The Maximum Height of the bounce of a ping pong ball Introduction This experiment‚is an investigation into the maximum height of the bounce of a ping pong ball when it is first released.This is because of the unpredictability of the bounce not always reaching the same height.This we can assume their are many factors effecting the bounce of the ping pong ball.The following experiment will determine how different surfaces on which a ping pong ball is released affects the height of the first bounce

The area we assessed during this Saturday afternoon was downtown Jamestown. As it could be expected there were not a lot of people out being a weekend. There are museums and theaters in honor of Lucille Ball which act as a tourist attraction. The Lucille Ball Little Theater was started in 1936 and it was where the famous actor started her career. A quick search on the internet indicates that most of the buildings were built before a long time ago and most of them are apartments with a few others

This literature review for Chemistry is to help answer the question how does the amount of air pressure in a soccer ball affect how high it bounces when dropped. I think the ball will bounce higher when it has greater air pressure. We will explore atmospheric pressure‚ “which is the pressure exerted by the weight of the atmosphere”. www.kids.earth.nasa.gov And air pressure‚ “which is the force exerted on you by the weight of air molecules”. Other items in play will be gravitational force and

cement is the most hardest surface Background Information: When the ball comes in contact with the surface it will rebound the same amount of force hit on the ground back to the ball. Due to the gravitational pull the tennis ball will make it lose force and it will become weaker for every bounce. Resources/Equipment: A surface‚ 30 cm ruler and a tennis ball Risk Assessment: Losing the ball: Do it in a enclosed area‚ The ball bouncing on an object and the surface having a uneven ground: Look for

are literally thousands of Ball Mills in use throughout the world‚ many of them in the cement industry. Few installations have a comprehensible method of controlling and recording exactly what ball size distribution is in‚ or should be in‚ the Ball Mill. As mills are supplied for ever increasing capacities‚ the ball size distribution and wear exact a tremendous effect on the profitability of producing finish cement. Improper size distribution or filling level of the ball charge can easily reduce the

The Energy-Saving ball mill is widely used in powder making production line in industries‚ like mining‚ building materials and chemistry industries. It is a key equipment to grind all kinds of ores and other materials. The cement ball mill is composed of feeding part‚ discharging part‚ turning part and driving part (reducer‚ small driving gear‚ electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process
