Understanding Speed and Distance Relationships

What is the formula to calculate speed?

• Speed = Distance × Time

• Speed = Distance ÷ Time

• Speed = Time ÷ Distance

• Speed = Distance + Time

If a car travels 150 kilometers in 3 hours, what is its average speed?

• 45 km/h

• 50 km/h

• 55 km/h

• 60 km/h

Explain how velocity differs from speed.

• Velocity includes direction, while speed does not.

• Speed includes direction, while velocity does not.

• Both speed and velocity include direction.

• Neither speed nor velocity include direction.

A cyclist accelerates from rest to a speed of 10 m/s in 5 seconds. What is the cyclist's acceleration?

• 1 m/s²

• 2 m/s²

• 3 m/s²

• 4 m/s²

Analyze the following data: A car travels 100 meters in 5 seconds, then 200 meters in 10 seconds. What pattern can you identify in the car's speed?

• The car's speed is decreasing.

• The car's speed is constant.

• The car's speed is increasing.

• The car's speed is fluctuating.

A runner's velocity changes from 5 m/s to 15 m/s in 2 seconds. Calculate the runner's acceleration.

• 3 m/s²

• 4 m/s²

• 5 m/s²

• 6 m/s²

What is the relationship between acceleration and velocity when an object is moving in a straight line?

• Acceleration is the rate of change of velocity.

• Velocity is the rate of change of acceleration.

• Acceleration and velocity are the same.

• There is no relationship between acceleration and velocity.

Interpret the following scenario: A car's velocity-time graph shows a straight line with a positive slope. What does this indicate about the car's motion?

• The car is moving at a constant speed.

• The car is accelerating.

• The car is decelerating.

• The car is stationary.
