Acceleration (m/s²) = (final velocity - initial velocity (m/s)) ÷ time (s) a = (v - u) ÷ t

How can you increase acceleration?
1) Increase speed (velocity) with same direction e.g. speeding up on motorway 2) Change the direction but keep a constant speed e.g. satellite in orbit.

What is Newton's 1st Law?
An object at rest stays at rest, an object moving with a constant velocity stays at this velocity UNLESS EXTERNAL FORCES act on the objects.

What is the resultant force?
Overall force acting on an object after combining all forces: Driving force - Drag
