Physics Concepts of Scalars and Vectors

Front

What does a magnitude involve?

Back

A magnitude involves a number and unit.

Front

What is a scalar value?

Back

A scalar value has only magnitude.

Front

What is a vector?

Back

A vector includes a magnitude and a direction, which can be notated using qualitative (e.g., north, south) or quantitative notations (-/+).

Front

What are scalar values involving motion?

Back

Scalar values involving motion include distance, time, and speed.

Front

What are vector values involving motion?

Back

Vector values involving motion include displacement, velocity, and acceleration.

Front

What are some commonly referenced scalar values?

Back

Commonly referenced scalar values include time, volume, mass, temperature, and energy.

Front

What is the head to tail approach?

Back

It is a process to find the resultant by scaling the vectors, aligning the tail of a vector with the head of the previous vector, and measuring the distance from the origin to the last point.

Front

How do you find average speed?

Back

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

Front

How do you find average velocity?

Back

Average velocity is the displacement traveled divided by the time elapsed for that frame of reference.

Front

What is instantaneous speed or velocity?

Back

It is the rate at which the position is changing at a specific time.
