Year 5 explore the relationship between Force, Mass and Acceleration

Thank you to Mr Dillard ( Head of Physics) for his work with year 5 on Forces and Motion. Students capture data to discover the relationship between these variables and test Newtons First law of Motion. ( see below).

Isaac Newton’s First Law of Motion states, “A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force.” What, then, happens to a body when an external force is applied to it? That situation is described by Newton’s Second Law of Motion. It states, “The force acting on an object is equal to the mass of that object times its acceleration.” This is written in mathematical form as:

Fma

F is force, m is mass and a is acceleration. The math behind this is quite simple. If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.
