Speed, velocity, distance and displacement Flashcards
1
Q
What is the difference between speed and velocity?
A
- Speed is a scalar quantity: only has a magnitude
- Velocity is a vector quantity: has both a magnitude and a direction
2
Q
What is the difference between distance and displacement?
A
- Distance is a scalar quantity: only has a mangitude
- Displacement is a vector quantity: has both a magnitude and direction
3
Q
Equation of speed and velocity
A
- Speed (m/s) = distance (m) / time (s)
- Velocity (m/s) = displacement (m) / time (s)
