Force and Motion 2 (Speed/Distance/Time)

Front

What is the definition of speed in the context of motion?

Back

Speed is the distance traveled per unit of time, typically expressed in miles per hour (mph) or kilometers per hour (km/h).

Front

How do you calculate time when given distance and speed?

Back

Time can be calculated using the formula: Time = Distance ÷ Speed.

Front

What is the relationship between speed, distance, and time?

Back

The relationship is defined by the formula: Speed = Distance ÷ Time.

Front

If a car travels 100 miles at a speed of 50 miles per hour, how long does the trip take?

Back

The trip takes 2 hours (Time = Distance ÷ Speed = 100 miles ÷ 50 mph).

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken for the trip.

Front

How can a graph represent the motion of an object?

Back

A graph can show the relationship between distance and time, indicating how speed changes over time.

Front

What does a steeper slope on a distance-time graph indicate?

Back

A steeper slope indicates a higher speed of the object.

Front

If a student walks to school at a speed of 3 km/h for 20 minutes, how far do they walk?

Back

They walk 1 km (Distance = Speed × Time = 3 km/h × (20/60) hours).

Front

How do you convert minutes into hours for calculations involving speed?

Back

To convert minutes into hours, divide the number of minutes by 60.

Front

What is the formula to find distance when speed and time are known?

Back

Distance = Speed × Time.
