GRAVITY EXPERIMENT

GRAVITY EXPERIMENT

Research
On Monday our teachers Miss. West and Mrs. Moala did an experiment. From the look of the start of the video I already knew that it was going to be based on gravity and weight. Also if you did not know weight is not the same. The reason why I think that weight is not the same it is because some things can be light and some things can be heave. Miss. West and Mrs. Moala was testing out weight and gravity was with sports balls. They used a big heavy basketball, a bouncy ball and one of those Christmas glass balls.

What I found out was that some parts of the video were about physics. Also strength or energy which is needed for something to move. Gravity is the force that pulls an object to a planet. The last thing that I found out was that force is the same as energy.

Hypothesis
When I watched the experiment, I thought that if both the sports balls were dropped at the same time and from the same height, then the basketball would drop first.

Procedure
As we were watching the video Miss. West and Mrs. Moala were asking question to each other and saying why one of the balls were going to drop first on the floor. Miss. West had chosen the heavy basketball and Mrs. Moala had chosen the little and light Christmas ball. They tested it out. When they both dropped it at the same time, Mrs. Moala's Christmas ball dropped on the floor and shattered all over the floor. After that they had to clean up all of the glass that smashed on the floor. Then they tested it again. When they tested it they both decided that Mrs. Moala would drop them both at the same time. When Mrs. Moala dropped it at the same time they both bounced on the floor at the same time. Also, there was a basketball, and a little bouncy ball.

Results
When Miss. West and Mrs. Moala tested the basketball and the Christmas ball. When they tested it the Christmas ball dropped on the floor before the basketball. But when they tested it again, they tested it with the basketball and a little bounce ball. But when they tested it with both balls they both dropped on the floor at the same time.

Conclusion
So the reason why on the first try the little Christmas ball hit the floor was that, that ball didn’t have any weight to it an because the basketball had a lot of weight on it. It also smashed on the floor because it was glass. So Miss. West and Mrs. Moala had to clean up all of the glass so that we don’t step on it. And the reason why on the second drop they both hit ground was because Mrs. Moala drop both sports balls at the same time and from the same height.

I hope you liked it. Please leave a comment thank you so much
