## Course unit details:Dynamics

Unit code PHYS10101 10 Level 1 Semester 1 No

Dynamics

### Pre/co-requisites

Late penalties for weekly Mastering Physics quizes

The weekly online quizzes will each contribute 1% of the marks when answered to a sufficient level (mark >40%). Late penalties apply as implemented in the software.

### Aims

To introduce the fundamental concepts of Newtonian mechanics.

### Learning outcomes

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.
