This force compresses the ball. The force that the ground exerts on the ball does work on the ball, since it is in the same direction as the displacement. The gravitational potential energy the ball has before it is dropped is converted into kinetic energy while the ball is falling and then into elastic potential energy as the force from the ground does work on the ball. But because the material the ball is made of is not perfectly elastic, friction converts some of the energy into thermal energy. The elastic potential energy stored in the ball when it has lost all its kinetic energy is converted back into kinetic and gravitational potential energy.
if you were varying the temperature of the ball, what would be suitable value for the maximum temperature? Should you make measurements every degree, every 5 degrees, every 10 degrees, etc. How could you change the temperature of the ball and measure the temperature? Should the heights be measured from the top, bottom or middle of the ball? In a real experiment, it is obviously not possible to stop the ball at the top of its bounce - so how could you measure the height of the bounce?
Because acceleration is a rate, it is measured of how fast the velocity is changing with respect to time of course. The key idea that defines acceleration is change. Whenever we change our state of motion, we are accelerating. A bowling ball that can accelerate fast has the ability to change its velocity pretty fast. A bowling ball that can go from zero to 5 mph in .5 seconds has a greater acceleration than another ball let go by another player that can go from zero to 7 mph in 1 second.
Bouncing Ball Experiment Our simple experiment is to drop a ping pong ball weighed at 3 grams from a height of 1 metre then 90cm, 80cm, 70cm, 60cm, 50cm, 40cm and of course zero cm. From dropping the ball we can see how high the ball will bounce to after having a loss or gain of energy due to sound or movement of the ball as it hits a hard surface. I will drop the ball 3 times altogether, on the second bounce I will look specifically at the point it is likely to bounce to so the results will be more accurate. After doing this three times I will then take an average to make it more accurate. This will then even out any freak results, which occur.
OK, now suppose you want to kick the ball so that it immediately starts rolling without slipping. How? You would give the ball "topspin" by striking the ball a distance (s) above an imaginary horizontal line that passes through the ball's center. But where? ANSWER: s=0.4R.
v= ¶19.6h v=velocity h=height t=¶2s s= distance a= acceleration t= time a Vt =distance In the prediction I can ignore the amount of time it takes to hit the floor as it will not change. In the final formulae only velocity will change so it has a direct correlation. As height is the only variable in the formula velocity also has a direct correlation. Therefore I predict that as height of the ball increases distance the ball travels will increase to. In the results I will make a graph with height the ball is dropped from on the axis and the formula ¶19.6h on the x axis and ¶2s a on the y.
It begins with gravitational potential energy which is continually transferred to kinetic energy as it accelerates towards the ground. Some energy is lost in the ball's flight downwards and upwards due to air resistance
The Factors that Affect the Height at which a Dropped Squash Ball Bounces Height-The higher the squash ball is dropped the higher it will bounce because there will be more energy converted into elastic energy to propel the ball back up. Type of Ball- The type of ball would greatly affect the experiment because different types of balls have different amounts of elasticity so some would bounce higher. Temperature of the Ball- The temperature of the ball would affect the experiment because the warmer the ball is the more energy and elasticity it will have. Landing Surface- Different types of surface will affect the bounce height because an elastic landing surface will absorb some of the energy, lowering the bounce height. However a rigid landing surface will absorb very little of the energy thus giving the ball a higher bounce height.
A second force is A spinning force that the C02 imparts on the ball causing a rotational acceleration and also a rolling motion. Once the ball has cleared the barrel there is a significant change in the forces that are acting on the paintball. The imbalance of the pressure behind the ball is gone. So that there is no longer any force pushing the ball in the direction that the muzzle is pointing in. It should be noted that there are many different ways that are employed to get a marker to shoot a paintball out of the marker.
Direction of the Initial Force For maximum impact, the bowler must release the ball with a force perfectly parallel to the horizon. Since the horizontal velocity is independent of the vertical velocity, an... ... middle of paper ... ... an elastic collision. The pins bounce against one another because their momentum is conserved during the collision(s). To achieve the most pin action, the bowler must put plenty of energy into the system and also find a direction of impact to efficiently distribute the kinetic energy. During pin action, some of the energy is transformed into sound.
