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
A rock is dropped from a garage roof from rest. The roof is 6.0 m from the ground. How long does it take to hit the ground?
1.1 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
A projectile is shot upward at 189 m/s from a height of 20 m off the ground. How long will it take for the projectile to be at ground level?
38.7 seconds
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
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 stone is thrown horizontally at 8.0 m/s from a cliff 80m high. How far from the base of the cliff will the stone strike the ground?
32m
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 bald eagle in level flight at a height of 135m drops the fish it caught. If the eagle’s speed is 25.0 m/s how far from the drop point will the fish land?
132 m
