- Q1The course or path that an object is moving on is itspositionaccelerationdirectionspeed30s7.P.1.1
- Q2Which of the following is an example of acceleration?An object at restAn airplane moving in a straight line at a constant speed of 500 mphA race car going through a curve (changing direction)A book laying on a table30s7.P.1.1
- Q3Using the distance/speed/time formulas here, solve this equation. An airplane travels at 200 meters in 8 seconds. What is its average speed?25 meters per second100 meters per second100 miles per hour25 miles per hour30s7.P.1.1
- Q4Mike, Jackie, Jeremy, and Niki were widely known to the be the fastest fifth graders at Robinson Elementary School. They wanted to know who is the fastest so they scheduled a race during recess. Their results are shown in the table. Who is the fastest student?JeremyNickiMikeJackie30s7.P.1.1
- Q5The diagram shows forces acting on a box. Which statement best describes what will happen to the box as a result of these forces being applied?The box will move to the rightThe box will move to the leftThe box will move upThe box will remain stationary (not move)30s7.P.1.2
- Q6John wants to build a racetrack that will allow his toy cars to travel fast when force is applied. Which material should he use?Gravel, because friction will be highSandpaper, because friction will be lowCarpet, because friction will be highPlastic, because friction will be low30s7.P.1.2
- Q7The image above shows two opposite forces acting on a box, what can we say that is true about the affect of the forces on the box?The box will move to the rightThe box will move to the rightThe forces are unbalancedThe forces are balanced. The box will not move.30s7.P.1.2
- Q8Which graph represents an object that is accelerating?BDAC30s7.P.1.3
- Q9Sally ran a distance of 8 meters in 16 seconds. The graph shows her motion. Which best describes her motion?Her speed was changingHer speed remained constantShe decreased her speed after four secondsShe stopped moving after four seconds30s7.P.1.4
- Q10In the distance vs time graph, each dot represents the end of a 30-minute interval. During which interval are the persons represented by the graph not moving?4.5 to 5 hours1.5 to 2 hours0 to 0.5 hours2 to 2.5 hours30s7.P.1.4
- Q11Based on the graph of a person going for a drive, which might describe the motion of the person?A person drives at a constant speed, then stops. He then continues in the same direction at the same speedA person drives at a steady pace, and then turns around and goes back home.A person drives very fast, then stops and rests. He then continues very slowlyA person drives up a hill, stops and then drives back down the hill30s7.P.1.4
