Speed, Time, and Distance

What does a distance-time graph represent?

• The relationship between distance traveled and time taken.

• The direction of an object's motion.

• The acceleration of an object.

• The speed of an object.

How can you interpret a distance-time graph?

• A distance-time graph shows the relationship between speed and time, and can be used to analyze the motion of an object.

• A distance-time graph shows the relationship between acceleration and time, and can be used to analyze the motion of an object.

• A distance-time graph shows the relationship between distance and time, and can be used to analyze the motion of an object.

• A distance-time graph shows the relationship between distance and speed, and can be used to analyze the motion of an object.

What does a flat horizontal line on a distance-time graph indicate?

• The object is not moving

• The object is accelerating.

• The object is changing direction.

• The object is moving at a constant speed.

What does a steep line on a distance-time graph indicate?

• Low speed or rate of change

• No movement

• Negative speed or rate of change

• High speed or rate of change

If the distance-time graph is a straight line, what can you say about the speed?

• The speed is constant. (Known as uniform motion.)

• The speed is variable.

• The speed is decreasing.

• The speed is increasing.

If the distance-time graph is a curve, what can you say about the speed?

• The object is at rest.

• The speed is not constant.

• The speed is constant.

• The speed is decreasing.

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

• speed = distance / time

• speed = time / distance

• speed = change in distance / change in time

• speed = distance + time

What is the formula to calculate speed?

• Speed = Distance x Time

• Speed = Distance - Time

• Speed = Distance / Time

• Speed = Distance + Time

If the speed is constant, what does the distance-time graph look like?

• Dotted line

• Vertical line

• Straight line

• Curved line

If the speed is changing, what does the distance-time graph look like?

• Horizontal

• Curved

• Straight

• Vertical
