The kinetic energy you put into it will turn into potential energy. Ke=U. When it is falling all of the potential will turn into kinetic. h=15-1.7 for the first and 15 for the second.
Answers:
1) A process that occurs when an object or a particle moves, referred to as kinetic energy
2) A potential energy is a stored amount of energy that changes depending on the relative positions.
3) Potential Energy is the energy stored in an object due to its position. Kinetic Energy is the energy of motion in a moving object.
4)
a) C and B
b) A
c) From B to A or from C to A
d) From A to B or from A to C
Answer:
When the denominator of both ratios is the same, adding the ratio is simple. You just add the numbers to the left of the colon (this number is called the Ratio Numerator)xplanation:
The mean may be calculated by summing the values of the refractive index and dividing the sum by the number of experiments. This is:
Mean = (1.45 + 1.56 + 1.54 + 1.44 + 1.54 + 1.53)/6
Mean = 1.51
The mean absolute error is the sum of the absolute values of errors divided by the number of trials:
MAE = (|1.45-1.51|+|1.56-1.51|+|1.54-1.51|+|1.44-1.51|+|1.54-1.51|+|1.53-1.51|)/6
MAE = 0.043
The fractional error is the MAE divided by the actual value:
Fractional error = 0.043 / 1.51
Fractional error = 43/1510
The percentage error is the fractional error multiplied by 100:
Percentage error = 2.85%
