Speed, Velocity, & Acceleration

Front

(Final speed - Initial Speed) / time = __________________

Back

Acceleration

Front

Speed = _______________

Back

Distance / time

Front

Another way to explain the speed and direction of an object would be to describe its ________

Back

Velocity

Front

This occurs when an object speeds up, slows down, or changes direction.

Back

Acceleration

Front

If a plane is flying west at a speed of 500 feet per second. What is its velocity?

Back

500ft/sec west

Front

What is the definition of speed?

Back

The distance traveled per unit of time.

Front

What is the formula for calculating velocity?

Back

Velocity = Distance / Time + Direction

Front

What does acceleration measure?

Back

The rate of change of velocity over 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 acceleration of an object if it moves at a constant speed?

Back

The acceleration is zero.
