Motion, Distance, Displacement, Speed and Velocity: QC #1

Front

What is the primary difference between distance and displacement?

Back

Distance is how far an object has moved, while displacement is the distance and direction from the starting point.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed at a specific moment in time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

If a car travels 120 miles in 2 hours, what is its average speed?

Back

60 mph.

Front

What is the total distance and displacement if a cyclist travels 10 miles east and then 10 miles west?

Back

Distance is 20 miles, displacement is 0 miles.

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

Is speed a vector or scalar quantity?

Back

Speed is a scalar quantity.

Front

Can speed be negative?

Back

No, speed cannot be negative; it is always a positive value.

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 does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time.
