What is the formula for speed?
Speed = Distance / Time
s=d/t
What is the formula for velocity?
Velocity = Displacement/ Time with a direction
v = ∆x/t
What is the formula for acceleration?
Acceleration = Final Velocity - Initial Velocity / change in time
a=(vf-vi)/t
What are three ways we can tell if something is accelerating?
speeding up, slowing down, changing direction
What is km/hr2, south.. a possible unit for?
Acceleration
Distance = 20 meters Time = 4 seconds Direction = south What is the velocity of this object?
5 m/s south
What does a distance vs time graph with a straight line (linear / or \) indicate about a moving object?
It's moving at a constant speed
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
How would you describe negative acceleration? You must use the word "velocity".
decrease in velocity over time
For what formula would kilometers/hour east be a possible unit?
velocity
How would you describe the acceleration of this object? - 14 m/s squared, east
negative acceleration, decrease in 14 m/s every second, the object is slowing down
What does a negative sloped line on a distance vs time graph indicate?
The object is traveling back towards the starting point.
