Motion Study Guide

The graph represents the relationship between the distance traveled and the time elapsed for an object in motion.Which of the following can be inferred from the graph?

• The object is moving along a curved path.

• The object moves at a constant speed.

• The object is experiencing acceleration.

• The object is experiencing negative acceleration.

Every few years, sailboats of different countries compete in a race for a trophy called the America's Cup. The boats sail over the same distance. What, besides the distance, is needed to find out the speed of each boat in the race?

• the time it takes each boat to finish the race

• the size of each boat in the race

• the skill of the crew of each boat in the race

• the speed of the wind during the race

Lola wants to measure her average speed when biking around her neighborhood. What information does Lola need to gather?

• distance traveled and direction

• bike weight and total time traveled

• bike weight and direction

• distance traveled and total time traveled

Alyssa did an experiment to study the motion of a moving object. First, she collected measurements of the total distance the object traveled at various times after the moment at which she began her observation. Then, she prepared a graph to plot the data she collected. The first data point that Alyssa recorded was at (2, 20), as shown in the graph below.

Assuming that the speed of the object that Alyssa observed was constant, which data point should Alyssa correctly plot next on her graph?

• (6,50)

• (4,40)

• (5,30)

• (3,40)

Todd and Angela set up a ramp and released several cars from the top. If Todd and Angela want to determine the average speed of their cars down the ramp, what information do they need?

• time down the ramp and acceleration from rest

• acceleration from rest and distance down the ramp

• direction of motion and time down the ramp

• distance down the ramp and time down the ramp

The graph shows distance versus time for an object.

Which of the following correctly describes the object's motion?

• The object is moving with increasing velocity.

• The object is moving with constant acceleration

• The object is moving with constant velocity.

• The object is moving with increasing acceleration.

Which of the following quantities is a velocity?

• 10 km/hr eastward

• 3 g/L in weight

• 25 m/s

• 15m/s²

The driver of a car completes a trip. The graph displays data about the car's motion during the trip.

Which of the following statements about the car's motion is true?

• The car did not slow down during the trip.

• The car returned to where it had started the trip at the end of the trip.

• The total time for the car trip was 50 minutes.

• The car did not travel at a constant speed during the entire trip
