Objects in free-fall on the earth should experience an acceleration of 9.81 m/s². One of the kinematic equations that was presented earlier in this lab, d= Vot + 1/2at2, can be used to determine the acceleration of the spheres. C Balls Distance (m) Time (s) Acceleration in m/s?

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
