C/D: DYNAMICS and VECTOR DYNAMICS

(Forces and two-dimensional dynamics)
Students will analyse forces acting on an object and predict their effects on it. Students will use the concepts of two-dimensional dynamics to analyse common situations.

Students will:

State Newton's laws of motion

Identify workplace and community situations involving Newton's three laws

Apply Newton's laws to common situations
Solve problems involving: force, mass, acceleration
Describe force as a vector quantity
Define gravitational field strength
Solve problems involving:

The force of gravity (weight)
Gravitational field strength
Mass

Solve problems involving:

Force of friction
Coefficient of friction
Normal force

Resolve a force into two orthogonal components
Determine the magnitude and direction of a force given its two orthogonal components
Determine the net force from two or more forces
Construct free-body diagrams for objects in various situations
Use free-body diagrams to solve problems involving balanced or unbalanced forces
Solve problems involving objects on inclines
