At a constant speed, acceleration is zero, but now there are three forces acting on the drone: the upward thrust force and the downward forces of gravity and air resistance.

A demonstration of key points of the required practical to investigate the effect of varying force or mass on the acceleration of an object for GCSE physics and combined science.

Force and Acceleration What about the acceleration of the car as it crashes into the wall? Here is a force diagram for the car while it is crashing.

Learn everything you need to know about forces to ace your science GCSE with this revision podcast from BBC Bitesize.

Newton’s Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” ...
