Final answer:
In Physics, determining how high a ball went above its original point involves using kinematic equations and energy conservation principles. By considering initial launch conditions and the acceleration due to gravity, one can calculate the maximum height the ball reaches. Loss of height upon bouncing can be explained by the loss of kinetic energy during inelastic collisions.
Step-by-step explanation:
The question 'How high above its original point did the ball go?' relates to the field of Physics, specifically to the subsection of mechanical physics dealing with projectile motion and energy conservation. When a ball is thrown vertically upward or launched at an angle, its motion can be analyzed using kinematic equations. The height it reaches above its original point can be determined from the initial launch conditions, such as the speed and angle of launch, and the acceleration due to gravity, which is typically -9.81 m/s2 in the downward direction.
To calculate the maximum height reached by a ball thrown upwards, we can use the kinematic equations that relate initial velocity, final velocity (which will be 0 m/s at the highest point), acceleration, and the displacement. This can be done in a step-by-step manner taking into account the ball's initial velocity at launch and the distance the ball travels before reaching the maximum height.
When considering an object like a rubber ball bouncing off the floor, the concept of energy conservation is important. The ball loses kinetic energy during the collision due to factors such as heat and sound resulting from the impact, which explains why the ball only reaches 90% of its original height after the bounce. This loss of energy is tied to inelastic collision concepts.
