Front

Speed = _______________

Back

Distance / time

Front

Another word for distance divided by time would be what?

Back

Speed

Front

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

Back

500ft/sec west

Front

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

Back

Acceleration

Front

If my starting speed is 100mi/hr and my final speed is 0mi/hr I experienced acceleration. True or False?

Back

True

Front

What is the formula for calculating acceleration?

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 unit is commonly used to measure speed?

Back

Meters per second (m/s) or kilometers per hour (km/h).

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time without changing its speed.

Front

What is negative acceleration also known as?

Back

Deceleration.
