Study Notes

Key Physics Terms and Concepts

Acceleration: Rate of change of velocity; indicates how quickly an object speeds up or slows down.
Agent: Refers to natural forces or objects that produce specific effects or outcomes.
Archimedes' Principle: States buoyant force on a submerged object equals the weight of fluid displaced, crucial for understanding buoyancy.
Balanced Force: Equal forces acting on an object in opposite directions, resulting in no change in motion.
Center of Gravity: The specific point where an object's weight is evenly distributed, affecting stability and balance.
Centripetal Force: Force directing an object toward the center of a circular path, crucial for circular motion.
Chemical Energy: Energy stored in chemical bonds; potential energy that can be released during reactions.
Electrical Energy: Form of energy resulting from the movement or arrangement of charged particles, fundamental in circuits.
Force: A push or pull acting on an object; can cause changes in motion or shape.
Free Fall: Describes the motion when only gravity acts on an object, resulting in a weightless state.
Friction: The resistance encountered when two surfaces interact, opposing motion between them.
Gravity: Universal force of attraction between two objects based on their mass and distance.
Inertia: The property of matter that causes it to resist changes in its state of motion; greater mass means greater inertia.
Kinetic Energy: Energy possessed by an object due to its motion, dependent on mass and velocity.
Law of Conservation of Energy: Principle that energy can neither be created nor destroyed, only transformed from one form to another.
Mass: Quantity of matter in an object; defines the object's resistance to acceleration.
Mechanical Energy: Total energy of an object due to its motion (kinetic) and position (potential).
Momentum: Quantity derived from multiplying an object’s mass by its velocity; indicates the object’s motion characteristics.
Net Force: The resultant force acting on an object from the vector sum of all individual forces; determines acceleration and motion.
Newton's 1st Law: Law of inertia; an object remains in its current state (at rest or in uniform motion) unless compelled by an unbalanced force.
Newton's 2nd Law: Acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass (F = ma).
Newton's 3rd Law: For every action, there is an equal and opposite reaction; explains interaction between objects.
Potential Energy: Energy stored in an object due to its position or arrangement, often convertible to kinetic energy.
Power: Measure of the rate at which work is done or energy is transformed over time.
Projectile: Any object that is thrown or projected into the air, influenced by gravity and possibly other forces.
Receiver: Device meant to detect electromagnetic waves; plays a key role in communication technologies.
Speed: Measure of how fast an object moves, calculated as distance traveled over a specific time frame.
Thermal Energy: Total energy (kinetic and potential) possessed by particles within an object, related to temperature.
Unbalanced Forces: Forces that lead to a net force greater than zero, thereby causing a change in an object’s motion.
Velocity: Speed of an object in a specific direction; provides both magnitude and direction for motion analysis.
Weight: Force of gravity acting on an object, generally dependent on its mass and the local gravitational acceleration.
Work: Action of force causing displacement; defined as the product of force and distance moved in the direction of the force.
