Unit 3 - Describing Motion

a place where the position has been given a value of zero.

• origin

• displacement

• distance

A change in position

• origin

• displacement

• distance

This gives direction and speed of motion.

• dusplacement

• velocity

• distance

• acceleration

This means that the speed and direction that an object travels remain CONSTANT.

• instantaneous velocity

• constant velocity

• average velocity

• relative velocity

The total displacement divided by the total time taken.

• instantaneous velocity

• constant velocity

• average velocity

• relative velocity

The velocity at one specific moment in time at one specific point in its path.

• instantaneous velocity

• constant velocity

• average velocity

• relative velocity

The velocity with respect to a frame of reference

• instantaneous velocity

• constant velocity

• average velocity

• relative velocity

A term used to describe the relationship between a moving object relative to a stationary object.

• relative velocity

• frame of reference

• acceleration

• displacement

The rate at which velocity changes is called:

• relative velocity

• displacement

• acceleration

• speed

What does the Δx mean in this equation?

(Select all that apply)

• "change in" distance

• x_f - x_i

• displacement

• time
