Motion Detector Lab

My reflecion on the motion detector lab. You could take data points from the graphs made and apply them to the equasions we laened to find the variable that is not represented. To have zero acceleration and positive velocity because if you arrent going any faster but are still moving, you arrent going faster but you are still moving, giving you a positive velocity. The position and the velocity can be the same if you move away from the motion detector and aget faster at the same rate. Some of the graphs were bouncy because they we weren't moving at a consistent speed or acceleration. if the velocity is negative it means that you are moving towards the detector and if it is positive you are moving away.

Sports On the Moon

If you were playing catch with a softball on the moon it would be different. The acceleration due to gravity is 1.6 m/s squared, which is lower than the earths acceleration due to gravity which is 9.8 m/s squared. The ball would fall more slowly because of the lack of gravity although it would go the same speed, making it go a lot farther.. You would also need to use less force to lift the ball because Acceleration due to gravity is directly related to the force/weight.

Bernouli's law

My example of Bernouli's law requires a birthday card. You hold the card at each end so it looks like an upside down tent. Then you turn the card towards you so it looks like a "v" then you blow in between the two sides. The two sides of the card will stick together. When you blow in between the sides it creates lower pressure, pulling the sides together.
