Speed, Velocity and Acceleration Test

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, combining both speed and direction.

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

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a car travels 300 meters in 15 seconds, what is its speed?

Back

Speed = Distance / Time = 300 meters / 15 seconds = 20 meters/second.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

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

If a cyclist increases their speed from 10 m/s to 15 m/s in 5 seconds, what is their acceleration?

Back

Acceleration = (15 m/s - 10 m/s) / 5 s = 1 m/s².

Front

What is the unit of measurement for speed?

Back

The unit of measurement for speed is typically meters per second (m/s) or kilometers per hour (km/h).
