It looked like a medium sized dodgeball‚ but it was a lot softer than a dodgeball. The ball was big with rough diamond shaped patterns all across it. It felt smooth and it bounced up and down very easily. I asked my dad if I could play with the ball and he said yes. I would

Motion – Their Solutions 1. A place-kicker must kick a football from a point 36 m (about 40 yards) from the goal‚ and half the crowd hopes the ball will clear the crossbar‚ which is 3.1m high. When kicked the all leaves the ground with a speed of 20 m/s at an angle of 530 to the horizontal. 1. Does the ball clear or fall short of the crossbar? 2. Does the ball approach the crossbar while still rising or while falling? (a) From our equations of motion‚ the horizontal velocity is constant. This gives

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

This will assist each player individually and as a unit to improve both their individual and team skills. Don’t just stop with scheduled practices if you truly want to improve your skills and control on the court. On your own you can start by running dribbling drills. Remember to keep your weight on the balls of your feet

At any point in a game the most prevalent force acting upon both the player and the ball is gravity. Gravity can be seen influencing anything from a passed basketball

However‚ the exterior and interior of a basketball is the same regardless of what level it is played on‚ or what of type brand name the ball is. The exterior of a basketball is made of synthetic rubber‚ rubber‚ composition‚ or leather (“How products are made” 10/11/16). Every basketball is made out of one of these 4 coverings. The interior also contains something that every basketballs

considerable difference to the distance traveled and flight time of a ball. Air pressure is a vital aspect when considering distance traveled and flight time of a ball. If the force that is being applied to the ball remains constant‚ and the air pressure within the ball is the variable then we are able to draw a conclusion of how much difference the air pressure makes. If the air pressure within a ball is increased‚ then the gas within the ball becomes more elastic. Elasticity enables an object to release

However‚ as the experiment carried on‚ it was visible from the difference in composition of the mixture that viscosity had increased and a qualitative measurement of viscosity was best. The ball bearing was only able to pass through the least viscous times of the mixture: after the total addition of PVA and after
