Understanding Motion and Graphs

How can you determine the speed from a distance-time graph?

• Speed is found by averaging the distances.

• Speed is calculated by the area under the graph.

• Speed is determined by the y-intercept of the graph.

• Speed is determined by the slope of the distance-time graph.

What is uniform motion?

• Motion that varies in speed and direction.

• Uniform motion is motion at a constant speed in a straight line.

• Motion that involves acceleration and deceleration.

• Motion in a circular path at varying speeds.

If a car travels 100 meters in 5 seconds, what is its average speed?

• 15 meters per second

• 20 meters per second

• 30 meters per second

• 25 meters per second

What does a horizontal line on a speed-time graph indicate?

• Variable speed

• Increasing speed

• Constant speed

• Decreasing speed

How do you calculate distance using speed and time?

• Distance = Time ÷ Speed

• Distance = Speed × Time

• Distance = Speed - Time

• Distance = Speed + Time

What does the area under a speed-time graph represent?

• Average speed of the object.

• Acceleration of the object over time.

• Total distance traveled by an object.

• Total time taken for the journey.

If a distance-time graph is a straight line, what type of motion is occurring?

• Accelerated motion

• Variable motion

• Uniform motion

• Resting motion

What is the formula for calculating average speed?

• Average Speed = Total Time / Total Distance

• Average Speed = Total Distance / Total Time

• Average Speed = Total Distance + Total Time

• Average Speed = Distance x Time

In a distance-time graph, what does a steeper line indicate?

• A steeper line indicates a lower speed.

• A steeper line indicates no movement.

• A steeper line indicates a constant speed.

• A steeper line indicates a higher speed.

If a cyclist travels at a constant speed, how would their speed-time graph look?

• A horizontal line.

• A diagonal line increasing upwards.

• A wavy line fluctuating up and down.

• A diagonal line decreasing downwards.
