Module 2 Dynamics

Content Focus

Here we will begin to study forces on objects and related concepts of acceleration, mass, momentum and energy.

"The relationship between the motion of objects and the forces that act on them is often complex. However, Newton’s Laws of Motion can be used to describe the effect of forces on the motion of single objects and simple systems. This module develops the key concept that forces are always produced in pairs that act on different objects and add to zero.

"By applying Newton’s laws directly to simple systems, and, where appropriate, the law of conservation of momentum and law of conservation of mechanical energy, students examine the effects of forces. They also examine the interactions and relationships that can occur between objects by modelling and representing these using vectors and equations.

"In many situations, within and beyond the discipline of physics, knowing the rates of change of quantities provides deeper insight into various phenomena. In this module, the rates of change of displacement, velocity and energy are of particular significance and students develop an understanding of the usefulness and limitations of modelling."

Biblical Perspective

Activity in physics finds justification through the cultural mandate to subdue and replenish the earth (Genesis 1:28). Physics provides us with powerful tools that can be applied to us as God’s stewards in service for God and for our fellow humans. In this regard Physics has yielded many applications, e.g. modern communications, jet travel, and computers. These have not merely benefited humanity, but also have helped people to preach the gospel and so fulfil the Great Commission.
