Study Guide A Ch 16

How can motion be described?

Main Idea. The motion of an object can be described by its speed and direction. Speed and direction together determine an object’s velocity.

Fill in the blanks with words from the box below.

11

motion position gravity

velocity speed direction

1. ________________ is an object’s location, or place.2. ________________ is a change in an object’s position as compared to objects around it.3. ________________ is a measure of the distance an object travels in a certain amount of

time.4. Motion has both speed and ___________________.5. ___________________ is a measure of speed in a certain direction.6. Forces such as friction and ____________________ can change the velocity of moving

objects.

Circle the letter that best answers the question or completes the sentence.

7. Which is a change in an object’s position as compared to objects around it?A. direction C. speedB. motion D. velocity

8. Which measure of the distance an object travels in a certain amount of time?A. direction C. speedB. motion D. velocity

9. Which tells you which way an object is moving?A. direction C. speedB. motion D. velocity

10. Which is a measure of speed in a certain direction?A. speed C. motionB. velocity D. direction

Study Guide B Ch 16

What are gravity and friction?

Main Idea. Forces are pushes or pulls that cause objects to change their motion. Friction and gravity are two important natural forces.

Write answers to the questions on the lines below.1. What kind of force moves an object away?
