... this line of code as “x becomes x plus v times delta t” So far so good for speed. But now we need to consider the concept of acceleration. We know that when a car accelerates, its speed changes. So acceleration is concerned with change in speed. That’s part of the definition, but not the whole story ...

Momentum and Impulse notes
... What does momentum and impulse have to do with each other? Momentum = mv If velocity changes, momentum changes, and acceleration (either + or –) occurs But we know: 1. for acceleration to occur, a force has to be applied. 2. If a given force is applied over a longer time, more acceleration occurs. ...

... (continued) • Equations of Motion If the forces can be resolved directly from the free-body diagram (often the case in 2-D problems), use the scalar form of the equation of motion. In more complex cases (usually 3-D), a Cartesian vector is written for every force and a vector analysis is often best. ...
