Linear Motion & Graphing BASICS

Distance is

• the total path taken by an object

• Always equal to zero

• The difference in position of an object

• A vector quantity

Displacement is

• the total path taken by an object

• always equal to zero

• the difference in position of an object

• a scalar quantity

A person starts driving and travels 3 km east to the store, then turns around and travels 1 km west. What is the displacement of this person?

• 4 km

• 3 km

• 2 km

• 1 km

A person starts driving and travels 3 km east to the store, then turns around and travels 1 km west. What is the total distance traveled by this person?

• 4 km

• 3 km

• 2 km

• 1 km

True or False. When a car rounds a corner at a constant speed, its acceleration is zero.

• True

• False

Suppose you take a trip that covers 24 meters in 4 seconds. What is the average speed of you trip?

• 6 m/s

• 8 m/s

• 2 m/s

What does the slope of a velocity vs time graph represent?

• Velocity

• Acceleration

• Displacement

What does the slope of a position vs time graph represent?

• Velocity

• Acceleration

• Distance

If there is no slope shown on a velocity vs time graph (just a horizontal line) what does this tell you about the object?

• The object is moving at a constant acceleration

• The object is moving at a constant velocity

• The object is not moving at all

If there is no slope shown on a position vs time graph (just a horizontal line) what does this tell you about the object?

• The object is moving at a constant acceleration

• The object is moving at a constant velocity

• The object is not moving, v = 0 m/s
