Understanding Motion: Speed, Velocity, and Acceleration

If a bus travels 40 km in 1 hour, what is its speed?

• 60 km/h

• 20 km/h

• 80 km/h

• 40 km/h

What is the primary difference between speed and velocity?

• Speed is always greater than velocity.

• Velocity includes direction, speed does not.

• Velocity is always greater than speed.

• Speed includes direction, velocity does not.

How does velocity change if a bus maintains the same speed but changes direction?

• Velocity remains the same.

• Velocity changes.

• Velocity decreases.

• Velocity increases.

What does acceleration describe in terms of motion?

• The speed of an object.

• The direction of an object.

• The rate of change of velocity.

• The distance traveled by an object.

If a bus speeds up from 40 km/h to 60 km/h in 5 seconds, what is its acceleration?

• 2 km/h per second

• 6 km/h per second

• 4 km/h per second

• 5 km/h per second
