Motion

Speed is 

• distance x time
• distance / time
• time x distance
• time / distance

Devin travels east 20 meters and then west 5 meters... What is his displacement from the starting point?

• 25 meters
• 20 meters
• 15 meters
• 5 meters

What would be the total displacement of a race car that wins the Daytona 500?

• 500 miles
• 250 miles
• 1000 miles
• 0 miles

On a distance vs time graph... the x axis is usually... 

• distance
• time
• vertical
• not used

On a distance vs time graph... a downhill slope (to the right) indicates...

• the object is speeding up.
• the object is slowing down.
• the object is moving away from the origin.
• the object is moving towards the origin.

When calculating a speed, one must know the...

• direction traveled and the time.
• distance traveled and the direction
• time and distance traveled.
• distance traveled.

To determine if an object is moving, an observer needs to use...

• a speed.
• a time.
• a velocity.
• a reference point.

The process of changing distance or position from another object

• reference point

• location

• acceleration

• motion

A vector is a quantity that has both size and 

• speed
• altitude
• acceleration
• direction

Identify the 3 things needed to determine the position of an object.

• distance, reference point, direction

• motion, reference point, direction

• direction, distance, dimension
