Speed, Velocity Acceleration, Graphs

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is velocity?

Back

Velocity is speed in a given direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.

Front

What is the unit of speed?

Back

The unit of speed is meters per second (m/s).

Front

What is the unit of acceleration?

Back

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

Front

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

Back

A flat line on a distance-time graph represents no motion.

Front

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

Back

A steep line indicates a high speed.

Front

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

Back

A curve indicates changing speed (acceleration or deceleration).

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).
