Lilja Test Practice - 4 - Graphing Speed, Acceleration, etc.

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 acceleration?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What unit is used to measure velocity?

Back

Velocity is measured in meters per second (m/s).

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

How do you calculate distance using speed and time?

Back

Distance = Speed x Time.

Front

What is the average speed of an object?

Back

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

Front

If a runner completes a 100 meter dash in 10 seconds, what is her average speed?

Back

10 m/s.

Front

What is the unit of measurement for acceleration?

Back

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