The SI unit for force is

• meter

• newton

• kilogram

• pound

Balanced forces acting on an object

• always change the object's motion

• sometimes change the object's motion

• never change the object's motion

• are not related to motion

Air resistance is a type of

• motion

• acceleration

• velocity

• friction

Which of the following is an example of rolling friction?

• your shoes on a sidewalk as you walk

• bike tires on the road as you ride

• a boat on the water as it sails

• two hands rubbing together

When an object's distance from another object is changing

• it is in motion

• it is speeding

• it has a high velocity

• it is accelerating

Speed equals distance divided by

• motion

• velocity

• size

• time

When you know both the speed and direction of an object's motion, you know the

• average speed of the object

• acceleration of the object

• distance the object has traveled

• velocity of the object

On a graph showing the distance versus time, a horizontal line represents an object that is

• moving at a constant speed

• increasing its speed

• decreasing its speed

• not moving at all

A place or object used for comparison to determine if something is in motion is called

• position

• reference point

• a constant

• velocity
