What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units like meters per second (m/s) east.

Front

What is acceleration?

Back

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

What are the units of velocity?

Back

Velocity is measured in units like meters per second (m/s) with a direction, e.g., 50 m/s east.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a car travels 100 km in 2 hours, what is its speed?

Back

Speed = 100 km / 2 hours = 50 km/h.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

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

Front

How is average speed calculated?

Back

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