Newton's Laws

Newton’s Laws

• Understanding motion principles and forces-objects relationships can be achieved by understanding Newton’s three laws.
• First law (law of inertia): An object will stay at rest or in motion at a constant velocity unless acted upon by an external force.
• Second law (F = ma): Presents the direct relationship between force and acceleration and the inverse relationship with mass.
• Third law: For every action or force, there is an equal and opposite reaction force.
• Knowledge and application of these laws are essential for mastering the Forces and Newton’s Laws part of the curriculum.
