Speed and Velocity

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the formula for calculating distance?

Back

Distance = Speed × Time.

Front

What is the difference between speed and velocity?

Back

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

Front

What does a flat line on a distance-time graph represent?

Back

A flat line indicates that the object is not moving.

Front

What does a steeper slope on a distance-time graph indicate?

Back

A steeper slope indicates a higher speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the unit of acceleration?

Back

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

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.
