Speed - Time Graph

Front

What is a Speed-Time Graph?

Back

A Speed-Time Graph is a visual representation that shows how speed changes over time. The x-axis represents time, while the y-axis represents speed.

Front

What does a horizontal line on a Speed-Time Graph indicate?

Back

A horizontal line indicates that the object is traveling at a constant speed.

Front

What does a sloping line upwards on a Speed-Time Graph represent?

Back

A sloping line upwards indicates that the object is accelerating, meaning its speed is increasing over time.

Front

What does a sloping line downwards on a Speed-Time Graph indicate?

Back

A sloping line downwards indicates that the object is decelerating, meaning its speed is decreasing over time.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed. It can be positive (speeding up) or negative (slowing down).

Front

What is deceleration?

Back

Deceleration is a type of acceleration that occurs when an object slows down.

Front

If a car's speed changes from 0 m/s to 20 m/s in 4 seconds, what is its acceleration?

Back

Acceleration = (Final Speed - Initial Speed) / Time = (20 m/s - 0 m/s) / 4 s = 5 m/s².

Front

What does it mean if a Speed-Time Graph shows a steep slope?

Back

A steep slope indicates a high rate of acceleration or deceleration.

Front

What does it mean if a Speed-Time Graph shows a flat line at 0 m/s?

Back

A flat line at 0 m/s indicates that the object is at rest.

Front

How can you determine the total distance traveled from a Speed-Time Graph?

Back

The total distance traveled can be found by calculating the area under the graph.
