Motion: 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).

Front

What is velocity?

Back

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

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the formula to calculate distance?

Back

Distance = Speed × 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 does a flat line on a distance-time graph represent?

Back

A flat line indicates that the object is not moving; it has zero speed.

Front

If a car travels 1500 m in 50 seconds, what is its average speed?

Back

Average speed = Distance / Time = 1500 m / 50 s = 30 m/s.

Front

What does acceleration mean?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

How do you calculate time if you know distance and speed?

Back

Time = Distance / Speed.
