Speed, Velocity & Acceleration

Front

What is speed?

Back

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

Front

What is acceleration?

Back

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

Front

Acceleration can be classified as _______________

Back

All of the above (Speeding up, Slowing Down, Changing directions)

Front

What is the formula to calculate speed?

Back

Speed = distance/time

Front

What does a constant speed graph look like?

Back

A straight line on a distance-time graph.

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 the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = distance/time = 100m/5s = 20 m/s.

Front

What does it mean if an object is accelerating?

Back

It means the object is changing its velocity, which can involve speeding up, slowing down, or changing direction.

Front

What is a negative acceleration?

Back

Negative acceleration, or deceleration, occurs when an object slows down.
