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

What is acceleration toward the center of a curved or circular path?

centripetal acceleration

If an object has a velocity of 8 m/s and a momentum of 40 kg*m/s, what is the mass of the object?

m = p/v 

m = 40/8

m = 5kg

200

What is motion?

A change in position relative to a frame of reference.

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 changing direction
200

What is the speed at any single instant of time?

instantaneous speed

If a car travels 66 km in 1.5 hours, what is the speed of the car? 

S = D/T

S = 66/1.5

S = 44 km/hr

What is the average speed of a cow that walks east 60 meters in 90 seconds? (Remember, the units must be m/s or km/hr)
.7 m/s
300
Distance = 20 meters Time = 4 minutes Direction = south What is the velocity of this object?
5 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

If an object's velocity increases from 5 m/s to 15 m/s in 2 seconds, what is its acceleration?

A = (Vf - Vi) / t

A = (15 - 5) / 2

A = 5 m/s2

If a 1500 kg car has a momentum of 30,000 kg⋅m/s, what is its velocity?

P = MV

V = P / M

V = 1500 / 30,000

V = 0.05 m/s
