Exploring Distance-Time Graphs

The video tutorial introduces motion graphs, explaining how they describe the motion of objects. It covers key terms like speed, velocity, and acceleration, and demonstrates how to interpret distance-time graphs. The tutorial also discusses constant speed, acceleration, and how to solve practice problems using these graphs.

What is the main difference between speed and velocity?

• Velocity is measured in meters, speed in seconds.

• Speed includes direction, velocity does not.

• Velocity includes direction, speed does not.

• Speed is always constant, velocity changes.

In a distance-time graph, what does a horizontal line indicate?

• Constant speed

• Acceleration

• Deceleration

• No motion

What does a straight line in a distance-time graph represent?

• No motion

• Constant speed

• Acceleration

• Changing speed

How can you identify acceleration in a distance-time graph?

• By a horizontal line

• By a straight line

• By a curved line

• By a downward slope

What does a curved line in a distance-time graph indicate?

• Constant speed

• No motion

• Acceleration

• Deceleration

Which type of motion is represented by a straight line that changes slope in a distance-time graph?

• Variable speed

• Constant speed

• Acceleration

• Deceleration
