Physical Quantities
What is the difference between scalar and vector quantities?
A scalar is just magnitude/quantity and vector is magnitude/quantity and direction
What is the difference between distance and displacement?
What is distance is the length of the path taken and displacement is the distance from start to finish (straight line).
Define scalar.
What is a physical quantity with only magnitude.
What is the name of this class?
Give 2 examples of vector quantities.
What is displacement, velocity, force, acceleration...
You went north 2 meters, west 2 meters, south 2 meters, and east 2 meters. What is your displacement?
0 meters.
Is speed a scalar or vector quantity? Why?
What is scalar because no direction.
Define speed.
What is the rate of change over a period of time.
Define Conceptual
Relating to or based on mental concepts.
Give 3 examples of scalar quantities.
What is speed, distance, mass, energy, temperature, length, volume...
Is displacement scalar or vector? Why?
What is vector because it has both a magnitude and direction.
What is the equation for speed and velocity?
What is speed= distance/ time // velocity= displacement/ time
Define acceleration.
Rate at which velocity changes with time, in terms of both speed and direction.
A push or a pull
What is a force?
After school Bob decided to go the bakery that was 5 km from school, he had to walk north to get there. Is this a scalar or vector quantity? Why?
What is vector, because it has direction (north) and magnitude (5km)
You went north 2 meters, west 2 meters, south 2 meters, and east 2 meters. What is your distance?
8 meters
The bird's flight took 300s, and the bird went 42 meters, find the bird's speed.
What is 0.14 m/s
Define displacement.
What is the distance in a straight line from start to finish.
What is the force equation?
F=ma
Tony ran north 3 meters and west 5 meters. His distance was 8 meters. Is this scalar or vector? Why?
What is scalar, because only magnitude.
Shauna rode a bike 10m west and then turned North and went 5m. She got turned and went 3m East, and ended going 5m south. What was her distance and displacement.
What is Distance=23m Displacement= 7m West
It took the car 40s to travel 20 meter distance and the displacement was 15 meters. What is the car's velocity?
What is 0.375 m/s
A car accelerates from 5 m/s (Vi) to a speed of 20 m/s (Vf) in 0s to 5s (tf - ti = 5s). What is the average acceleration of the car?
3 m/s2
