8 Physical Module 1 Test

What is a reference point in relation to the position of an object?

• The ending point of an object's position

• The starting point to describe the location of an object

• The midpoint of an object's position

• The highest point of an object's position

How is an object's position determined in 2 dimensions?

• By observing the color of the object

• By choosing a reference point and specifying directions

• By measuring the weight of the object

• By counting the number of objects around it

What is displacement in relation to motion?

• The process of changing position

• The total distance an object travels in a given amount of time

• The difference between the initial and final position of an object

• The speed and direction of a moving object

How is speed measured?

• By counting the number of steps taken by the object

• By measuring the temperature of the object

• By observing the shape of the object

• By calculating the total distance traveled divided by the total time taken

What is velocity in relation to motion?

• The difference between the initial and final position of an object

• The speed and direction of a moving object

• The process of changing position

• The total distance an object travels in a given amount of time

What does a graph show in relation to motion?

• The color of the object

• The shape of the object

• How an object's position changes during each time interval

• The weight of the object

Find the distance Sara walks from A to B,  B to C then C to D?

• 11m
• 3m
• 5m

After completing one trip on a roller coaster, the roller coaster's ________ is zero.

• displacement

• reference point

• length

• distance

The starting point you choose to describe the location, or position of an object

• Reference Point

• Distance

• Displacement

• Position

What is happening at A?

• Stationary
• Accelerating
• Slower steady speed; moving away from the starting position
• Steady speed; returning to start position
