# Vectors vs Scalars

### Physics Variables - Scalars and Vectors - Clear Lake High School - Berger

What is the definition of Acceleration? “how quickly is velocity changing” = rate of change in velocity (m/s^2)
What is the definition of Velocity? “how fast” = rate of change in position (m/s)
What is the definition of Displacement? “how far” = change in position (meters)
Distance: (identify as vector or scalar; give units) scalar - meters
Displacement: (identify as vector or scalar; give units) vector - meters
Velocity: (identify as vector or scalar; give units) vector - m/s
Speed: (identify as vector or scalar; give units) scalar - m/s
Acceleration: (identify as vector or scalar; give units) vector - m/s^2
Time: (identify as vector or scalar; give units) scalar - seconds
Mass: (identify as vector or scalar; give units) scalar - kilograms
Energy: (identify as vector or scalar; give units) scalar - joules
Power: (identify as vector or scalar; give units) scalar - watts
Temperature: (identify as vector or scalar; give units) scalar - kelvin
Area: (identify as vector or scalar; give units) scalar - m^2
Volume: (identify as vector or scalar; give units) scalar - m^3
Force: (identify as vector or scalar; give units) vector - newtons
1 centimeter = __________ meters 1 cm = .01 m and 1 m = 100 cm
1 kilogram = __________ grams 1 kg = 1000 g and 1 g = .001 kg
1 millimeter = __________ meters 1 mm = .001 m and 1 m = 1000 mm
The slope of the Position vs time graph is called the ____________ "velocity"
The slope of the Velocity vs time graph is called the ____________ "acceleration"
If acceleration is zero then the velocity is ________________. ___ then the velocity is constant.
If velocity is constant then the acceleration is ________________. ___ then the acceleration is zero.
