Vectors
About the Lecture
The lecture Vectors by Jared Rovny, PhD is from the course Translational Motion.
Included Quiz Questions
Which two aspects define a vector quantity?
- Magnitude and direction
- Location and magnitude
- Location and direction
- Position and time
- Acceleration and time
What is the difference between a scalar and a vector quantity?
- A vector has magnitude and direction, while a scalar has only a magnitude.
- A vector has a specified location, while a scalar is just a number.
- A vector is a sum of at least two scalars.
- A vector only has direction, while a scalar has magnitude.
- A vector is used to represent positions, while a scalar represents magnitudes.
What is the addition of the velocity vectors v₁ = (100 km/h, 200 km/h) and v₂ = (-200 km/h, 400 km/h)?
- v₁ + v₂ = (-100 km/h, 600 km/h)
- v₁ + v₂ = (500 km/h, 0 km/h)
- v₁ + v₂ = (-100 km/h, 0 km/h)
- v₁ + v₂ = (500 km/h, 600 km/h)
- v₁ + v₂ = (300 km/h, 600 km/h)
