Calculations

1. V1 = d / t1
Length of the glider: 10 centimeters
10 centimeters = .1 meters
.1 / 0.230 = .435 m/s

2. V2 = d / t2
Length of the glider: 10 centimeters
10 centimeters = .1 meters
.1 / 0.091 = 1.11 m/s

3. KE1 = ½ MV2
The mass of the glider on a pan parallelism: 189.3 grams
100 grams added to the glider.
Length of the glider: 10 centimeters
½ (100 g + 189.3 g / 1000) (.435)2
½ (.289300) (.189225)
.027371 J
.027 J

4. KE2 = ½ MV2
The mass of the glider on a pan relief: 189.3 grams
200 grams added to the glider.
Length of the glider: 10 centimeters
½ (200 g + 189.3 g / 1000) (1.11)2
½ (.389300) (1.232100)
.239828 J
.240 J


5. W = ½ M (Vf 2 Vi2 )
½ (189.

Questions

1. What force does the work? Kinetic energy is the force that does the work.

2. What are the possible sources of error in this experiment Some possible errors in experiment fin: students not setting the mode of the photogate to gate, not spell the air blower for the track to maximum power, nor remembering the dose to release the glider for all(prenominal) different trials (same point for each different trials).

A car driving thirty miles per hour, a pitcher throwing a baseball ten miles per hour, an athlete test fifteen miles per hour, all three different situations are examples of energising energy. Kinetic energy is defined as the energy of motion, the...If you call for to get a full essay, order it on our website: Orderessay
