Speed, Velocity, or Acceleration?

Front

What is Speed?

Back

Speed is the distance traveled per unit of time, regardless of direction. It is a scalar quantity.

Front

What is Velocity?

Back

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

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

How is Speed calculated?

Back

Speed = Distance / Time.

Front

How is Velocity calculated?

Back

Velocity = Displacement / Time.

Front

How is Acceleration calculated?

Back

Acceleration = (Final Velocity - Initial Velocity) / 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 happens to the speed of a roller coaster as it goes down a hill?

Back

The speed increases due to gravitational acceleration.

Front

What does it mean if an object has a negative acceleration?

Back

It means the object is slowing down.

Front

If a car travels 60 miles in 1 hour, what is its speed?

Back

Speed = 60 miles / 1 hour = 60 mi/hr.
