The changes in speed, changes in direction, or changes in both
can described as what?
1. Speed2. Velocity3. Acceleration4. Instantaneous
speed
The ratio of the distance an object moves to the amount of time the object moves is what?1. Speed2. Velocity 3. Acceleration4. Instantaneous
Speed
When measuring speed in a specific direction, it is called
1. Velocity2. Speed3. Acceleration4. Instantaneous
Speed
Jack's speed on his bicycle as he went by school was 8 m/s and then at the stop light was 0 m/s. How would you describe his motion?
1. Staying constant2. Accelerating3. Decelerating4. Increasing velocity
Which of the following is the equation for speed?
1. S = d/t2. S = d * t3. S = Vf -Vi4. None of the
above
A horizontal line on a distance line graph means the object is

2. How fast a direction is changing at a specific instant
3. How fast a velocity is changing at a specific instant
4. None of the above
What is the shortest distance between the starting point and
the end point called?
1. Frame of reference2. Velocity3. Displacement4. All of the above
Which distance can be most accurately measured with a
ruler?1. The width of a
book2. The length of a
river3. The distance
between two cities
4. The size of an object under a microscope
What two variables are used to measure speed?
1. Distance & velocity
2. Distance & time3. Time & Velocity4. Final Velocity
and Initial Velocity
Velocity is a description of what two things?
1. Vector and time2. Speed and
distance3. Speed and
direction4. Distance and
