Speed, Velocity, and Acceleration review

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, also measured in meters per second (m/s).

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

Is it true that low velocity means low acceleration?

Back

False. An object can have low velocity and still have high acceleration if it is changing its speed rapidly.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the starting point to the endpoint.

Front

If an object moves with a high speed, does it mean it has high acceleration?

Back

False. High speed does not necessarily indicate high acceleration; acceleration depends on how quickly the speed changes.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

If a motorcycle's velocity changes by 20 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = 20 m/s / 5 s = 4 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.
