Understanding Motion and Distance-Time Graphs

What is the primary difference between speed and velocity?

• Speed includes direction, while velocity does not.

• Velocity includes direction, while speed does not.

• Velocity is always greater than speed.

• Speed is measured in meters per second, while velocity is not.

In a distance-time graph, what does the gradient of the line represent?

• The time taken

• The speed of the object

• The total distance traveled

• The acceleration of the object

If a distance-time graph shows a flat line, what does this indicate about the object's motion?

• The object is moving in reverse.

• The object is stationary.

• The object is moving at a constant speed.

• The object is accelerating.

How can you tell if an object is accelerating on a distance-time graph?

• The line is straight and sloped.

• The line is flat.

• The line is curved upwards.

• The line is curved downwards.

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

• The object is moving faster.

• The object is moving slower.

• The object is stationary.

• The object is changing direction.
