At what position is the kinetic energy of the skater the highest?
At the top of the ramp, before he starts moving downward, the skateboarder has zero KE, due entirely to the fact that he is not moving. At the bottom of the ramp, the skateboarder has maximum KE because he is moving at the fastest speed.
What direction is the skater moving when their potential energy increases?
In which direction is the skater moving? Justification: Due to the force of gravity, an object moving downhill speeds up, while an object moving uphill will slow down. Since the kinetic energy is increasing, the speed must be increasing as well, and the skater must moving down the slope, or to the right of the diagram.
What happens to the speed and kinetic energy of the skater when it is moving downward the track?
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. Once the kinetic energy is converted to heat, the energy cannot be converted back to the potential or kinetic energy in the system.
How does increasing skater’s mass change the skaters?
Changing the mass of the skater will change the potential and kinetic energy whichwill lead to a change in the total energy.
What energy is gradually increasing and eventually causes the skater to slowly come to a stop?
The skater will not roll back and forth forever. He will eventually come to a stop. There will be thermal energy which keeps increasing.
What is the relationship between the PE and the height of the skater on the track?
What is the relationship between the PE and the height of the skater on the track? PE increases as the skater gets higher on the track. 3. Watch what happens to the KE as the skater moves faster and slower on the track.
What is different about the skater’s motion with friction compared to without it?
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 happens to the speed when you increase friction?
Friction increased as the normal force on the object increased. That force is proportional to the velocity with which it is moving. This yes, the drag force or viscous force will increase as the velocity increases and this is generally associated with the object moving in fluids like water or air(freely falling).
