WSR #2 Motion and Position Quizzizz

Aiden, Anika, and Harper are observing a toy car moving on a track. They are recording the car's position at different times. What kind of graph are they creating?

• They are creating a graph that shows the velocity of the toy car as a function of time.

• They are creating a graph that shows the distance traveled by the toy car as a function of time.

• They are creating a graph that shows the position of the toy car as a function of time.

• They are creating a graph that shows the acceleration of the toy car as a function of time.

Aiden, Mason, and Benjamin are conducting a physics experiment. They are tracking a toy car's movement on a track and have plotted a position-time graph. How can they determine the velocity of the toy car from this graph?

• Find the area under the position-time graph.

• Calculate the average speed of the toy car.

• Determine the acceleration of the toy car.

• Find the slope of the position-time graph.

Sophia and Anika are observing a position-time graph of a car driven by Olivia. What does a horizontal line on this graph indicate about Olivia's car?

• Olivia's car is at rest or not moving.

• Olivia's car is moving in a circular path.

• Olivia's car is accelerating.

• Olivia's car is moving at a constant speed.

Grace, Abigail, and Zoe are participating in a race. If Grace is running in a uniform or "constant" motion, how would you define her motion?

• Grace covers unequal distances in equal intervals of time.

• Grace covers equal distances in unequal intervals of time.

• Grace covers unequal distances in unequal intervals of time.

• Grace covers equal distances in equal intervals of time.

Avery, Nora, and Priya are participating in a race. If we want to calculate Avery's average speed during the race, which equation should we use?

• Average speed = (Avery's change in position) * (change in time).

• Average speed = (change in time) / (Avery's change in position).

• Average speed = (Avery's final position) / (initial position).

• Average speed = (Avery's change in position) / (change in time)

Grace, Ava, and Mason are racing their remote-controlled cars. If Ava's car is represented by a steep slope on a position-time graph, what does this indicate about her car's speed?

• low velocity or speed

• high velocity or speed

• constant velocity or speed

• negative velocity or speed

Elijah, Avery, and Benjamin are observing a position-time graph of a car's movement. They notice that the line on the graph is curved. What does this indicate about the car's movement?

• The car's velocity is changing.

• The car is accelerating in a straight line.

• The car is moving at a constant speed.

• The car is at rest.

Charlotte, Michael, and Arjun are participating in a race. Each of them is changing their speed at different points in the race. Can you identify which of the following examples represent their non-uniform motion?

• Charlotte sprinting at the start and then slowing down

• Michael riding a bicycle at different speeds

• Arjun driving a train that starts and stops at different stations

• Michael accelerating or decelerating his car

What is the difference between uniform motion and non-uniform motion?

• Uniform motion is when an object covers equal distances in equal intervals of time, while non-uniform motion is when an object covers equal distances in unequal intervals of time.

• Uniform motion is when an object covers equal distances in equal intervals of time, while non-uniform motion is when an object covers unequal distances in equal intervals of time.

• Uniform motion is when an object covers equal distances in unequal intervals of time, while non-uniform motion is when an object covers unequal distances in unequal intervals of time.

• Uniform motion is when an object covers unequal distances in equal intervals of time, while non-uniform motion is when an object covers equal distances in equal intervals of time.
