Newton`s 2nd Law Note
... An increase or decrease in speed, or a change in direction of an object’s motion. (change in velocity) / (time) V units = m/s/s = m/s2 t Most people would say 10 m/s2 is a fast acceleration and 1 m/s2 is a slow acceleration but it is more correct to say “large” or “small” in place of the words fas ...

Force and Newton`s First Law
... When the only force acting on an object is gravity, the object is said to be in free fall On earth, this is 9.8 m/s2 - Gravity constant In the absence of air resistance, all objects on Earth accelerate at the same rate, regardless of their mass. An object reaches its terminal velocity when the force ...
