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 symbol for change in distance (or displacement)
x or d
The SI unit for velocity.
What is meters per second (m/s)?
This is the first step of the scientific method
What is observe a phenomena?
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?
In this step, you make an educated guess about the outcome of your experiment based on prior knowledge.
What is forming a hypothesis?
If the object in the problem "stops" this is the final velocity.
What is Vf=0
What it means to have constant acceleration.
What is an accelerating object will change its velocity by the same amount each second?
What is the formula for finding distance if you have average velocity and time as your "knowns"?
Dx= v/t
If distance is measured in millimeters and time in hours, this would be the unit for velocity.
What is millimeters per hour (mm/h)?
This crucial step involves designing and conducting experiments to test your hypothesis.
What is experimentation?
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 speed 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?
After gathering data, you perform this step to make sense of your results and determine if they support your hypothesis.
What is analyzing data and drawing conclusions?
A car drives down a 40 km winding path that travels 30 km North over the course of 1 hour. This is the speed and velocity of the car in m/s.
What is a speed of 11.11 m/s and a velocity of 8.33 m/s North?
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
This final step involves sharing your findings with others and potentially inspiring new questions for further research.
