Learning outcomes

This course unit detail provides the framework for delivery in 21/22 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates

On completion successful students will be able to explain the role of, and solve problems involving, the following concepts: 

1. frame of reference and its associated coordinate systems. 

2. Newton's laws and the motion of simple systems. 

3. energy, work, power, momentum, force, impulse, angular velocity, angular acceleration and torque. 

4. conservation of energy, momentum, and angular momentum. 

Furthermore, they will be able to solve problems involving: 

5. the rotation of rigid bodies. 

6. motion in a gravitational field.
