Projectile motion practical (1 Viewer)

[mkv_86]

For the practical for projectile motion, how would I improve the reliability, validity and accuracy?

Much thanks

Reliability = repeat it 4 more times, depending on what prac you did you could average results, do line of best fit

Accuracy = accuracy of measurement tools, how close your values are to the predicted ones

Validity = did your method answer the aim, control, controlled variables

Depends on what prac you did but those are the general ideas
