Speed and Velocity

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in 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, expressed in units like meters per second (m/s) with a directional component (e.g., 25 m/s North).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between distance and displacement?

Back

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

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

If a car travels at a speed of 60 km/h for 2 hours, how far does it travel?

Back

Distance = 60 km/h x 2 h = 120 km.

Front

What is the unit of measurement for speed?

Back

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

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time, with speed on the vertical axis and time on the horizontal axis.

Front

What does a horizontal line on a speed-time graph indicate?

Back

A horizontal line indicates constant speed; the object is moving at the same speed over time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.
