Why does friction cause a skater to slow down and eventually stop?
The force of friction opposes the motion of the rolling skateboard and would eventually bring it to a stop without any help from Lauren. Friction opposes the motion of all moving objects, so—like the skateboard—all moving objects eventually stop moving even if no other forces oppose their motion.
Will the skater in the simulation ever come to a stop?
No the skater will never stop Yes eventually the skater will no longer have any kinetic energy Yes eventually the skater will no longer have any potential energy 10 poir QUESTION 31 How does his max speed compare to the max speed in the previous problem?
What is the force that acts upon a rollercoaster after it reaches the top of the hill?
Potential energy is converted to kinetic energy as the roller coaster goes down the hill.
What happens when you increase the skater’s mass?
When the skater’s mass increased, he had higher kinetic and potential energy as he went up and down the ramp. As potential energy decreases, kinetic energy increases, and vice versa. This occurs because kinetic energy is the energy of motion and potential energy is stored energy.
Which statement about an apple falling from a tree is true?
Answer: The correct option is ‘When an apple falls from a tree, the only force present is the gravitational force of the earth on the apple. ‘
What is happening to the kinetic energy with time how is it related to the speed and height of the skater?
The total energy of the skateboarder remains constant. Question: How does the speed relate to the potential and kinetic energy of the skater? As the skater’s speed increases, the kinetic energy increases. As the speed decreases, the kinetic energy increases.
Where is the mechanical energy going as the skater slows down?
As he speeds up going down the pipe, his potential energy drops while his kinetic energy increases. As he slows down heading back up the pipe, his kinetic energy drops as his potential energy increases. This is a back and forth process that happens as the skater moves up and down the pipe.
When an ice skater who is doing a spin pulls her arms in?
If a figure skater starts spinning slowly with her arms and possibly one leg extended, she initially has a high moment of inertia and a low angular velocity. If she pulls her arms and leg in closer to her rotational axis, her moment of inertia decreases.
How does a figure skater slow down the rotation?
Moment of inertia determines how easy it is for an object to speed up or slow down, and describes the resistance that a force is working against. A larger moment of inertia—like when a skater extends their arms—will result in a slower rotational speed.
