Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed refers to how fast an object is moving, measured as distance traveled per unit of 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 at which an object changes its velocity, which can involve speeding up, slowing down, or changing direction.

Front

Which of the following is NOT an example of acceleration?

Back

An object is in constant motion.

Front

If a car is traveling at 60 miles per hour, what is its speed?

Back

60 miles per hour.

Front

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

Back

It means the object is slowing down.

Front

How is acceleration calculated?

Back

Acceleration is calculated by the formula: (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

Give an example of velocity.

Back

A car driving 50 miles per hour north.

Front

What happens to the velocity of an object in free fall?

Back

The velocity increases due to the acceleration of gravity.
