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

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

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
