Speed and Velocity

Front

What is the definition of speed?

Back

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

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, also measured in meters per second (m/s).

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).

Front

If a car travels 60 km in 1 hour, what is its speed?

Back

Speed = Distance / Time = 60 km / 1 hour = 60 km/h.

Front

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

Back

A flat line indicates that the object is not moving (stationary).

Front

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

Back

A steeper slope indicates a higher speed of the object.

Front

How do you calculate distance when speed and time are known?

Back

Distance = Speed × Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down (deceleration).

Front

If an object travels 200 m North and then 100 m South, what is its total distance traveled?

Back

Total distance = 200 m + 100 m = 300 m.
