By calculating the initial velocity, we can better understand factors like acceleration, displacement, and trajectory. In this article, we will explore four ways to find the initial velocity of an ...

(It's fewer since I use three position points for each velocity point.) Since the acceleration is the rate of change of velocity, I can then use the velocity values to find acceleration values.

Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to work out displacement.

The area under a velocity-time graph gives the displacement. The velocity-time and acceleration-time graphs for common motions are shown below.

The slope of the velocity graph during this time gives a vertical acceleration of 1.8 m/s 2. After that first part, the rocket slows down to so that it can stop rising.
