1st Semester POT Exam

Front

What is velocity?

Back

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

Front

How do you calculate distance using speed and time?

Back

Distance = Speed × Time.

Front

If a person walks for 7.5 hours at a speed of 12 miles/hr, how far do they travel?

Back

Distance = 12 miles/hr × 7.5 hours = 90 miles.

Front

What is the formula to find speed?

Back

Speed = Distance / Time.

Front

If a snail moves at 0.30 meters per minute, how far does it travel in 15 minutes?

Back

Distance = 0.30 m/min × 15 min = 4.5 meters.

Front

What is the speed of Ethan if he moves 10.7 m in 26.8 s?

Back

Speed = 10.7 m / 26.8 s = 0.4 m/s.

Front

How do you determine if acceleration has occurred?

Back

Acceleration occurs if there is a change in speed or direction.

Front

What is the speed of JW if he tumbles 30 m in 4.2 s?

Back

Speed = 30 m / 4.2 s = 7.1 m/s.

Front

What does it mean if a cyclist is riding at a constant speed?

Back

It means there is no acceleration because neither speed nor direction is changing.

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).
