Process Skills and Intro to Motion Flashcard Review

Front

Which of the following measurements is a scalar measurement?

Back

Time is a scalar measurement because it has magnitude but no direction.

Front

How close successive measurements come to each other is called:

Back

Precision refers to how close successive measurements are to each other.

Front

The total length of the PATH of motion is best described as____.

Back

Distance is the total length of the path of motion.

Front

What is a scalar?

Back

A scalar is a quantity described by magnitude only, without direction.

Front

Convert 0.15 m = _____ mm

Back

0.15 m is equal to 150 mm.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the initial to the final position.

Front

Define velocity.

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What does the term 'error' refer to in measurements?

Back

Error refers to the difference between the measured value and the true value.

Front

What is the significance of significant figures in measurements?

Back

Significant figures indicate the precision of a measurement and help convey the uncertainty in the value.
