What is the best way to make sure an experiment is precise?
Ensure that measurements are taken carefully and consistently, minimize sources of error by controlling variables, use appropriate equipment calibrated regularly, and take multiple trials to calculate an average for more accurate results.
If a train travels 890 km and then overshoots the track 10 m what is the percent error in the total distance covered?
To calculate the percent error, first convert the overshoot in meters to kilometers (10 m = 0.01 km). Then, find the total distance covered by the train (890 km + 0.01 km). Calculate the percent error by finding the difference between the actual and measured distances, dividing by the actual distance, and multiplying by 100. The percent error can be then determined.
If error in the measurement of momentum of a particle is 100 percent then the error in the measurement of kinetic energy is what?
p=mv %errror in p= %error in m+%error in v lowest value of m=0 hence %error in velocity=100% k.e=%error in mass=2*%error in velocity K.E=200% similarly K.Eminimun=100% total error in K.E = 100+200 =300 hence error in ke = 300%
Why do you take many trials for a experiment?
Many trials are taken in an experiment as a way to limit experimental error. For example, if you are timing how long it takes a ball to roll down an angled track, as a human being you might release the ball at the wrong time, or push the stop button on the timer early or late. By running multiple trials and averaging the results, these errors should balance themselves out and give a better result.
How to calculate the error between two values?
To calculate the error between two values, subtract the smaller value from the larger value and take the absolute value of the result.
What can you ignore when you calculate percent error?
plus and minus signs
When you calculate percent error you ignore what?

Why is it important for scientists to calculate percent error?
To determine how right or wrong their answer is.
How do you calculate percentage error for density of pennies?
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.
Write the equation used to calculate percent error?
Percentage error = Value experimental-Value acceptedValueaccepted x 100

Why calculate percent error after doing an experiment?
Because then you can assess how valid your results are =D
Why is important to perform several trials of an experiment?
becase it reduces the percent error and it gives a much better idea of what is the best result
