Speed Velocity and Acceleration

Front

What is speed?

Back

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

Front

What is the formula to calculate speed?

Back

Speed = distance/time

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What unit is acceleration measured in?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

If an object is moving at a constant speed, what is its acceleration?

Back

The acceleration is 0 m/s².

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

How do you calculate acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time.

Front

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

Back

A flat line indicates that the object is moving at a constant speed.
