Which of the following is a scalar quantity?

• Displacement

• Distance

• Velocity

• Acceleration

Which of the following is a vector quantity?

• Speed

• Distance

• Displacement

• Time

A car travels 300 km in 6 hours. What is its speed?

• 40 km/hr

• 50 km/hr

• 60 km/hr

• 70 km/hr

If a person walks 4 m East, 2 m South, 4 m West, and 2 m North, the total displacement is:

• 0 m

• 4 m

• 6 m

• 12 m

Distance measures the:

• Starting point only

• Shortest path between two points

• Total path traveled

• Direction of movement

If a car goes 100 km North and returns 100 km South, the total displacement is:

• 200 km

• 0 km

• 100 km

• 50 km

Speed is calculated using:

• s = d × t

• s = d / t

• s = t / d

• s = v + a
