A straight line on a distance-time graph indicates
constant speed
.
True
What does a horizontal line on a distance-time graph indicate?
Stationary motion
What does the horizontal axis of a distance-time graph represent?
Time
What does the gradient of a distance-time graph represent?
Speed
An accelerating object on a distance-time graph is represented by a curved line that becomes
steeper
Match the type of motion with its distance-time graph shape:
Constant Speed ↔️ Straight line
Accelerating ↔️ Curved line, steeper
Stationary ↔️ Horizontal line
The vertical axis of a distance-time graph represents
distance
The speed of an object can be calculated from a distance-time graph by finding the
gradient
How can the speed of an object be calculated from a distance-time graph?
By finding the gradient
Match the motion type with its distance-time graph shape:
Stationary ↔️ Horizontal line
Decelerating ↔️ Curved line, flatter
What does the shape of a distance-time graph reveal about an object's motion?
Type of motion
What does the vertical axis of a distance-time graph represent?
Distance
How is the gradient of a distance-time graph calculated?
Change in Distance / Change in Time
A straight line on a distance-time graph indicates
constant speed
True
A
distance-time graph
shows how the
distance
travelled by an object changes over
time
A curved line flattening on a distance-time graph indicates
deceleration
.
True
A distance-time graph can be used to determine an object's speed and
acceleration
.
True
Steps to analyze a distance-time graph:
1️⃣ Identify the axes
2️⃣ Examine the shape of the graph
3️⃣ Determine the type of motion
4️⃣ Calculate the speed
The gradient of a straight line on a distance-time graph is constant, indicating
constant speed
.
True
A distance-time graph showing constant speed is represented by a
straight
What is the formula for calculating speed from a distance-time graph?
Change in Distance / Change in Time
A horizontal line on a distance-time graph indicates the object is
stationary
True
The gradient of a distance-time graph represents the
speed
A curved line that gets flatter on a distance-time graph indicates
decelerating
A car travelling at a steady 60 mph is an example of motion with a
constant
gradient.
If a distance-time graph shows a rise of 20 meters and a run of 5 seconds, what is the speed?
4 m/s
A curved line that gets steeper on a distance-time graph indicates
acceleration
True
In a distance-time graph, the horizontal axis represents
time
Match the motion type with its distance-time graph shape:
Accelerating ↔️ Curved line, steeper
Decelerating ↔️ Curved line, flatter
A flatter gradient on a distance-time graph indicates a lower
speed
True
Match the motion type with its distance-time graph shape:
Constant Speed ↔️ Straight line
Stationary ↔️ Horizontal line
Decelerating ↔️ Curved line, flatter
