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
