22: Newton's laws of motion

#22.1

Know and understand the meaning of Newton’s three laws.

Includes applying the laws to problems.

#22.2

Understand the term equation of motion.

#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=maF = ma where FF is the resultant force. F=ma\bold{F} = m\bold{a} where F\bold{F} is the resultant force.

Excludes: Variable mass*

#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=maF = ma where FF is the resultant force. F=ma\bold{F} = m\bold{a} where F\bold{F} is the resultant force.

Excludes: Variable mass*
