Physics Ch 1

1. When an object’s distance from another object is changing (reference point to reference point),

• A it is in motion.
• B it is speeding.
• C it is accelerating.

2. Speed equals distance divided by

• A time.
• B motion.
• C velocity.

3. When you know both the speed and direction of an object’s motion, you know the

• A distance the object has traveled.
• B acceleration of the object.
• C velocity of the object.

4. The steepness of a line on a distance/time graph is called the

• A run.
• B the vertical axis.
• C slope.

5. The rate at which velocity changes is called (motion you can feel)

• A motion.
• B direction.
• C acceleration.

6. Which of these is an example of deceleration?

• A a car approaching a red light
• B an airplane following a straight flight path
• C a bird taking off for flight

7. Average speed is

• A the total distance traveled divided by the total time.
• B equivalent to velocity.
• C the rate at which an object is moving at a given instant.

8. If you know the distance an object has traveled in a certain amount of time, you can determine

• A the location of the object.
• B the acceleration of the object.
• C the speed of the object.

9. If the speed of an object does NOT change, the object is traveling at a

• A average speed.
• B increasing speed.
• C constant speed.

10. Changing direction (turning left or right, going up or down, etc) is an example of a kind of

• A speed.
• B acceleration.
• C velocity.
