Finn-Science Midterm Part 1

What is an object's distance and direction from a reference point?

• displacement

• position

• reference point

• motion

When a reference point changes what two other factors must change?

• distance and direction

• distance and speed

• speed and direction

• velocity and direction

What is the process of changing postion?

• velocity

• direction

• motion

• reference point

The difference between the initial position and final position of an object is called...

• direction

• distance

• reference point

• displacement

A measure of the distance an object travles per unit in time.

• Speed

• distance

• velocity

• displacement

The rate of change of position in which the SAME distance is travled each second.

• constant speed

• instantaneous speed

• changing speed

• speed

The speed AND direction of motion

• motion

• constant speed

• speed

• velocity

The change in position or displacement divided by the time intervals in which the displacement occurs

• reference point

• speed

• velocity

• average velocity

A measure in the change in velocity during a period of time.

• velocity

• acceleration

• speed

• displacement

A change in velocity during a time interval divided by the time interval during which the velocity changes

• acceleration

• average acceleration

• velocity

• average velocity
