Grade 8 Science Q4 - Force, Motion, and Energy
-featured.png)
This course covers kinematics, energy, and light through clear explanations, graphing practice, and guided experiments. Students master speed, velocity, acceleration, work, power, potential and kinetic energy, energy conservation, and reflection/refraction. Includes distance-time and velocity-time graphing, mirror and lens investigations, and a local case study on Philippine hydroelectric power to link theory with real-world applications.

What you'll learn
- Identify and describe examples of accelerating objects and define acceleration as the rate of change of an object's velocity.
- Construct, annotate, and interpret distance-time and velocity-time graphs to represent the characteristics of uniform and non-uniform acceleration.
- Recognize that work is done when a force causes the displacement of an object and describe kinetic energy as the energy of movement, relating power to the rate of doing work.
- Describe potential energy as energy stored due to position, explain mechanical energy, and describe the conservation of energy in everyday situations.
- Gather information and explain how the potential energy stored in the Philippines' lakes and dams is transformed into kinetic energy to generate electricity for local use.
- Carry out guided investigations to describe and illustrate the reflection of light using mirrors and the refraction of light using transparent materials, lenses, and prisms.
