How Fast Is the child going at the bottom of the slide if the slide is frictionless?
without friction, the speed of the child reaching the bottom is 5.48m/s . if 23J of energy is dissipated due to friction, then there are 23J less of KE .
How does the total energy of the child at the bottom of the slide compare to their total energy at the top of the slide?
When the child reaches the bottom, the child has both kinetic energy and thermal energy as some energy was converted to heat because of the friction on the slide. This difference between the at the top and the at the bottom is the energy lost to friction.
What is the speed at the bottom of the slide?
That means the velocity at the bottom of the slide is 10 m/s. The average velocity is half that, 5 m/s.
What would happen to a child going down a slide if there was too much friction?
Friction is a force that occurs whenever two objects rub against each other, such as a slide and a person’s backside. Without friction, a slide would accelerate the rider too quickly, resulting in possible injury. Certain materials called lubricants can reduce the effects of friction.
What type of energy is a child sliding down a slide?
Kinetic and Potential Energy As she begins to slide, the potential energy is converted to kinetic energy. Any object that is in motion contains kinetic energy. The amount of kinetic energy depends on mass and speed.
What form of energy does the child have at the top of the slide?
The child has converted their potential energy at the top of the slide in kinetic energy.
Why is the speed the same at the bottom of the slide?
Ignoring friction, final speed at the bottom will be same for both because they loose same potential energy (assuming same mass). Therefore, acceleration down the flatter path will be less, and it will take longer time to attain final speed. In other words, steeper the path, faster is the downward acceleration.
Why do you slide faster in water slide compared to regular slides?
Friction force is the initial force here (neglecting external forces like pushing yourself etc), water is passing between your body and slide, there will be a limit for the force your body is applying to slide, and till you reach this limit friction force will contribute to your fall. More surface > faster slide.
What motion is sliding down a slide?
frictional motion
Sliding is a type of frictional motion between two surfaces in contact. This can be contrasted to rolling motion.
When you slide down a slide on the playground what are two forces that are present How do they each affect your movement?
The force of friction results from two things rubbing against each other- like a pinecone and the slide. Friction works against gravity to slow items as they go down the slide. Each item going down the slide creates a different amount of friction (depending on many variables) to affect its speed.
What is sliding friction example?
Examples of Sliding Friction Rubbing both the hands together to create heat. A child sliding down through a slide in a park. A coaster sliding against a table. A washing machine pushed along with the floor.
How does a child sliding on a slide get kinetic energy?
Kinetic and Potential Energy When a person first sits at the top of a slide, she contains potential energy. Potential energy is any stored energy, and exists in any object or being capable of falling or moving. As she begins to slide, the potential energy is converted to kinetic energy.
