Speed
Zebras can move at a constant velocity of 16 m/s, so it'll take a zebra this long to travel a kilometer.
62.5 seconds
Earthquake? Not always! It's also the size of a vector!
Magnitude
This acceleration will nearly always pull down by 9.8 m/s^2
The Acceleration due to Gravity
The x and y directions never interact, save for this quantity.
Time
The most common one of these is supplied by gravity and measures 9.8 m/s^2
Acceleration
800 m
This is the magnitude of a bulldozer traveling at
v = (12 m / s)x + (16 m/s)y
|v| = 20 m/s
An object released from rest 20 meters from the ground takes this long to fall.
2 seconds
The x-direction of projectile motion is uniform, so there's only one equation; this equation!
x = v t
Where am I? I could tell you if I knew how far away I was from my origin, also known as this quantity.
Displacement
This type of motion is what you get whenever acceleration has left the squad.
Uniform
These are the components of a vector a = 60 at 30 degrees from the horizontal.
x: 52
y: 30
Hang-time is a useful quantity for when the total displacement in the y-direction is zero, making the final velocity equal to -1 * (initial velocity).
This is the equation for hang-time
t = (v_f - v_0) / a
A coin thrown with a horizontal velocity of 4 m/s at a height of 2 m will land this far away.
x = 2.5 m
This fast quantity can point forward, backward, up, down, or any other direction.
Velocity
This equation solves for the x-component of velocity in a projectile motion system.
v = x / t
Also a greeting given by dogs, this is how you geometrically add vectors.
Tail-to-tip
An object thrown up at 10m/s that lands going 40m/s has moved through this y-displacement.
y = 75 m.
A cannon firing at 400 m/s at 12 degrees from the horizontal will reach a maximum y-displacement of this.
y = 353m
Something moving without an acceleration is known as this. How spiffy!
This is the same time that it takes light (v = 3*10^8 m/s) to reach Mars from the Earth (x = 2.54 * 10^11 m)
846 seconds (14 minutes)
49 degrees
An object launched at 12 m/s up will take this long to hit the ground 10 meters down.
t = 3.1 s
A golfer chips a ball at 70 degrees with a speed of 12 m/s. This is the distance away from the golfer the ball will land.
x = 9.2 m
