A force is a push or a ____. Force is measured in ____ (N). The resultant ____ on an object is the overall force acting on it. The resultant force on an ____ can be calculated by adding up all the forces ____. The direction of the forces must be taken into account. If there is a ____ force acting on a body, the ____ (speed in a given direction) will change. A change in velocity is known as ____. Acceleration tells you the ____ of change of velocity and is measured in metres per second squared. The equation that relates force, ____, and acceleration is: F = m × a. Rearranging this equation gives acceleration. The acceleration of an object is ____ (having the same or a constant ratio) to the resultant force on an object, and inversely proportional (related so that as one value goes up the other goes down) to the mass.
