energy of the moving object at the highest point compared to its kinetic energy?
At an object’s maximum height, kinetic energy is zero/maximum while the potential energy is zero maximum. 3. At an object’s lowest point, kinetic energy is zero/maximum while potential energy is zerg/maximum. 4.
At what point does the skater have the greatest kinetic energy?
Thus, the skater’s kinetic energy is greatest at the lowest point of the track, where the skater is moving the fastest.
What was the effect on the skaters maximum potential energy when he was placed further down the ramp?
The skater’s kinetic energy increases as he moves down the ramp. The skater’s kinetic energy decreases as he moves up the ramp. As the skater moves down the ramp, his potential energy decreases.
