Calculating and Graphing 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, combining both magnitude and direction.

Front

What is the formula for calculating speed?

Back

The formula for calculating speed is: Speed = Distance / Time.

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line on a distance-time graph represents that the object is not moving (constant distance).

Front

What does a straight diagonal line on a distance-time graph indicate?

Back

A straight diagonal line indicates constant speed; the object is moving at a steady rate.

Front

What does a curve on a distance-time graph represent?

Back

A curve on a distance-time graph indicates acceleration or deceleration; the speed of the object is changing.

Front

How do you calculate the distance traveled if speed and time are known?

Back

Distance can be calculated using the formula: Distance = Speed x Time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, indicating how quickly an object is speeding up or slowing down.

Front

What is the unit of acceleration?

Back

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