What does thats the way the ball bounces mean? – Also, that’s the way the ball bounces or the cookie crumbles. That is the way matters have worked out and nothing can be done about it. For example, I’m sorry you got fired but that’s how the ball bounces, or They wanted a baby girl but got a third boy—that’s the way the cookie crumbles.
Is Sid the Science Kid motion capture? – The show is produced by motion capture which allows puppeteers to voice digitally animated characters in real time. Production began in January 2003 with 42 half-hour episodes of Sid the Science Kid having been ordered.
What is the hypothesis of a bouncy ball? – The hypothesis states that if the height from which a bouncy ball is dropped is raised in increments of 20cm, respectively, from 20cm-200cm, then the bouncy ball dropped from 200cm will exhibit a greater rebound percentage.
What’s that smell Sid the Science Kid? –
What forces act on a bouncing ball? – The forces acting on a spinning ball during impact are the force of gravity, the normal force, and the force of friction (which has in general both a ‘translational’ and a ‘rotational’ component).
What is the dependent variable in the bouncing ball experiment? – 2. Because we can drop the ball from any height we choose, the drop height is called the independent variable. But since the rebound height depends on the drop height, the rebound height is called the dependent variable.
What affects the bounce of a ball? – The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
Why do balls bounce higher when dropped from a greater height? – If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
Why does a ball bounce lower each time? – At impact, most of the kinetic energy is transferred to elastic energy in the ball (by its deformation) and not to the floor. Some energy is also converted to other forms like heat and sound. These other forms of energy, are mostly losses and they are not recovered thus making the ball bounce back to a lower height.
Why do smaller balls bounce higher? – The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.
Why do balls bounce higher on hard surfaces? – As the ball is released, gravity pulls the ball downwards and transforms that potential energy into kinetic energy, the energy of motion. The harder the court surface is the more energy a dropped ball retains and the higher it rebounds.
