Physical Science Physics review

Front

What is boiling?

Back

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.

Front

What is terminal speed?

Back

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

Front

What are vector quantities?

Back

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

Front

How do you calculate speed?

Back

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

Front

What is kinetic energy?

Back

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.

Front

What happens to water at 0°C?

Back

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

Front

What is the difference between speed and velocity?

Back

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.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the principle of conservation of energy?

Back

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

Front

What is friction?

Back

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