Fundamentals of Force and Motion

📋 Course Outline

1. Force: push and pull effects
2. Motion: rest and motion states
3. Newton’s first law and F equals ma

📖 1. Force: push and pull effects

🔑 Key Concepts & Definitions

• Force : Force is a push or pull applied to an object that can change how it behaves.
• Push effect : Push effect is a force action that drives an object away from the point of application.
• Pull effect : Pull effect is a force action that draws an object toward the point of application.

📝 Essential Points

• Force can start motion in an object that was at rest.
• Force can stop a moving object.
• Force can change speed, including speeding up or slowing down.
• Force can change direction of motion.
• Force can change an object’s shape.

💡 Memory Hook

Push or pull = force; if behavior changes (speed, direction, shape), a force acted.

📖 2. Motion: rest and motion states

🔑 Key Concepts & Definitions

• Motion : Motion is the state of an object changing its position relative to its surroundings.
• Rest : Rest is the motion state where an object stays in the same position.
• Motion state : Motion state is the classification of an object as either at rest or moving.
