Front

What is speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving, measured in distance per time (e.g., miles per hour, meters per second).

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the speed of an object in a specific direction (e.g., 88 m/s north).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly an object is speeding up or slowing down (e.g., turning left).

Front

What type of electromagnetic wave has a higher frequency than visible light?

Back

Ultraviolet waves have a higher frequency than visible light and a larger wavelength than x-rays.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its chemical composition (e.g., being black in color).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What is the relationship between speed, distance, and time?

Back

Distance = Speed x Time.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity as it indicates the path along which an object is moving, differentiating it from speed.
