height Ball bounces

Hypothesis

d81088395 — 2025-09-17 00:39:48 UTC

If I drop the ball at a specific height, then the ball will increase the height. But if I drop the ball at a lower height than the first height, the ball will decrease more height and bounce less.The ball will still increase its height but only in a higher drop because of gravity, the ball will get pulled up and bounce the highest.

dependent variable

almadia3132 — 2025-09-17 00:40:19 UTC

the hight the ball can bounce

jingbochen3132 — 2025-09-17 00:40:25 UTC

how does the height affect the bounces

If I drop the ball at height A, then it will bounce less than heights B and C because there is less momentum and less energy. So the ball bounce height will decrease

How does the height you dropped from affect the height of the ball bounce

2025-09-17 00:40:29 UTC

How does the drop height affect the ball bounce?

2025-09-17 00:40:31 UTC

Hypothesis

2025-09-17 00:40:40 UTC

If the drop height of a ball is at height A which is the highest point , then the ball bounce will be a little higher than height B which is the lowest because the energy and the force of gravity on height A will increase and make the ball bounce higher.

How does the height you dropped from affect the height of the ball bounce

2025-09-17 00:41:41 UTC

If I dropped the the ball 10cm then the ball would bounces 4cm because the force will increase that will let the ball bounces more higher

Controlled Variables

2025-09-17 00:41:41 UTC

-same floor texture

-same ball

-same strength

chacechai3132 — 2025-09-17 00:42:08 UTC

If I drop the ball from 5 cm and I increase it ,then will it all bounce higher then 5 cm because the higher you drop it the force will be bigger and that will send it higher up

If I drop the ball somewhere really high, it will get less energy .and get shorter and shorter

chacechai3132 — 2025-09-17 00:44:43 UTC

-The same ball

-Same force

-Same surface

-same person

Hypothesis

2025-09-17 00:44:56 UTC

If I drop the ball from the highest point, then it will bounce back the highest because the force gets stronger when I drop it higher.

jingbochen3132 — 2025-09-17 00:45:18 UTC

If I drop the ball from higher place the ball so it will higher

almadia3132 — 2025-09-17 00:47:09 UTC

if i put the ball more higher it will bounce more higher then the old drop

zhangmichelle3132 — 2025-09-17 00:48:42 UTC

jingbochen3132 — 2025-09-17 00:48:47 UTC

same place

same strength

same ball

Hypothesis

justinsun3132 — 2025-09-17 00:49:50 UTC

If I increace the height and drop the ball at point A, then it will bounce the heighest because point A have increased force transferred back to the ball and point B and C have decreased force.

2025-09-17 00:49:51 UTC

The same ball

Same surface

2025-09-17 00:49:55 UTC

If I drop ball in higher place then it will bounce more high because it is higher, and if I drop the ball lower it will have no energy to bounce higher

2025-09-17 00:50:22 UTC

same ball, same surface, same strength

2025-09-17 00:52:05 UTC

Same type of the ball, same place, same person

2025-09-17 00:52:27 UTC

If I drop the ball in the higher place then the ball bounce higher at the lower place because the energy is increasing.

If I drop the ball from a higher place, then it will bounce higher than a lower place

If I drop the ball from 10cm place, then it will bounce higher than 5cm place

by increasing of hight.

The dependent variable is the height of the ball bounce.

Research Question

elutd — 2025-10-14 08:35:49 UTC

How does the height of the ball dropped affect the height of the ball bounces?

Hypothesis

elutd — 2025-10-14 08:47:50 UTC

If the ball is dropped from higher height to a hard surface then, it will bounce higher because when it’s dropped from a shorter height the energy will be changed to heat and sound and the ball need a harder surface to push it back hardly and make them bounce high.

CV
