Velocity
The formula for finding Velocity.
What is V= d/t (distance divided by time)
The formula for finding acceleration given velocity and time.
What is a= v/t
What is the gravity constant on Earth?
What is -9.81 m/s2?
The SI unit for velocity.
What is meters per second (m/s)?
If my position is constant, my velocity is?
What is zero velocity?
If the object in the problem starts "at rest" this is the initial velocity.
What is VI= 0 m/s or V0=0 m/s
The meaning of acceleration. (Include type of quantity)
What is a vector quantity that is defined as the rate at which an object changes its velocity?
This is the difference between distance and displacement.
What is distance is a scalar quantity while displacement is a vector quantity.
This unit is used to measure acceleration.
What is m/s²?
To find instantaneous velocity, I take the what of the what graph?
What is the slope of the position versus time graph?
If the object in the problem "stops" this is the final velocity.
What is Vf=0
When acceleration is negative, but velocity is positive, what happens to the objects speed?
What is it slows down?
I'm on a hike and to begin I walk 3 miles North, then turn and walk 5 miles West. Once I make it to the summit, to return to my car, I walk 3 miles South and 5 miles East. What was my total displacement?
DAILY DOUBLE If distance is measured in millimeters and time in hours, this would be the unit for velocity.
What is millimeters per hour (mm/h)?
Two examples of projectile motion.
Answers will vary.
An airplane accelerates down a runway at 3.20 m/s(^2) for 32.8 s until it finally lifts off the ground. This is it's velocity at take-off. (Show you work).
What is 104.96 m/s?
A car starts from rest and increases its speed to 25 m/s in 5 seconds. What is the acceleration? (Show you work).
5 meters per second squared.
A car travels at a speed of 25 m/s for 20 seconds. This is how far it travels.
What is 500 m?
The difference between scalar and vector quantities.
What is scalar quantities require only magnitude while vector quantities require both magnitude and direction?
I row my boat across a 32.1 m river to the other side. The current moves my boat down the river a distance of 15.7 m. What is the magnitude of my displacement?
What is 35.73 m?
A fairground ride spins its occupants inside a large teacup. If the radius of the circular path is 10.5 m and the acceleration is 1.2g, what is the speed of the riders?
What is 11.2 m/s?
A plane is traveling at 200 m/s East. Due to turbulence, the airplane changes it speed to 150 m/s East over the course of 2 minutes. This is the plane's acceleration. (Consider East to be the positive direction)
-0.42 m/s^2
A car is driving at 30 km/h over the course of 30 minutes. This is how far it travels in m.
What is 15000 meters?
This is the conversion of 100 km/h to m/s
What is 27.78 m/s
Your friend throws a rock off of a cliff straight down with an initial speed of 10.0 m/s. Using a stopwatch, you determine it takes the rock 3.2 s to hit the ground below. How high is the cliff?
What is 82.2 m?
