Speed and Velocity

Front

What is the formula to calculate speed?

Back

S = d/t

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.

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 in 2 hours, what is its speed?

Back

50 km/h

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/h).

Front

What does a speed vs. time graph represent?

Back

It shows how speed changes over time.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.

Front

If a runner completes a 400 m lap in 50 seconds, what is their speed?

Back

8 m/s

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating average speed?

Back

Average speed = total distance / total time.
