EOC Semester 1 Review

Velocity is

• speed and direction
• speed and time
• distance and time
• acceleration and direction

Speed is determined by which 2 factors

• distance and acceleration
• velocity and motion
• distance and time
• acceleration and distance

average speed is 

• adding up all the speeds and dividing by the total number of speeds
• adding up all the distances and dividing by velocity
• what you think you are going
• total distance divided by total time

A plane is flying 300m/s North.  This is the plane's ______

• average speed
• velocity
• constant speed
• acceleration

The distance-time graph below represents the position of an object moving in a straight line. What is the speed of the object during the time interval t = 2.0 seconds to t = 4.0 seconds?

• 10 m/s
• 0.1 m/s
• 7.5 m/s
• 5 m/s

• during time 0 to 2.0 the object had the fast speed
• during time 2.0 to 4.0 the object had the fastest speed
• during time 4.0 to 6.0 the object had the fastest speed

• The object was stopped between time 0 to 2 s
• The object was going the slowest during time 2.0 to 4.0
• the object was stopped from time 4.0 to 6.0
• The object was going a constanct speed from 4.0 to 6.0

What is the average speed of superman if he traveled 5,000 m in 10 s?

• 50,000 m/s
• 0.0002 m/s
• 500 m/s
• too fast to calculate

What is my average speed if I traveled 25 km in 10 min

• 2.5 m/s
• 2.5 km/min
• 250 m/s
• 250 km/min

A change in velocity over time is

• motion
• speed
• acceleration
• distance
