Motion Review

An object traveling at a constant 20 m/s in a circular path is changing its

• speed

• momentum

• velocity

• mass

In 1.5 hours you walk 7.5 km. When you divide your distance by the amount of time it takes, you are calculating

• average speed

• instantaneous speed

• velocity

• acceleration

You are in Boston, Massachusetts. You decide to head south to Nashville, Tennessee. In one hour, you travel 100 km.

• 100:1

• 100 km/h

• 100 km

• 100 km/hr; south

Acceleration can be a change in

• speed

• velocity

• direction

• all of these

An example of acceleration is

• a car stopped at a red light

• a car turning a corner

• jogging in place

• a jet cruising on a straight path

This graph represents an object that is

• at a constant speed

• speeding up

• slowing down

• standing still

Tags

NGSS.MS-PS3-1

This graph represents

• positive acceleration

• negative acceleration

• constant speed

The rate at which velocity changes is called

• instantaneous speed

• direction

• acceleration

• motion

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

• average speed

• distance an object traveled

• acceleration of the object

• velocity of the object

Speed equals distance divided by

• time

• size

• velocity

• motion
