#22.1
Know and understand the meaning of Newton’s three laws.
Includes applying the laws to problems.
Newton's first law Newton's second law for motion in a straight line Newton's third law
#22.3
Be able to formulate the equation of motion for a particle moving in a straight line when the forces acting are parallel or in two perpendicular directions or in simple cases of forces given as 2-D vectors in component form.
Including motion under gravity.
Notation:
\(F = ma\) where \(F\) is the resultant force.
\(\bold{F} = m\bold{a}\) where \(\bold{F}\) is the resultant force.
[Excludes: Variable mass]
Newton's second law for motion in a straight line Weight and motion in a straight line under gravity
#22.4
Be able to model a system as a set of connected particles.
e.g. simple smooth pulley systems, trains. Internal and external forces for the system.
#22.5
Be able to formulate the equations of motion for the individual particles within the system.
#22.6
Know that a system in which none of its components have any relative motion may be modelled as a single particle with the mass of the system.
e.g. Train.
#22.7
Be able to formulate the equation of motion for a particle moving in a straight line or in a plane.
Including motion under gravity.
Notation:
\(F = ma\) where \(F\) is the resultant force.
\(\bold{F} = m\bold{a}\) where \(\bold{F}\) is the resultant force.
