Physical Science Physics review

Boiling is the process where a liquid turns into vapor when it reaches its boiling point, which is the temperature at which its vapor pressure equals the external pressure.

Terminal speed is the constant speed that a freely falling object eventually reaches when the resistance of the medium (like air) prevents further acceleration.

Vector quantities are physical quantities that have both magnitude and direction, such as velocity and force.

Speed is calculated by dividing the distance traveled by the time taken. Formula: Speed = Distance / Time.

Kinetic energy is the energy that an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

At 0°C, water can either freeze into ice or remain in liquid form, depending on the surrounding conditions.

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Acceleration is calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Friction is a force that opposes the relative motion of two surfaces in contact, affecting the speed and acceleration of moving objects.
