1.1. Particle motion in a straight lineAcceleration measures how quickly velocity changes. In physics, acceleration is defined as the rate of change of velocity with respect to time.1.2. Forces acting on a particleA force is anything that causes a body to accelerate. In other words, it changes the body's speed or direction.1.3. Stretching and compressing objectsHooke's law states that the restoring force in an elastic material is directly proportional to displacement within its limit of proportionality:1.4. A work-energy model for analysing particle motionIn everyday speech, work means any kind of mental or physical exertion. In physics, it has a precise mechanical meaning.1.5. Forces acting in a gravitational fieldIllustrated explanations.1.6. Uniform circular motionTo analyse circular paths, we measure rotation using angles in radians rather than degrees.
