Unit B: Changes in Motion
Themes: Change, Energy and Systems
Overview: Motion is an important aspect of our lives, and the understanding of the effects of force on motion has many technological applications Students learn that these application can range from the design of safer roads and sports equipment to the investigation of traffic accidents. In this unit, students investigate the concepts of displacement, velocity, acceleration, force, momentum and mechanical energy and consider the relationships among them.

- Grade 8 Science, Unit D: Mechanical Systems
- Science 10, Unit B: Energy Flow in Technological Systems
Course Focus: We will spend ~25% of the course on this unit.
Students Will:
- Describe one-dimensional motion of objects in terms of displacement, time, velocity, and acceleration.
- Describe and analyze the law of conservation of momentum for one-dimensional collisions and change in momentum (impulse) to explain how force affects motion.
Key Concepts:
- displacement, time, velocity, acceleration
- conservation of momentum in one dimension
- impulse and force
- Newton's laws of motion
- application of laws of motion and principles of momentum in the design of sports equipment and transportation safety devices.
