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, indicating how quickly an object is speeding up or slowing down.

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 (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving.

Front

What does a steep slope on a distance-time graph represent?

Back

A steep slope indicates a high speed of the object.

Front

What is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration.

Front

How can you tell if an object is accelerating from a velocity-time graph?

Back

If the slope of the line on a velocity-time graph is positive, the object is accelerating.

Front

What is the unit of acceleration?

Back

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