Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like km/h or m/s.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, e.g., 65 km/h south.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, indicating how quickly an object speeds up or slows down.

Front

How do you calculate average speed?

Back

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

Front

If a car travels 150 km in 3 hours, what is its average speed?

Back

50 km/h

Front

What two things must you know to determine speed?

Back

You must know distance and time.

Front

What is the formula for calculating acceleration?

Back

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

Front

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

Back

1 m/s²

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 a unit of velocity?

Back

Common units of velocity include meters per second (m/s) and kilometers per hour (km/h).
