Unit 3 Test Corrections- Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like km/h or mph.

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 of change of velocity of an object over time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What units are commonly used to measure speed?

Back

Common units include kilometers per hour (km/h) and miles per hour (mph).

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

If a car travels 100 miles in 2 hours, what is its speed?

Back

Speed = 100 miles / 2 hours = 50 mph.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed x Time.
