Question

which quantities are scalar? (1 point)
○ speed and velocity
○ force and energy
○ time and temperature
○ distance and displacement

Explanation:

• Speed and velocity: Speed is scalar (magnitude only), velocity is vector (magnitude + direction).
• Force and energy: Force is vector (has direction), energy is scalar.
• Time and temperature: Both have only magnitude, no direction.
• Distance and displacement: Distance is scalar, displacement is vector (magnitude + direction from start to end).

Answer:

time and temperature
