Lesson 2-5 Physics by TT

These are physical quantities that have magnitude only (and unit of measurement)

• The physical quantities that have both magnitude (how much) and direction (which way it is heading). (and unit of measurement)

If the rotation from +x-axis toward +y-axis, θ is

• positive

• negative

• invalid

• rotating

if the rotation is from +x-axis toward -y-axis, θ is

• positive

• negative

• invalid

• rotating

Which is NOT part of scalar quantities

• Time

• Temperature

• Velocity

• Mass

What is NOT part of vector quantities

• Velocity

• Force

• Torque

• Length

•  It is the actual path taken by an object with respect to the starting point.

• total;  xtot = x0 + x1

• Distance

• Position

• Displacement

• Speen

It has a magnitude equal to the object’s distance from the origin and has a direction determined by the object’s location with respect to the origin.

It is the change in position

This is the rate at which an object covers a distance.

•  m/s, km/h, mi/h
