Speed
What is the equation for speed?
s = d / t
What is the formula for distance?
What is the velocity equation?
v = d / t d= displacement
TRUE OR FALSE: If the distance increases while time stays the same, speed increases too.
TRUE
what is the acceleration formula?
a = vf - vi / t
What is the speed of a plane that travels 624 meters in 8 seconds?
S = 78 mps
100 m
What is the velocity of a car which travels 180 miles east over the course of 3 hours?
What is D on the velocity triangle?
Displacement: how far you are from where you began

Ben walks to a friend's house. He walks 750 meters North, then realized he walked too far. He turns around and walks 250 meters South. The entire walk takes him 25 seconds. What is his velocity?
V = 20 mps South
Can you accelerate if your speed is constant?
Yes
What do Vf + Vi stand for?
Vf = final velocity (ending)
Vi = initial velocity (starting)
What is speed?
Speed is how fast an object moves
A submarine travels at 25 m/s for 2 minutes. How far does it travel?
3,000 m
How far will an object travel in 5 minutes if its moving at an average velocity of 6 m/s?
D = 1800 miles
