What is the formula for calculating speed?

• Speed = distance ÷ time

• Speed = time ÷ distance
• Speed = distance + time
• Speed = distance - time
• Speed = time × distance

How does the precision of measuring tools affect the accuracy of distance and time measurements?

• Higher precision leads to lower accuracy
• Higher precision leads to higher accuracy
• Precision has no effect on accuracy
• Higher precision affects time measurements only
• Higher precision affects distance measurements only

What are some factors to consider when choosing a mode of transportation?

• Speed, cost, and environmental impact
• Distance, cost, and availability
• Speed, distance, and personal preference
• Cost, availability, and personal preference
• Environmental impact, availability, and personal preference

Which unit is used to measure force?

• Meters per second (m/s)
• Newtons (N)
• Kilograms (kg)
• Joules (J)
• Watts (W)

What is the relationship between force and motion?

• Force changes motion

• Force decreases motion
• Force has no effect on motion
• Force changes the direction of motion
• Force changes the type of motion

How is Time calculated using distance and Speed?

• Time = distance ÷ Speed

• Time = distance + speed

• Time = distance × Speed

• Time = distance - speed

• time = speed ÷ distance

What do Newton's Laws of Motion describe?

• The behavior of objects under the influence of forces
• The relationship between distance and time
• The conversion of units in transportation
• The precision of measuring tools
• The calculation of speed using distance-time graphs

What is the unit of measurement for speed?

• Newtons (N)
• Meters per second (m/s)
• Kilograms (kg)
• Joules (J)
• Watts (W)

How can distance-time graphs be used to analyze the speed of an object?

• By calculating the slope or gradient of the line
• By measuring the area under the graph
• By determining the y-intercept of the line
• By counting the number of points on the graph
• By measuring the time interval between points on the graph

What is the impact of transportation systems on the economy, society, and environment?

• Transportation systems have a significant impact on the economy, society, and environment
• Transportation systems have no impact on the economy, society, or environment
• Transportation systems only impact the economy
• Transportation systems only impact society
• Transportation systems only impact the environment
