The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract.
When the chains cool down, they relax and stretch out, causing the material to expand. When a basketball bounces against the ground and gets deformed and then recovers its shape, the air inside that ball is temporarily compressed and will again have its original volume when the ball recovers during the rebound.
The main reason is the way air leaks out of the balls over time. When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop. Squash balls heat up over the course of a game. Either the air in them gets pressurized, or the rubber just gets more flexible, but a squash ball will get more bouncy larger f as it heats up.
Blue dots are better for rallies and it will ensure the ball remains warmer to help it bounce better. A dependent variable is a variable whose value depends upon independent variable s. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The two main variables in an experiment are the independent and dependent variable.
If a bouncy ball is dropped onto a hard surface, it flattens somewhat as it contacts this surface, and the kinetic energy of its motion is converted into potential energy.
This is very similar to the potential energy stored in a spring that gets compressed; once it is released, it pushes out with energy equal to what was required to push it in but in the opposite direction. The potential energy of the bouncy ball converts back into kinetic energy, which is applied in an equal and opposite direction to the force that originally caused the collision. Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions configurations of the objects within a physical system.
This form of energy has the potential to change the state of other objects around it, for example, the configuration or motion. Begin typing your search term above and press enter to search. Press ESC to cancel. Skip to content Home Cover Letter What makes balls bounce higher?
Cover Letter. Ben Davis April 16, What makes balls bounce higher? Why do golf balls bounce so high on concrete? What factors affect the bounce height of a ball? The elastic properties reduce the amount of deformity that comes from an impact, making it more effective at bouncing. Materials with elasticity allow the bouncy ball to store energy when it hits the floor or other surface.
That energy is then released, pushing the ball into the air over and over again. Temperature also impacts the bounciness of a bouncy ball.
