Revise Newton's three laws of motion using simple experiments, diagrams and example questions to show the link between forces and the bodies they act upon.

Newton's laws pertain to the motion of massive bodies in an inertial reference frame, sometimes called a Newtonian reference frame, although Newton himself never described such a reference frame.

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

For National 4 Physics use Newton’s Laws of Motion to describe how forces act on objects in motion; at rest; in freefall and in collisions.
