Distance and Displacement & Displacement vs. Time = Velocity

Question 1

What is distance?

Answer 1

It is a measure of motion. The unit is meters (m). It is not concerned with direction.

Question 2

What is a scalar?

Answer 2

It is a type of measurement that can be expressed with one piece of information.

Question 3

What is displacement?

Answer 3

It is also a measure of motion, and it is the change of position. It is a vector.

Question 4

What do vectors need? Using what formula?

Answer 4

Magnitude: trigonometry
Direction: pythagorean theorem

Question 5

What is the relationship in V=Δp/Δt=m/s

Answer 5

Velocity tells you how fast an object is moving and in which direction.

Question 6

1) Upward motion means…
2) Downward motion means…

Answer 6

1) positive change in position
2) negative change in position

Question 7

What does URM mean?

Answer 7

Uniform rectilinear motion meaning velocity is in a constant horizontal line.
V-T graphs have constant horizontal lines.
P-T graphs have straight lines.
