Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in units like meters per second (m/s) or kilometers per hour (km/h).

Front

What is velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly an object is speeding up or 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 car travels 100 km north in 2 hours, what is its velocity?

Back

Velocity = 100 km / 2 hours = 50 km/h north.

Front

What is an example of constant speed?

Back

A car traveling at 60 km/h on a straight highway without changing speed.

Front

What is an example of acceleration?

Back

A car increasing its speed from 20 m/s to 30 m/s in 5 seconds.

Front

What does a negative acceleration indicate?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.

Front

What is the unit of acceleration?

Back

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