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.

Front

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

Back

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

Front

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

Back

A sloping line upwards represents positive acceleration, meaning the object is speeding up.

Front

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

Back

A sloping line downwards indicates negative acceleration, meaning the object is slowing down.

Front

What does a vertical line on a Speed-Time Graph mean?

Back

A vertical line is not possible in a Speed-Time Graph as it would imply infinite speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of speed over time.

Front

What is deceleration?

Back

Deceleration is a decrease in speed, or negative acceleration.

Front

If a car's speed increases from 20 m/s to 40 m/s in 10 seconds, what is its acceleration?

Back

Acceleration = (Final Speed - Initial Speed) / Time = (40 m/s - 20 m/s) / 10 s = 2 m/s².

Front

What does it mean if the speed is 0 m/s?

Back

A speed of 0 m/s means the object is at rest.

Front

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

Back

The area under the Speed-Time Graph represents the total distance traveled.
