How does a Ticker tape timer compensate friction?
It doesn't. This is a source of experimental error in tickertape experiments. Eg, if you are attempting to measure the acceleration due to gravity (g), a ticker tape experiment with large amounts of friction will yield values of g less than 9.8 m/s2. This is because frictional forces will oppose the motion - which is driven by the force downwards due to gravity. Hence the overall force on the moving object (tickertape included) will be less than the gravitational force, and hence the observed acceleration will be less than that due to gravity (g) - due to the slowing affect of the friction.
Discuss the validity of extrapolating the acceleration value to an angle of 90?
Extrapolate the experimental values of acceleration, vs. angle of the incline, to find the acceleration when the angle of inclination = 90 degrees. The acceleration at 90 degrees will equal 9.81 m/s/s, since this is the free-fall acceleration.
What are the factors that affected the difference between theoretical and experimental values?
mostly, how good your theory is. Remember, experimental values are from reality.
What is a measure of gravitational force of an object?
meters per second squared (m/s^2) the gravitation acceleration, acquired by experimental values =-9.8m/s^2. negative since its falling
What is numbers which are the results of an experiment?
These are the experimental values.
What is the result of an experience called?
These are the experimental values.
What is the definition of Experimental value?
the values you actually get when you do the procedure, these are then compared to the standard values
Are the values of experimental and theoretical probability same?
Absolutely not. Experimental is practical and theoretically anything is possible.
Do experimental measurements give the true value of physical quantity?
No because there are always experimental errors, instrument limitations, and deviations in measurements. This is called the uncertainty. Experimental values do not give true values but rather a value with an uncertainty.
Do the experimental and theoretical values of voltages and currents agree?
No
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
How do you get the experimental value of a rectangle?
A rectangle has no value - experimental or otherwise. Its area has a value, its perimeter, its aspect have values.
