Study Notes
Nuclear Decay and Reactions
- Alpha decay involves the emission of a helium nucleus, consisting of two protons and two neutrons.
- Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.
Nuclear Fission vs. Fusion
- Nuclear fission is the splitting of a heavy nucleus into smaller nuclei, accompanied by the release of energy.
- Key difference: Fission involves breaking apart, while fusion involves combining nuclei.
Impulse and Force in Collisions
- Impulse is the product of average force and the time duration of a collision.
- Impulse changes an object's momentum, showing a direct relationship between impulse and average force.
Electrostatic Forces
- Forces between two charges of the same sign (positive-positive or negative-negative) repel each other.
- The direction of the force is away from each other, demonstrating Coulomb's Law.
Motion and Rotation
- Linear speed is the distance covered per unit time, while angular velocity measures the rate of rotation around a center point.
- Relationship: Linear speed = angular velocity × radius.
Centripetal Force
- Centripetal force is required for circular motion and can be provided by various forces such as tension, gravity, or friction.
- Any force that doesn't act towards the center of the circular path is NOT considered centripetal force (e.g., gravitational force on an object not in a circular path).
Period and Frequency Relationship
- The period of a wave is the time taken for one complete cycle, while frequency is the number of cycles per second.
- They are inversely related: Frequency = 1/Period.
Types of Waves
- Longitudinal waves consist of compressions and rarefactions, with particle movement parallel to wave direction.
- Transverse waves have particle movement perpendicular to wave direction, creating crests and troughs.
