Speed, velocity, distance and displacement

Question 1

What is the difference between speed and velocity?

Answer 1

• Speed is a scalar quantity: only has a magnitude
• Velocity is a vector quantity: has both a magnitude and a direction

Question 2

What is the difference between distance and displacement?

Answer 2

• Distance is a scalar quantity: only has a mangitude
• Displacement is a vector quantity: has both a magnitude and direction

Question 3

Equation of speed and velocity

Answer 3

• Speed (m/s) = distance (m) / time (s)
• Velocity (m/s) = displacement (m) / time (s)
