Check definition, SI unit and formula for acceleration. Acceleration is one of the most important topics of Physics and questions based on this topic are often asked in school and competitive exams.

The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

We can't say because there is insufficient information. A direction is required before we can describe the force properly. Displacement is a distance and a direction, eg \(170m\) south. Velocity is a ...
