What is the formula for speed?
Speed = Distance / Time
100
What is the formula for velocity?
Velocity = Distance / Time with a direction
100
What is the formula for acceleration?
Acceleration = Final Velocity - Initial Velocity / change in time with a direction
100

A change in motion is a result of _____ forces

unbalanced forces

200
How is speed different from velocity?
velocity needs a direction
200
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
200

What are three ways we can tell if something is accelerating?

speeding up, slowing down or changing directions

200

Another term for net force is

sum of forces

300

What is the average speed of a cow that walks east 60 meters in 90 seconds? (Round to the nearest tenth)

.7 m/s

300

Distance = 20 meters Time = 4 minutes Direction = south What is the velocity of this object?

0.0833 m/s south

300
Final Velocity = 50 m/s south Initial Velocity = 60 m/s south Time to change velocity = 5 seconds What is the acceleration of this object?
-2 m/s squared, south
300

define inertia

a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

400

A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?

40 meters

400
An object travels 25 meters in 2 seconds east. What is it's velocity?
12.5 m/s east (must include direction!)
400
How would you describe negative acceleration? You must use the word "velocity".
decrease in velocity over time
400

Give two different examples of inertia (a moving and non-moving object)

answers may vary but should show that a non-moving object will stay stationary unless acted upon and a moving object will have no change in motion unless acted upon by an external force

500
What is the speed of an object moving east for 6 seconds at 105.3 m/s?
105.3 m/s
500
A pink alien moved south in it's spacecraft 2 km at a rate of 20 m/s. How much time did it take him to do this in seconds?
100s
500
How would you describe the acceleration of this object? - 14 m/s squared, east
negative acceleration, decrease in 14 m/s every second
