Why do you always make a graph in physics lab? It's not just for fun, there is a reason. Here is an example.

Learn how to understand and model collisions including explosions in terms of momentum, velocities and the forces involved for Higher Physics.

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.
