The starting point used to describe the motion or position of an object.

• distance

• speed

• velocity

• reference point

The process of changing position.

• distance

• motion

• reference point

• speed

How is velocity different from speed?

• it includes the displacement of the object

• it includes the direction of the object

• it includes the distance of the object

• it includes the acceleration of the object

What is the formula to solve for the speed of an object?

• s=d/t

• s=d x t

• s=t/d

What is the formula to solve for distance of an object?

• d = s x t

• d = s/t

• d = t / s

What is the formula to solve for time of an object?

• t = s x d

• t = s / t

• t = d / s

When an object has a negative acceleration, it is:

• speeding up

• slowing down

• constant speed

When an object has a positive acceleration, it is:

• speeding up

• slowing down

• constant speed

• 0.0032 seconds

• 31.25 seconds

• 0.032 seconds
