1. You measure the Gravity constant which is g= 9.8 m/s2. If your experiment yields a value for g=8.85 m/s2, what is the percentage error in the value of g?

Expert Solution

To solve this problem you have to know about Error in physic

Step 1.

Definition: The measurement error is defined as the difference between the measured value and the true value . Affect any instrument and may be due to various causes. Which can somehow predict, calculate, removed by calibrations and compensations are called deterministic or systematic and relate to the accuracy of the measurements. Which can not be predicted because they depend on unknown causes, or stochastic are called random and are related to the accuracy of the instrument.

As stated earlier, we calculate the uncertainty of an experimental result in order to allow a meaningful evaluation of the agreement of that experimental result with an “accepted” value established by existing theory, or with the results of other experiments. We usually do this by comparing the % uncertainty of the experimental result either to the % error for that result, or to the % difference between the results of two or more different experiments. If a theoretically accepted value for the experimentally measured quantity is available, we compute the % error for our measured value, by taking the difference between the experimental value and the accepted value, dividing by the accepted value, and multiplying by 100.

An object of 4 kg (assuming the acceleration of gravity g = 10 m / s2 ) suspended from a spring causes the spring to stretch 2 cm downwards. The object is moved 3 cm down from from its equilibrium position in the positive direction of movement, then it is released with speed zero initial. Assuming that there is no damping and that the object is under external force equal to: 20cos4(t) (N) a) Formulate the initial value problem that...

On a planet, the acceleration due to gravity is only 7.2 m/s2. A person living on that planet throws a football at 10 m/s at an angle of 48 degrees to the horizontal. The person is standing, so the ball launches from an initial height of 1.8 meters above the ground. (Ignore any air resistance here.) What maximum height from the ground would the ball reach? What would be the flight time before the ball gets back to the ground?
