Speed Velocity and Acceleration

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 specific direction.

Front

What does a graph representing acceleration show?

Back

A graph representing acceleration shows how quickly an object's velocity changes over time.

Front

Why does a car accelerate as it rounds a corner at a constant speed?

Back

A car accelerates because its direction changes.

Front

True or False: Acceleration only takes place when things speed up.

Back

False. Acceleration can also occur when an object slows down or changes direction.

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 acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.
