Practice for Quiz #3: Scalars, Vectors, GUESS Method

The difference between a "vector" and a "scalar" is that a vector includes:

• velocity

• time

• displacement

• position

• direction

If a velocity is negative, it means the object could be traveling (mark all 3 choices that apply):

• left

• down

• forward

• backward

• up

If you walk 7m East then 4m West, what is your displacement?

• 3m East

• 11m West

• 4m East

• 7m West

• 0m East

Without solving the problem, what is "given" in the problem below (mark all that apply)? Problem - A cyclist travels East at a speed of 2.5m/s for 200s. What distance does the cyclist cover?

• t

• d

• g

• v

• a

Without solving the problem, what is "unknown" in the problem below (mark all that apply)? Problem - A girl cycles to school at a velocity of 2.5m/s East for 400s. How far is her school from home?

• v

• t

• a

• g

• d

Which of the following is a scalar quantity?

• Distance

• Velocity

• Displacement

• Force

Which of the following is a vector quantity?

• Speed

• Distance

• Displacement

• Mass

Which formula is used to calculate distance when velocity and time are known?

• d = v × t

• v = d / t

• t = d / v

• v = t / d

Which of the following is the correct SI unit for distance?

• meters (m)

• meters per second (m/s)

• Newtons (N)

• milliliters (mL)

Which term is measured in meters per second (m/s)?

• Distance

• Displacement

• Speed

• Force
